What does PokerSnowie stand for?

Depending on the context, PokerSnowie may either stand for the AI (the "brain") or the actual software tool that is powered by the brain.

PokerSnowie is the name behind the concept of increasing game proficiency, overall gaming ecosystem health and entertainment value using mathematical modelling and artificial intelligence (neural networks) to develop the strongest, most balanced and ultimately un-exploitable gameplay possible. We want to give everyone the chance to improve their game in an effective yet responsible way for the overall good of the gaming community.

We've already put our ambition into practice in the form of BackgammonSnowie, which showed fantastic results and a lot of support from novice and professional Backgammon players alike.

With poker increasing in popularity, in addition to the fact that it's a similarly skill-based game with some elements of luck, it was the next logical step in our progression, and resulted in PokerSnowie.

PokerSnowie is a very strong No Limit Hold'em poker player. Its knowledge is based on artificial intelligence neural networks and mathematical models, and its experience is the result of trillions of hands of gameplay against itself over the course of a decade.

PokerSnowie has no expert knowledge built in and its goal is to develop a perfectly balanced and un-exploitable strategy, making it the perfect partner to help you develop a long term winning strategy.

 
What is PokerSnowie?

PokerSnowie is a very strong No Limit Hold'em poker player. Its knowledge is based on artificial intelligence neural networks and mathematical models, and its experience is the result of trillions of hands of gameplay against itself over the course of a decade.

PokerSnowie has no expert knowledge built in and its goal is to develop a perfectly balanced and un-exploitable strategy, making it the perfect partner to help you develop a long term winning strategy.

 
But isn't the human element responsible for world-class playing ability?

There are occasions where using detailed knowledge of your opponents can pay off in the short term. For example, it's easy to beat a 'Rock, Paper, Scissors' player if he always picks scissors. However, taking this approach also leaves you vulnerable to being exploited yourself by opponents who know what you're doing. Play perfect strategy and even if your opponents know, they still have no counter-strategy against you and you're guaranteed to be a winning player in the long run.

 
How is PokerSnowie different to statistical tools or peer-based training/coaching programs?

Statistical tools such as HUDs (or heads-up displays) only provide figures on gameplay in order to expose and exploit weakness, and they do not take actual game strategy into account, making them unreliable for developing a long term winning strategy and improving your own game.

Peer-based training/coaching programs are based on the opinions and approaches used by highly rated players, but they also inherently contain a lot of subjectivity, which can result in adopting habits that may be detrimental to the development of your game. The problem with subjective advice is that it may not work for everyone and it opens up the possibility of being exploited yourself simply by taking this approach.

PokerSnowie is focussed on giving anyone the chance to learn a balanced gameplay that cannot be exploited. The overall aim of PokerSnowie is to provide you with the best possible way of improving your game proficiency, rather than looking for weak points in the gameplay of others.

PokerSnowie's products enable you to analyse every aspect of your game, pin-point specific errors, provide you with valuable advice on more efficient alternatives, rate your play in terms of numerous variables such as equity, error rate, balance rate and more, and also give you the perfect environment in which to put it all into practice: by playing against PokerSnowie itself!

There are simply no other tools or training/coaching options out there that give you so many real, practical, measurable – and proven! - ways to improve your game.

 
What products are powered by PokerSnowie?

PokerSnowie currently powers 2 products: the PokerSnowie software and the PreflopAdvisor, the last of which is available for free and is a great way to experience PokerSnowie's optimal gameplay capabilities.

 
Who are PokerSnowie's products for?

In a word? Anyone! The beauty of PokerSnowie's products is they're designed to improve the poker proficiency of NL Hold'em players of any level by pin-pointing specific elements of your game that could be improved AND giving you the best possible practical advice on how to do so.

 
I have a website and I would like to sell PokerSnowie, do you have an affiliates program?

Simply join as an affiliate partner, direct traffic to PokerSnowie and we will handle everything else. You can sign up here http://www.idevaffiliate.com/32296/signup.php.

 
My PokerSnowie subscription expired, can I still use PokerSnowie?

What type of hands can I analyse with PokerSnowie?

PokerSnowie only supports regular hands from NL Hold'em real money cash games (no antes, no straddles). Furthermore, the hand histories have to be written in English. Play money, tournament or SNG hands are not supported.

