ok... i saw from earlier hands that this guy was pretty crazy... basically raising w/ anything... mid pair... etc...

i lost a lot on this hand (10.5 BB) so i was wondering if i played this too agressively... any comments?

Why did you slow down on the turn if you were going to cap the river? I think I would have slowed down when you did on the turn but I would have check/called the river myself.

Oh, btw, don't post the results as it can affect people's opinions of how you should procede.

If he's a maniac I think you should cap preflop without a question.

I like your flop and turn play. But unless he's the most outstanding maniac you've seen in a while I think I'd just check-call the river. I'm taking it to showdown no matter what, but unfortunatly somtimes maniacs also get good hands.
