Kaz, a c/r isn't for value, it's as a bluff and as weird as it sounds it might be +EV.
Corsakh: Don't wanna hijack the thread, but screwing with a TAGs cbets from position is pretty profitable. Floating, bluffraising flops, semibluffing, and who knows we might even hit top pair! RIO are mitigated because we're in position. I think that you're way off on 3bet or folding KQs and QJs preflop. I mean, KQs is certainly fine for a 3bet from CO vs Btn, but it's also very +EV to coldcall.
I know that in this example hero is OOP, but most of the points about where the value of hands like QJs comes from still apply. This is the classic samoleous versus EM2 thread that I found really helpful in my understanding of play in 3bet pots.
