Haven't been at the table long, I stacked a guy with a flopped flush. Villain in this hand has been pretty aggressive. Only hand we played, I raised from EP and he called in the BB and bet $15 into a $14.50 pot on a Ax7h8h flop. I folded and he showed KTo. I have folded to a couple of his pf raises from the SB since then so I am assuming he views me as weak tight.

Table has started to break up and we are down to 3 handed.
Stacks:
Me $360
Villain $580

I raise to $7 from the button with 99. SB folds and Villain calls.

Flop (Pot is $14.5): 623

He bets $15, I raise to $40. He calls.

Turn (Pot is $94.5): 3

He shoves (effectively betting about $310 into a $100 pot).
