In addition to NFSP’s main, average strategy profile we also evaluated the best response and greedy-average strategies, which deterministically choose actions that maximise the predicted ac- tion values or probabilities respectively. It is played with a deck of six cards, comprising two suits of three ranks each (often the king, queen, and jack - in our implementation, the ace, king, and queen).

We perform numerical experiments on scaled-up variants of Leduc hold’em , a poker game that has become a standard benchmark in the EFG-solving community, as well as a security-inspired attacker/defender game played on a graph. You should see 100 hands played, and at the end, the cumulative winnings of the players. We present experiments in no-limit Leduc Hold’em and no-limit Texas Hold’em to optimize bet sizing. This code yields decent results on simpler environments like Connect Four, while more difficult environments such as Chess or Hanabi will likely take much more training time and hyperparameter tuning.
