Villain has 80BB stack. Blinds are $0.12/$0.25.

Me: :Ah: :Ad:

Preflop: UTG (danci) limps, folds to me on CO, I raise the pot (4BB), villain calls UTG calls.

Flop (Board: , , ):
danci: Check
_Vrax_: Bet 2.75
DR_DPE1: Call 2.75
danci: Fold

Turn:

_Vrax_: Bet 6.25
DR_DPE1: All in ($14)
_Vrax_: Fold

I'm not sure of my turn bet. What do you think about the turn bet, isn't it too big?
