How would you have played this maniac?

Ok I'm sitting with this guy who is just a huge maniac and I played two hands against him after which he left. Here's what happened:

First hand I have QQ, I raise preflop and he reraises me. Everyone folds and I call (HU).

Flop comes 10 4 x, he bets, I raise, he reraises, I cap, he calls. Turn comes a 10 and he bets again, I get scared and just call. River is a 4 and he bets, I call. He turns over 45o for the full house and takes the pot.

Exactly two hands after that, I get KK. I raise and he reraises me again, I cap, he calls. Flop comes 10 3 x. We both cap the flop. The turn is another 10...we cap again. River is a blank and we cap. He turns over 10 3 for the full house and takes the pot.

I really don't know how to play against guys like that...any advice would be appreciated.

Looks like he's just getting really lucky. I think capping the turn and river on the KK hand was a bit over-ambitious though. Maniacs make tons and tons of mistakes, so you can grind them away more cautiously, rather than in big hands where they might wake up with a real hand.

In general, just keep playing aggressively with decent hands. If he caps every street with both great hands and with trash, he's eventually going to lose money because there's far more bad hands than good ones.
