Small Stakes No-Limit Hold'em

You are right people call low flops with ace and king high, but this is a generalization. We have a specific opponent in this hand a nit (very tight). The nit would raise his premium hands pre-flop so probably he dosent have AK, AA, KK, QQ, JJ and usually these players don't call a c-bet with Ace or King high no matter what the flop is, they only know 2 board types one is when they hit top pair good kicker or better and one is when they dont and when they dont they fold. So on this board their most likely hand is a pocket pair, and pocket pairs dont like the turn overcard. The opponent is weak so we take advantage over his weakness by bluffing him to death.
