I'm having this very problem as I type this post. I'm sitting here at a NL table with a complete and utter maniac and I can't seem to catch a hand when he's going after pots. The one hand where I turn the ace high flush, he checks it down and folds to my small river bet.

This is driving me insane. You basically need any pair to beat this guy. He's one of those "raise preflop then all in on the flop" kinda guys. He's trying to win every hand, but I can't seem to catch a hand worth playing to try and double up on him.

And what makes this table even jucier is the fact that everyone has started playing back at him, making some very large pots.