Furthermore, we currently fully support the following sites or networks:

  • 888
  • Boss Media (Espacejeux and others)
  • Bovada/Bodog
  • BWIN/Party
  • Chico Poker Network (as seen from Betonline)
  • Equity Poker Network (as see from FullFlush Poker)
  • Fulltilt
  • Hive Network
  • iPoker
  • Merge
  • Microgaming (MPN)
  • Ongame
  • PeopleNetwork.it
  • PKR
  • PokerStars
  • Revolution
  • Svenska Spel
  • Winamax
  • Winning Poker Network (WPN)

For best results, hands should be imported directly from the Hand history folder generated by the site/network you play on. However, if the files have been moved, yet remain unchanged by third party software, you should not experience any difficulties.

 
Which Microgaming (MPN) hand history format is supported?

Click here to download those instructions as a PDF file.

Microgaming (MPN) Poker Network
MPN saves the hand history in a file named "GameHistory.dat" which cannot be read by PokerSnowie. The workaround is to follow the these steps:
  • Go to Preferences - Hand History (other MPN skins may have a different menu).
  • Select the required hands (NL Holdem cashgame only!) according to the available options.
  • Highlight the required hands.
  • Click on the "Export and History" button.
  • Assign a file name and then save that file in .txt format which is then readable by PokerSnowie.
Summary: "Preferences" – "Hand History" - Select and mark hands - export them to a text file.
 
Can I test PokerSnowie if I don't have supported hands?

Yes, now you can. We've made available a number of sample hands which you can import into PokerSnowie to test the product. Click here to download those sample hands. Once downloaded unzip the file and it is now ready to be imported into PokerSnowie.

 
I cannot launch PokerSnowie while running PokerStars or Full Tilt

PokerSnowie is strictly a post hand analysis tool and we encourage users not to use it whilst playing online at any site.

As a matter of fact we have designed our product to automatically close or not even start when it detects a running instance of the PokerStars or Full Tilt software. In order to run PokerSnowie, any instance of Pokerstars or Full Tilt must be closed.

 
Is PokerSnowie's style maximum EV at all different stakes?

No, it is not. Especially if you play at the lower levels you could win additionally by exploiting specific weaknesses of your opponents.

However, if you execute the PokerSnowie strategy perfectly you would still win because the opponents make a lot of errors, from which you would collect EV.

 
What does EV stand for?

EV stands for "Expected Value". When browsing through your hands you will notice that PokerSnowie rates your play based on the EV. In most situations, a particular play exists that has the highest EV. There are also situations where different plays, for example a raise and a call, have the same positive EV. Or there are situations where both a fold and a bluff-raise have the same neutral EV. The EV is measured in big blinds.

 
I think PokerSnowie plays way too tight preflop. Why is that?

Regarding the ranges preflop: It is clear that against weak human opposition the opening ranges can be much wider. On the other hand, against very strong opponents the ranges of PokerSnowie are optimal.

It's also important to note that rake is incorporated in the model. Therefore, at lower stakes (where the rake is proportionally bigger) PokerSnowie plays tighter than at higher stakes.

 
Does PokerSnowie adapt to players' tendencies?

No, it does not. PokerSnowie plays independently of the characteristics of a specific opponent. So it does not take into account HUD stats or the skill level of opponents. Instead, it basically plays a game of super high stakes, where it considers that the opponents are all very strong, too.

 
What is the error rate?

The error rate gives a score for how well the session was played. It is independent of the actual outcome and only based on the skill of the player. For every betting round, the error rate sums up the EV cost of all errors, divided by the number of moves played. So the smaller the error rate the better.

Please note that the sample size needs to be big enough to get a significant error rate. Usually 5K to 10K of imported hands is enough to get a stable error rate.

Very strong high stakes players have an error rate of around 7 in ring games and 5 in heads-up games. Less experienced players and beginners often have an error rate of over 20.

 
What are Blunders?

A blunder is a costly error. The threshold for when an error is considered to be a blunder can be set within the options menu. By default the threshold is set to an EV loss of 2.0 big blinds.

The link 'Browse your blunders' lets you conveniently browse through all big errors, so that you can efficiently learn to avoid your biggest errors.

 
What does the profit and loss page indicate?

This page gives you an overview about the outcome of the session. The profit is calculated disregarding rake, with rake then deducted from that number.

The total profit is split into showdown and non-showdown hands.

 
What are Error details?

Here the error rate is broken down into the four betting rounds. You can quickly see in which round you gave up most EV.

