No real read on Villain. New to these stakes. Question I have is on the turn, given the flop call. Check behind and fold the river to a big bet (and have 22 BB's left) if a club comes? Or overbet the turn and commit?

Blinds: $50/$100
9 players

Pre-flop: (9 players) hero is Button with Q/images/graemlins/club.gif Q/images/graemlins/heart.gif

You can't check the turn, villian like almost never has a 7 here and you cant give him a free card. Probably Call river.
