villain here is Schemeny, a 200nl reg. he runs about 14.5/12.5/4.5 over a good sample. i actually dont have any specific reads on him. original raiser is some fish that raises 7% of his hands. i cant really put schemeny on anything but a bluff or 22, all of which i beat. also i dont think he is slow playing two streets with a set. but like, it is such a freaking bad spot to bluff. he never has KK, and i think he wouldve c/r me on the flop with a FD. the only 6 in his range could be 66, and he easily folds this on flop or the turn.

my hand looks like a K, draw, or set. im never barreling here with A high, and i would imagine villain knows that at least. anyways, thoughts? can we ever muck?
