NL100 AKo 4bets against maniac player
 

This player was playing like a maniac, never could put him on a real hand or range. A couple hands bevor this hand, I stacked some one with Kings and won from him a good amount with AQs, so obviously they should know I´m on a run. He min3bets me and I decided to 4bet, because he 3bettet every PP and any Ace with acceptable kicker.

I'd bet like $25 on the flop, if called, take a free one on the turn if it bricks.

I bet the flop a lot. Checking isn't terrible but this seems like the kind of guy that'll bluff every turn if you check behind, so if you're not comfortable calling a large turn bet with A high then I'd just bet 30 on the flop and take a free card on the turn

Betting 25 gets him to fold roughly 0% of the time. It just looks a little too weak. Betting this flop is crucial though, i'd say at least 30, and give up if you get called/don't hit a straight on the turn.
