Hero UTG 33 (Covers table)

Hero raises to 12.5
3 callers

Flop A35r

Lag x Hero bets 30 into 50 pot rest folds Lag 3-bets to 110. He started the hand with 500. Reads on LAG an AGGRESIVE live player I have seen him call down quite light and he also is not afraid to put chips in the middle. Always buys in for maximum, havent played enough to know if he is good or just spewy.

Turn 6 making a fd

Lag X Hero?

Well whats the best way to go here? Should I x back on the turn repping a scared ace that wanna get a free sd? The turn should help him
quite alot since I think he will make this move with 54/4x or maybe just 67. He could also have an ace here and find out where he stands. Anyway is my call on flop good or can I reraise seems on that dry board he will only give action with 2pairs and money is going in on the turn then anyways better keep his bluffs in? But still his x on the turn seems kinda weak so probably he was just bluffing and gave up?
