Hello Community,

I am currently stuck at the understanding of unsafe subgame solving. I understand that each player is maintaining a opponent hand distribution. But how do I build the subgame to solve or how do I use these distributions?

For example sample a pair of cards for the opponent and take the ai cards and maybe already revealed public cards to do CFR with?

Does someone knows how unsafe subgame solving works in detail?

Thanks

If you haven't already done so I suggest you implement CFR for a very simple poker like game. There is some code on this site somewhere for you to copy.

At the beginning of the game both players are assumed to have an equal probability of holding all the hands that are not excluded by the opponent's actual hand.

At the beginning of a subgame both players are assumed to be holding some distribution, but apart from that the approach is the same as playing the entire game.

If you haven't done so already take a look at Noam Browns NIPs 17 lecture on YouTube
