Countering a ultra-loose passive slowplayer?
What do I do vs someone like this? I recently played a person like this in a casino. When my hand is very strong it's very easy to trap this person. But when my hand is less clear-cut I never know quite where I stand.
Let's say I raise in late position with A-Q of hearts. The flop comes down A 5 6 with two spades. He checks, I bet the pot, everyone else folds, he calls. The turn comes an 8. He checks again. What do I do here? Do I bet my top pair again?
Probably he has something dumb, like A-3, but he could also have A-6, A-5, a set, a flush draw, a straight draw. He isn't quite a complete calling card- he is somewhat capable of folding. He will have either some kind of draw, or he will have a hand. He could even be slowplaying a KK or AA, this is exactly what he does, I saw it twice. But it's so difficult to define his hand because he doesn't raise, and he does sometimes make poor chases.
So in this situation, should I just value bet everything, and not worry if he is slowplaying a bigger hand since he's never going to shove me all in? How then do I take all his chips? What would you do?
