I'm currently developing a poker bot that plays online by itself in zoom poker and I'm looking at optimising the strategy.
So far I've noticed that setting an investment limit based on equity is more successful than EV. For example I set the call or bet limit to equity^4 +0.04. If the big blind is $0.02 and initial pot size of $2.00. So to invest $1 I would need 100% probability to win. For turn flop and river I then power the equity by a different number, which makes the criteria more or less stringent.
However it seems this strategy is still too simple. In your view, what are the key parts missing? General, is it better to play more or less aggressive pre or post flop?
