I get this error sometimes wich I don't understand

There should be a functionality to run tournaments where you can set the payouts and rather than simulating a number of hands, simulating a tournament (until one player is left).

There is an issue that if two Players have the same 5 best cards but one of them has a higher handcard he win. But thats not right cause just the highest 5 cards are important for winning so it should be split between that. Saw it on a straight in middle cards, so all had the same straight but the bot with the highest cards won.

When the players remaining stack is too low for the minimal raise (defined by the call amount + the last raise performed on the street), -1 is given by valid_actions, though if the player has more than the call amount, he should be able to raise to that value (to go all-in)
To fix this, I changed the function legal_actions in engine/action_checker.py to:

def legal_actions(self, players, player_pos, sb_amount):
    min_raise = self.__min_raise_amount(players, sb_amount)
    max_raise = players[player_pos].stack + players[player_pos].paid_sum()
    if max_raise < min_raise:
      min_raise = max_raise = -1
        if self.agree_amount(players)>=max_raise:
            min_raise = max_raise = -1
        else:
            min_raise = max_raise = players[player_pos].stack + players[player_pos].paid_sum()
    return [
        { "action" : "fold" , "amount" : 0 },
        { "action" : "call" , "amount" : self.agree_amount(players) },
        { "action" : "raise", "amount" : { "min": min_raise, "max": max_raise } }
]

Now if the player has a stack smaller than the call amount, -1 is still returned and the player can just call, but when the player's stack is larger than the call amount, his all-in amount is returned.

PyPokerEngine is a very good framwork for poker AI development.but it is too slow!

I test it use the FishPlayer, and run 10 rounds,it take 10s on my computer.
I test another repo, https://github.com/chasembowers/poker-learn ,it can run 10000 rounds in 1 minute on my computer.

So, I use PyCharm Profile to check it.
the function _calc_hand_info_flg take more than 70% time.

Finally,I recommend use https://github.com/worldveil/deuces to speed up.
a lot of repo on github are using deuces
it's on py2, maybe you can use the fork version https://github.com/ihendley/treys

If I set blind_structure like below

emulator.set_blind_structure(11: { "ante":0, "small_blind":50 })

then small blind of round 11 becomes 50 but that of round 12 is back to initial blind amount.

The cause of source
The code update blind amount only when current round exactly matches to update timing.

Refactor code without api change

With five players and a long run, with max_round = 10000
The winner doesn't have always the total amount and I thing it's due to sides pot wrong distributed.

Are you plan to implement another games, like SNG, MTT tournaments and so on?
In cash game I expect that lost players will rebuy and continue play on the table. Because, what if I need to test 1kk rounds for 9 players?

When using the emulator code given in the Readme and error is thrown in the hand_evaluator.py file being:

IndexError: list index out of range

with

hole_flg = ranks[1] << 4 | ranks[0]

It seems this is happening at the end of the emulator's job and the ranks list is empty. It is happening in both python 3.5 and python 2.7. Is the code given in the readme perhaps a little off and is using the emulator incorrectly or is the emulator not properly functioning?

Thanks!

I have a Problem where impossible hands emerges. Example:
'TD', 'TH', '7D', 'TS', 'TD', 'TH'
You can see that 'TH' and 'TD' are double and this should be impossible.
Is there a setting to prevent this?

Write GUI support (PyPokerGUI) on README and doc cite

The constant stream of prints when running the poker game makes it very hard to track my own prints. A flag for the "setup_config" function would be nice, like
config = setup_config(max_round=10, initial_stack=100, small_blind_amount=5, show_game_messages=False)

I know this repo is not maintained, I still post this issue here in case anyone being confused about its behavior.

Issue

Here's what I encountered:

player [SixPlayer] gets hole card ['D5', 'HA'], current stack 100
player [G7Player] gets hole card ['CQ', 'D7'], current stack 100

Street "river" started. (community card = ['DQ', 'DJ', 'D9', 'CK', 'D6'])
"['SixPlayer']" won the round 1 (stack = {'SixPlayer': 720, 'G9Player': 0, 'G5Player': 0, 'HonestPlayer': 100, 'OurPlayer': 0, 'MyPokerPlayer': 0, 'RitzPlayer': 0, 'G3Player': 80, 'G7Player': 0})

Apparently, G7 shall win the game, because it has FLUSH with "D7", but SixPlayer has FLUSH with "D5". The result is wrong.

Root cause

See here:

The flush can not be simply represented with only the max_rank_card. In fact, we need to compare these cards one by one.

In the issue we encountered, the flush was wrongly judged as the same for both G6 and G7, and then went to the 2nd bug (mentioned here), comparing the hole card, which results in G6 as the winner.

How to fix

We have to change how the "score" is represented for FLUSH. It shall contain 5 cards, instead of only 2.

# [Bit flg of hand][rank1(4bit)][rank2(4bit)]
# shall be:
# [Bit flg of hand][rank1(4bit)][rank2(4bit)][rank3(4bit)][rank4(4bit)][rank5(4bit)]

Enable start_poker command after pip install PyPokerEngine

ex. virtualenv

Kota-no-MacBook-Air:~ kota$pip install virtualenv
Kota-no-MacBook-Air:~ kota$ virtualenv  // <-virtualenv executable script is added on PATH
You must provide a DEST_DIR
Usage: virtualenv [OPTIONS] DEST_DIR

Options:
...

HOW TO DO

Add script/start_pokerpath asentry_points in setup.py

I work right now on a solution for my other problem and found this issue in your code too.

Wright me if you want to see my solution. I can come with a full solution for the hand evaluator ;)
