It's a bad bluff if, in the state of metagame we were in, he thought that I thought he would turn a hand into a bluff. Obviously he did not think this, and thought I would bet/fold one pair hands, maybe even some junk 2 pairs. Obviously this was not the case, given that I actually snap called here, and planned to bet/call prior. I mentioned in the OP that he HAD to be fed up with my barreling, as he was constantly folding, and I felt he would take a stand here. He had 65o fwiw.
