Villain is a regular at 3/6 and 2/4, I haven't seen him much at 5/10. He's running 23/20/3.6, 3-bets 7.3% (above average, nothing crazy) and folds to cbets 63% (def above average). My notes say he might think I'm a bluffer, but my notes on the specific hand are sketchy. Looks like I might have c/r bluffed him on a two-tone flop and shoved the turn flush, which it turned out he had. A couple orbits earlier he shoved QQ over my oop 4bet and I called with AKs and didn't get there. He typed "first flip I've won in two weeks" and I typed "15th flip I've lost in two days". He also typed that he had started drinking and that accounted for his luck changing.

Obviously folding is safe and easy but it seems so exploitable given how wide my range is in this spot...
