I just sat at the table but I played against this guy yesterday. He is a complete maniac. He bluffs too much and I've seen him play big pots with trash. He is a 25/10 though.

I know villain's calling range against my 3-bet is wide. He probably 4-bets AA/KK though, which should make them less likely holdings. His flop bet could be a bluff but it was big and I figured he was protecting his hand. If he did hit the flop in any way I don't think he is folding. What I'm wondering is, is there a better way of playing this hand considering I don't have a lot of fold equity here?
