actually I like the river fold, I don't see what he's valuebetting worse and it's hard to believe you were floated then double-barreled in a 3bet pot deep.

I'd just b/f turn and then probably c/f or c/c river depending on how I felt.

Also, I hate PF sizing, just too much, 3bet wider so you don't have to blow players out of pots with your big hands.
