Hands vs. A Maniac

Still adjusting to NL. The maniacs are much more brutal here than they are in limit.

One off-topic question as well: Im running 19/12, going to showdown 21% of the time, and winning 46% of the time. Seems pretty poor winrate for only showing down 21% of the time. What's a typical WTSD and W$SD for 6max NL.

Villian is UTG and a complete maniac. 92/75/3.

1) Call, I guess - he's a maniac... and check call any river unless you think he'll call a raise with QT-QK. Raising probably only folds hands you beat and get's called when you're behind.

2) Fold, what could you possibly be ahead of? You're either WAY behind or barely ahead. Oh, and please make your standard Cbet 2/3 - 3/4 pot. Betting less than half the pot lets people play back at weakness, even at $10NL.

1) I would raise the flop but not the turn, and I always check the river to these types of players because they love bluffing the river with complete air.
