got myself into a kind of interesting spot yesterday
playing $10/$20 at the Bellagio.
Fish Limps UTG, I Iso him from UTG3 to $120 with

(which I have been doing a LOT - with varying betsizes) playing ~$6,500
American guy, who I know played reasonable stakes online + has seemed to play really well 3bets from the C/O to $300 playing ~$5k, this is the first time he's 3bet me in about 80 minutes.
I call
Flop ($650)

I chk, he bets $380. I call
Turn ($1,410)

Thoughts on how best to proceed from here?
