[Fictive]

Post flop I don't see a problem with the play, especially given the fact that you had some reads on him.

However, no matter what position, with AK you ALWAYS must punish limpers. Most likely the hand would've gone: shadylady limps in, you raise (for example 3-4xBB), Dalton folds BB, shadylady probably calls. You hit top pair top kicker on the flop, throw in a pot-sized bet, or an overbet. I doubt that shadylady would have called with second pair decent kicker+gutshot. If she did you were in a weird position, but still likely to have the best of it. Turn card is a rag, push all in. If you still would've been called, then there's nothing left to do. If shady is a fish or no, you still would've put all your chips in with the best of it and you would've been the fav to win the hand. (Flop 68%, turn 80%).