Note that you can click on the number of blunders and errors for each round. This automatically sets the filter so that you can browse through this error type.

 
What does the balance page indicate?

The error rate measures the EV given up. You may, however, have a good error rate and a poor balance as a result of the weak/medium/strong ratio. The balance page shows you how balanced your play has been.

The 'Call' block compares your number of calls with the number of calls PokerSnowie would have played, split by each betting round. 100% is the perfect value, a number higher than 100% means that you called too often and a number lower than 100% means you didn't call enough.

The 'Bet' block does the same thing for all your bets, but split by bets with weak (as a bluff), medium and strong (for value) hands. Again 100% is best, but additionally it is important to have as similar a score as possible for each weak / medium / strong bracket. 100% weak, 100% medium and 100% strong is best, but for example 150% weak and 150% strong is a lot better than 150% weak and 50% strong. 150%/150% indicates a too high frequency of betting, but at least the ratio between weak and strong hands is right. 150%/50% is very bad, the balance is quite wrong and the opponent could easily exploit this.

The 'Raise' block has the same structure as the 'Bet' block.

Note that you can click on the numbers below the percentages, which is the number of times the player actually played that type of move. This automatically sets the filter so that you can browse through these specific actions.

 
What are playing stats?

Several statistics are shown. When possible, the stats of the player are compared with the stats PokerSnowie would have produced given the same situations. That way, it is easy to see how the player should adjust.

VPIP: Voluntarily put money in pot
Number of times the player voluntarily put money in the pot, divided by the total number of hands.

PFR: Preflop raise
Number of times the player raised at least once during preflop, divided by the total number of hands.

Aggression factor
Number of times the player made a bet or raise, divided by the total number of calls.

Fold facing bet
Number of times a player folded to a bet or a raise, divided by the total number of situations where the player was facing a bet.

SFSB: Saw flop from small blind
Number of times the player was in small blind position and was still in the hand on the flop, divided by the total number of hands sitting in small blind position.

WMSF: Won money when seeing the flop
Number of times the player won money when seeing the flop, divided by the total number of times the player saw the flop.

WTSD: Went to showdown
Number of times the player went to the showdown, divided by the total number of hands.

WMSD: Won money at showdown
Number of times the player won money at the showdown, divided by the total number of player hands at showdown.

ATSB: Attempt to steal blinds
Number of times the player opened the pot with a raise, sitting in steal position (cut-off or button).

FSBS: Folded small blind to steal
Number of times the player folded the small blind to a raise in steal position (cut-off or button), divided by the total number of steal attempts sitting in small blind position.

FBBS: Folded big blind to steal
Number of times the player folded the big blind to a raise in steal position (cut-off or button), divided by the total number of steal attempts sitting in big blind position.

 
What does the opponents’ page indicate?

The same statistics are combined for all opponents on the 'Playing stats' page. For the meaning and the definition of the stats, have a look at the playing stats.

 
What is the preflop advice table?

The preflop advice table is a great tool to visualize PokerSnowie's preflop strategy in one glance.

The table displays one field for each of the 169 different hole card combinations: the diagonal covers the pocket pairs, the upper right triangle the suited cards and the lower left triangle the off-suited cards.

The colour code indicates the advised action, green for raise, yellow for call and white for fold. If a number is displayed in the field, this is the percentage of times this hand should be raised.

It is possible that some hole cards combinations are not in the preflop range anymore. If you have previously raised and it is your turn again, you would not be holding 72o, for example, because you would have folded it already. Those fields are greyed out. However, it is still possible to see how PokerSnowie would continue with these hands, by activating the option 'show full table'.

The default table is the one for the proposed bet size, the bet sizes PokerSnowie considers as best. You can click on the buttons '1/2 POT', 'POT' and '2 POT' to switch between the bet sizes and see the alternative tables.

 
How does the hand range functionality work?

The hand range feature calculates a list of all hands that PokerSnowie would hold, given the circumstances of the game. At the top of the window the hand range is split by hand type. Clicking on the '+' sign opens the branch of the corresponding hand type and splits it further.

At the bottom all individual hands are displayed. They are grouped by hole cards that are considered the same. For example, on preflop all 12 combinations of JTo are grouped together and all 4 combinations of JTs.

The 'Combinations' column tells you the number of combinations remaining from that group. The combinations value may be further decreased by a certain percentage if PokerSnowie would have made the move the player made. If, for example, the player raised and PokerSnowie's advice is to raise 20% of the time, the combinations are multiplied by 0.2.

