I would not call this bet with two pair for the purpose of trying to hit a boat. He has four outs, plus some split outs, but being only 8 percent or so to hit the full house he would have to double up every single time he hit his full house to make the play profitable, and it's definitely a losing play to call here.

If the board pairs I would really hope that you don't pay him off. You might call a decent-sized bet, but I don't think he is going to win that much off of you even if he boats up. Would you double him up if he hit? I would hope not since you're at best splitting the pot. Besides, the pot is too small at this point to get all of EasyT's chips in on the river. He would have to overbet the pot all in, which should be a clear fold for you, even if you had an ace. Or he would have to bet and you would need to reraise him and then of course he reraises you all in, I would hope that you would never reraise him on the river after the board pairs. Calling this turn bet is a major -EV play IMHO.

As for your hand, I could see this being a total bluff a lot of times. Button raise means nothing, and after he checks with the four-card straight on the turn it brings up a great situation to bluff. This is another reason why it's a clear-fold for EasyT, there's a chance that even if he hits you have absolutely nothing and simply fold.
