bet flop, lots of pair + straight draw possibilities(you also didn't mention what he does w/ TJ/QJ...wonder why? also even if you had his range right you want to c-betting 100% v this villain since he seems so weak tight and is probably never stabbing like ever. Giving someone free cards who isn't going to give us bets on later streets is pretty silly.

@ dona, your pretty much exactly right.

@ everyone who agreed with checking, do you seriously think a random 12/6 is gonna even give us one more bet on a board or KQT rather then try to get to showdown w/ some pair or even very likely just give up if he had like 87s.

@ shallam why do you want to pot control the turn when once he calls flop it's probably pair + straight draws...it would be better to bet flop, bet turn check river then to bet flop, check turn, bet river.
Also can you explain what a "controlled semibluff" is.