The 'Probability' column assigns a probability for each hand normalized over the whole hand range, so the sum of that column adds up to 100%.

The next column specifies the hand type, and the last column the draw type (if the situation is not on the river), for each hand. 'Straight (1)' is a gut shot straight draw and 'Straight (2)' an open-ended straight draw.

You can sort each column by clicking on the column name.

Please note that it can happen that no hands are found. That means that PokerSnowie would not have played the same way as the player did with any hand.

Please also have a look at possible problems with the hand range.

 
How does the range advice functionality work?

This feature is only available for the player to act. It works very similarly to the hand range feature but also constructs folding, checking/calling and betting/raising ranges.

Selecting one of those ranges provides distribution information about the hand type and details for all hands that comprise the corresponding range.

PokerSnowie has 3 different ranges for the bet sizes: 1/2 pot, pot and 2 pot. By default PokerSnowie selects the bet size it considers best, but it can be switched manually to see ranges for alternative bet sizes.

It is also possible to see how PokerSnowie would play hands that are not in its hand range anymore. Clicking 'show all hole cards' provides the evaluations for all hole cards, independent on the hand range.

 
PokerSnowie seems to show inconsistent hand ranges – why is that?

In some situations there may be an inconsistency between PokerSnowie's advice and the opponent's hand range. For example, PokerSnowie advises to call a bet on the river, while the opponent's hand range doesn't offer the right odds to call. How can there be such an inconsistency?

First of all it has to be noted, that the evaluation (the move advice) is NOT based on the hand range of the opponent. The evaluation is the output of a neural network and has evolved during training. The neural network has been trained over trillions of hands, against various counter-strategies. Therefore these evaluations are very robust and can be trusted most.

The hand range, however, is a calculation based on the evaluations of the same neural network. All legal hole cards are considered and the evaluations are used to decide which hole cards PokerSnowie would possibly hold in a certain situation.

As a consequence, the evaluation may be different than a conclusion based on the hand range of the opponent.

This, unfortunately, cannot be avoided; the problem would only vanish if the neural net was a perfect calculation of the game (and not an estimation based on pattern recognition).

The hand range can be very sensitive to small changes in a previous round. Two very similar situations on the flop may lead to quite different hand ranges on the river, if a group of hands falls out of the range due to a small EV difference on the flop. Similarly, two slightly different neural nets that play almost identically may have significantly different hand ranges.

Therefore:

  1. the right action cannot be concluded from the opponent's hand range
  2. the evaluations are robust whereas the hand range is sensitive
  3. the hand range should only be used as an indication of which hands are possible holdings
 
What does the hand evaluation panel indicate?

The evaluation panel displays PokerSnowie's advice on the current situation. On the left hand side, the player's move is described and classed as 'correct' or 'wrong'. The 'error' is simply the EV difference (in big blinds) between the best move and the played move. A mouse-over hint transforms the EV difference into the money amount given up.

On the right hand side, you can select the bet size. By default, PokerSnowie's proposed bet size, displayed in green, is already activated. For every bet size there are three possible actions: fold, check/call, bet/raise. Every action is assigned a percentage value, which is the percentage of the time the corresponding action should be played.

In most cases one move should be played 100% of the time. Sometimes, however, a mixed action is proposed. For example, 90% 0% 10% means that the hand should be folded 90% of the time, never called and 10% bluff-raised.

Next to the percentages the EV (expected value) is displayed in big blinds. Again, a mouse-over hint shows the money amounts.

Please read more how bet sizing works for PokerSnowie.

 
What does the hand strength panel indicate?

In the hand strength panel, the hand of the player is compared to the ranges of the opponents.

The scale of 'showdown strength' and 'betting strength' goes from 0.0 to 2.0, independently of the number of players still in the pot. This normalization has been done for easy comparison of the numbers and for clear classification of bets or raises with WEAK hands (as a bluff), STRONG hands (for value) and MEDIUM strength hands.

The 'showdown strength' provides an estimation of how well the specific hand would perform against the ranges of all opponents still in the pot, with no more betting allowed (as if everybody was all-in).

In the specific case of only one opponent, dividing the showdown strength by 2 gives you the player's 'equity vs. range'. For example, a value of 1.20 corresponds to 60% 'equity'; 60% chance of winning a showdown against the opponent's range.

