JJ as an overpair

[rikz]

Most of the replies to this post advocate re-raising preflop with JJ.

What is the range of hands that hero should reraise here in the cutoff given an open raise from UTG to 4xbb in 6 Max NL $50, as shown in this hand? And why?

Given that range of hands, what do you fold to a 3-bet given no real reads on villain yet, as shown in this hand?

I would have reraised: AA, KK, QQ.

Obviously most of you guys reraise JJ. What about AK, TT, AQ(s), 99, 88, 77, lower pairs, AJ(s), AT(s), KQ/KJ, etc?

I mostly play full ring, and a big re-raise preflop full ring is almost always AA or KK. Occasionally, I'll see a guy with AK do it, but if he gets a 3-bet from the original raiser, he is almost always up against AA or KK.

But 6-max is obviously different, so how different?
