1) c\f the turn. EDIT: The GS makes it close but I still fold.
2) I don't hate against an aggressive player.
The only reason not to 3bet the flop is to c\r the turn.
EDIT: This is a standard play for me on a non-coordinated flop. This definitely does not qualify.
But if he's playing for a free card...I think 3betting the flop is best. Or calling the flop raise and donking a safe turn.
EDIT to also say: The way you played it, you can bet/fold this river.
3) If you're going to continue on the flop, I like the raise.
IMO. Just fold to the flop 3bet. Otherwise fine.