The 'betting strength' is very similar to 'showdown strength', but it considers only the non-folding ranges of the opponents. We have defined 3 brackets. A low value classifies the hand as WEAK (0 - 0.6 on the scale), a high number would be considered as a STRONG hand (> 1 on the scale). A value between 0.6 and 1 would indicate a hand of MEDIUM strength.

Again, in the case of having only one opponent, a value of 1.20 corresponds to a 60% chance of winning against the opponent's non-folding range.

The 'betting strength' is different for each bet size. In general, the higher the bet size, the lower the betting strength.

 
What does the Analysis tools panel indicate?

This panel gives you access to some advanced features.

The 'hand range' displays a table with all hole card combinations that PokerSnowie thinks the player can still hold at this time. Learn more about the hand range.

The 'preflop advice' is only active on preflop. It displays a hole cards table with complete preflop advice for the specific situation. More details about the preflop advice table.

The 'range advice' also displays the hand range, but broken down into separate action ranges. It includes the advice on how to play each individual hand in that situation. Therefore this feature is only available for the player to act. More details about the range advice.

How does the filter manager work?

All imported hands are stored in a local database. In the filter manager, a subset of all hands can be selected. All statistics and analysis will be based on this subset.

The date range, poker rooms and stakes can all be filtered. Under 'My aliases' you should find your screen names. If this is not the case, you can select it manually from the list of screen names below.

The button 'Apply filters' activates the new filter settings and returns to the Statistics / Overview page.

The Filter Manager is divided into 3 parts (Basic, Advanced, Hole Cards):

Basic:

Date (all dates, today, yesterday, this month, this year, between dates)
Poker rooms
Stakes (includes all stakes found in the hand history files)
Screennames (if the requested screen name is not listed, clicking on the EDIT link opens another window that allows picking more screen names )
Dealt in players (2-10)

Advanced:

Positions (All positions, Dealer, Cut off, Small blind, Big blind, Other)
Selecting wins or losses, thresholds can be set (between, equal to, greater than, lower than)
The selected screen names were raised on either the flop, turn, river or on any street
The selected screen names were facing a 3 bet preflop that made them fold, call or raise (4 bet), or any of the aforementioned
The selected screen names were facing a 4 bet preflop that made them fold, call or raise (5 bet), or any of the aforementioned

Examples for all filters:

WAS RAISED: Hero was in the blinds or limped, followed by someone’s raise
FACING 3 BET PF: Hero open-raises, then someone re-raises ( 3 bets) hero
FACING 4 BET PF: Someone open-raises, hero re-raises (3 bets), action goes back to the open-raiser who then re-raises (4 bets) hero

Hole cards:

By default, all hole cards are selected. Any card in green is selected, whilst grey colour means it is not selected

Specific hole cards can be selected by clicking on the relevant squares in the matrix
These buttons allow a quicker selection of certain hand groups. To use the "suited", "off suit" or "Pairs" selection buttons, make sure you first click on "none" to deselect all cards.

Notice that all filter selections can be applied to either specifically selected sessions or to all hands in the database.

All filters can be combined with each other. The filters that are currently selected are listed in the left hand column.

All filters can be reset to default by clicking on "clear all filters".

 
How does the import manager work?

PokerSnowie analyses the hands that you played in the online Poker rooms. The import manager lets you choose hands to import and manage the imported sessions.

To start, click on 'Import files'. You will then be asked to choose one or several hand history files for importing. Alternatively, you can use 'Import folder' to import all hand histories located in that folder.

Please note that only original hand histories are supported. See a list of supported Poker rooms. Exported hand histories from third party tools are not supported.

After some time, when the analysis process is completed, you can select all or some files and view the analysis by clicking on 'View analysis'.

To manage the imported sessions, mark the desired hand histories and then either right-click on the list or use the buttons next to 'View analysis'. You can remove or rename imports and group or ungroup them.

A copy of your uploaded files is saved locally under:

C:\Users\<UserName>\My Documents\PokerSnowie\imported\ (Windows 7/8) or
C:\Documents and Settings\<UserName>\MyDocuments\PokerSnowie\imported
(Windows XP).

Please note that your previous imports that were done before the name change from "PokerCoach" to "PokerSnowie" are still located under:

C:\Users\<UserName>\My Documents\PokerCoach\imported\ (Windows 7/8) or
C:\Documents and Settings\<UserName>\MyDocuments\PokerCoach\imported
(Windows XP).

 
What options can I configure in PokerSnowie?

