In the previous post, we considered the probabilities of making one specific hand with the turn/river card. This can be rather useful in specific situations, but still cannot apply thoughout a game. Poker is essentially an incomplete information game. Different from Go, where you can see all stones placed on the chessboard and thereby "solve" an optimal move, you never know you opponents' pocket cards until showdown (yet even then, people mucks). Also, you have little clue on the unshown community cards. Therefore, in order to evaluate a hand during a poker game, we'd better opt for a online evaluation algorithm instead of considering this as a DP-like problem.
