UTG folds, UTG+1 folds, MP1 folds, MP2 folds, MP3 folds, CO folds, Button raises, Hero 3-bets, BB folds, Button calls.

Hero bets, Button raises, Hero calls.

Turn: (5.50 BB) 5/images/graemlins/spade.gif <font color="blue">(2 players) </font>
Hero checks, Button bets, Hero raises, Button calls.

River: (9.50 BB) J/images/graemlins/spade.gif <font color="blue">(2 players) </font>
Hero bets, Button calls.

Final Pot: 11.50 BB

I think for sure the turn raise was bad which would have saved 1 BB. Is this check call the entire way? I think this player is capable of stealing with any hand and would bet with nothing.

uh for starters preflop. You need to find better spots here than with ace rag especially in heavily raked LL games. If this guy is a total maniac or someone you know will ASB 100% of the time then your play is fine other than the ridiculous turn check raise.
