The $2/$5 maniac who checks the flop in position after calling your raise is not giving up. He's floating to take the pot away on a later street. Don't barrel him off without a plan.

Why they do it

$2/$5 maniacs are more disciplined than $1/$2 maniacs. A flop check in position from this player type after calling preflop is a read - he's waiting to see if you show weakness on the turn. If you check back he's taking it. If you bet he'll decide based on his hand.

The adjustment

Bet the turn with conviction when you have something. Check back the turn with air when he checked the flop - don't fire into a float. He's coming for the pot on the turn and you're handing it to him.

What it's worth

Double barreling with air into a $2/$5 maniac who checked the flop in position and getting raised off your hand costs you two bets. Check back and save the second bullet.
