I don’t want to pat myself on the back too much here, because (as I hope is obvious) I was trying to bluff him off of a better Ace. That said, the ability to turn a made hand into a bluff makes it tricky for your opponents to bluff catch against for two reasons. First, it is harder for them to read your hand. In a spot where it looks like I have either a monster or a marginal made hand but not a missed draw or something, some people will always fold their bluff catchers if they dont’ realize that I can turn the made hand into a bluff. The other benefit, illustrated here, is that it’s slightly harder to bluff-catch against you, since you may be bluffing with a hand that beats theirs anyway.

I imagine pokerjamers calls here because he assumes I will have a polarized betting range on all three streets. That is, I won’t bet a bare K on the flop, and I won’t bet a bare A on the turn. If that’s correct, then on the river I can basically have AA, KK, AK, or air. In truth, I make marginal bets like the one on the flop precisely so that I won’t turn my hand face up by checking back. (By the turn, I was already setting up the river bluff, not value betting). To be honest, I don’t mind his turn or river calls, but I think he probably needs to fold the flop. Granted he’s getting the right immediate odds to call, but it’s a spot where even if he is ahead, I’ll often take him off of the best hand by the river.
