Just sat down recently, was within the first two orbits I believe, so no stats. Obviously, with his 3bet/call PF, I was thinking JJ+, AK. If this truly is his range, I think I should be checking this flop and see what he does with it, and also to allow his JJ/QQ to make a play at it. I think by betting I blow all of that out of the water and leave KK/AK in it, which obviously crush us on this board. Thoughts?

Also, I seriously think that my bet/bet line is probably the most -EV play, unless I have history that shows he calls down with a smaller PP here, which I obviously don't. My question is what would better line be? c/c, c/r? c/c lead? c/r? b/f? (although I don't see how b/f could be an option as our SPR is ~1.5, so any bet more than commits us.