In the options window several options can be set.

Show hand type
If enabled, the current hand type of the player to act is displayed on the Poker table.

Move processed hands
If this box is checked, the files that you selected for imports will be moved to C:\Users\<UserName>\My Documents\PokerSnowie\imported. This avoids importing the same hands multiple times.

Blunder threshold
This option defines the EV threshold when an error is considered a blunder (big error). The default value is 2.0 big blinds.

Balance threshold
When the balance of any category in the Statistics / Balance page deviates significantly from 100%, the corresponding number is red, to draw attention to that leak. Here that threshold can be set. By default, the value is 20%.

Remove sample hands
PokerSnowie comes with some sample hands, for users that don't have their own hand histories available. Clicking on the 'Remove' button deletes these sample hands from the database. It is advisable to do so when you upload your own hand histories for the first time in order to avoid getting mixed stats with your own hands.

Avatar
You can choose an avatar to be displayed for your screen name.

Main currency
When you import hands that were all played in the same currency, that currency will be used for all profit and loss details. However, if you imported hands with mixed currencies, you can select your main currency here. All money amounts will be transformed into the main currency, using the given exchange rates (which you can edit as well).

 
How does "Challenge PokerSnowie" work?

Challenge PokerSnowie is a training feature which lets you play directly against the Artificial Intelligence engine.

Challenge PokerSnowie game configurator:

Clicking on "Challenges" in the main menu opens The challenge PokerSnowie window, which will allow you to specify some parameters for playing against PokerSnowie.

The Snowie opponents menu lets you choose how many opponents you wish to play against. The default is 1 opponent for Head's Up and you can choose up to 9 opponents for a full ring game.

The game type lets you choose between a freezeout mode or standard cash game mode. In Freezeout mode, the game ends as soon as you or all PokerSnowie opponents are eliminated.

The cash game option lets you sit down and reload your bankroll for as long as you wish. The session ends when you decide to end it.

In cash game mode, you can choose to rebuy automatically with the Auto rebuy to max threshold. By default it is set at 70% of your starting stack, but you can modify this with the selector to go down to 50% or up to 100% of your stack. Note that the PokerSnowie players reload following the same logic.

After selecting "Cash game", if you choose a buy-in equal to or lower than 50BB, you have the option to play at a CAP table by checking the box underneath the buy-in. The buy-in value will be used as the CAP value; the auto rebuy threshold will work as usual. Please note that if at the beginning of a hand, the amount of money you have at the table is greater than the CAP value, it will be reset to the CAP.

The stake level option lets you decide your stake level, from 0.5/1 to 100/200. Furthermore, there is no rake incorporated in the game.

You can choose between various starting stacks from as low as 15 BB up to 200 BB.

Right at the bottom of the Challenge PokerSnowie configurator, you can choose to remove the default "fast fold option". Fast fold means that once you fold,  a new hand is dealt right away. Otherwise a new hand would only start after the conclusion of the folded hand. Removing this option allows you to let all hands play out till the end.


Table Features:

You can open a maximum of 2 tables at the same time.

On the cash game tables, you will see your current win/loss status as well as the number of hands played at this table.

By default, new hands start automatically. You have an option to change this and pause the game with the "auto start next hand" tick box.

If you have removed the fast fold option, then you will be presented with the option to "make Snowie hole cards visible". This means all the PokerSnowie players will turn their cards at the end of each hand.


Real time evaluation:

By marking the "Real time evaluation" checkbox, players are offered an "Evaluation" button at the challenge tables. By clicking on this button a freely movable window opens and shows Snowie's recommendation for the player's hand in real time.


Post game analysis:

Once you have finished your play session, all your hands are automatically imported in PokerSnowie, where they are available for full analysis. The import process can take a couple of minutes after the end of the session. To analyse your Challenge PokerSnowie session, go to the import manager. The files from your game are called either cash_xxxxxxx or freezeout_xxxxx. Select the file you wish to analyse and click on the view analysis button to go through your play.

A copy of your uploaded files is saved locally under:

C:\Users\<UserName>\My Documents\PokerSnowie\imported\ (Windows 7/8) or
C:\Documents and Settings\<UserName>\MyDocuments\PokerSnowie\imported

Please note that your previous challenge sessions that were played before the name change from "PokerCoach" to "PokerSnowie" are still located under:

C:\Users\<UserName>\My Documents\PokerCoach\imported\ (Windows 7/8) or
C:\Documents and Settings\<UserName>\MyDocuments\PokerCoach\imported
(Windows XP).

How does bet sizing work for PokerSnowie?

In any situation, PokerSnowie has three discrete options for choosing its bet size: 0.5 pot, 1.0 pot and 2.0 pot.

This bet size depends on the specific game actions, the amounts of chips at the table, the community cards, etc. It does NOT depend, however, on the given hole cards. That means PokerSnowie chooses the bet size for its whole range of hands that it can hold at this time.

Why does the bet size not depend on the hole cards?

Imagine the following example: in a certain preflop situation you raise with AA and KK 0.5 pot (to not scare away your opponents), with your medium hands 1.0 pot (to extract good value) and with your weak hands 2.0 pot (to make the opponents fold most of the time). This strategy may work for a few hands, but once your opponents become aware of what you are doing, it is very easy for them to exploit you.

A more efficient strategy is to use just one bet size for all hands and not give away any hints about your hand strength.

Even though theoretically it can be occasionally correct to have multiple bet sizes in one situation (with different, separately balanced ranges), in practice this would be very hard to implement.

Does the bet size change the raising range?

Absolutely! PokerSnowie has different hand ranges for each bet size. PokerSnowie has learned in the following way:

  1. if my bet size is 0.5 pot, what is then my raising range?
  2. if my bet size is 1.0 pot, what is then my raising range?
  3. if my bet size is 2.0 pot, what is then my raising range?

Only after defining those 3 ranges can the next question be asked:

  1. Which bet size gives me the best EV over my whole range of hands?
What is the main difference between the raising ranges?

In general, the higher the bet size, the fewer the hands that can be used to value-raise.

A hand that is a marginal value raise with the bet size of 0.5 pot, will be called only by better hands if it is raised with a bet size of 2.0 pot, and effectively becomes a bluff at a high bet size.

The higher the bet size, the more bluff hands can be added to each value hand, because the pot odds for the opponents become less attractive with higher bet sizes.

If your bet size is 0.5 pot in the BB on preflop, for example, you should choose hands for bluffing that have enough potential when you get called. The probability of getting called is quite high, so the potential of your hand is really important.

If your bet size is higher, the priorities shift a little. If your bet size is 2.0 pot, most of the times the pot ends after your raise and the potential of the bluff hands is less important. Instead, the hands with good potential can be used for calling.

Overall, the raising ranges are constructed very differently, depending on the bet size. In general, the 2.0 pot range is much more polarized than the lower bet sizes.

Does the bet size depend on the stake level?

Yes! Whether you play $0.10/$0.20 or $10/$20 makes a huge difference with regards to the rake. The lower stakes you play, the more severe the impact of the rake. Obviously, the higher the rake impact, the more you want to end the game already on preflop (no flop no drop), so in general PokerSnowie's proposed bet sizes are higher for low stakes.

It is unusual (as of today) that players use 2.0 pot as their bet size. Why would that high bet size be correct?

PokerSnowie uses the 2.0 pot bet sizes mostly in the following situations:

  • When 2.0 pot is all-in and 1.0 pot is not all-in, there is a clear advantage for 2.0 pot: it kills the options of the opponent, he cannot re-raise anymore and is limited to fold or call.
  • When 2.0 pot is almost all-in, then the case is similar to the one above. While not killing the re-raise option completely, this bet size at least cripples the power of a re-raise.
Why is there no bet size 0.75 pot?

The available bet sizes is a design issue. In retrospective it would have been good to have also a 0.75 pot bet size, as it is a common bet size among players. On the other hand, all our simulations and calculations show that this addition would not have a significant impact on the overall performance of PokerSnowie.

However, it is planned in the future to add this bet size anyway. Unfortunately this involves quite a long training process, as not only do we need to train the bet sizes again, we also need to train the correct ranges for a 0.75pot

Does PokerSnowie play well against unusual strategies?

The training algorithm is designed in such a way that the resulting strategy is extremely well balanced and largely un-exploitable. That means that it performs well against all kinds of counter strategies. That also includes counter strategies which use overbets, mini-bets and bet sizes between the ones that PokerSnowie proposes.

I see "Suggested bet size 1 pot" while at the same time the suggested action is a fold or a call. What does that mean?

As explained above, the bet size is chosen for the whole range of hands. This bet size is displayed for information only, even when the right action with a specific hand is not a raise.
