[4_2_it]

I have no problem with calling him down after his 4-bet. I think he puts you all-in on the turn or certainly by the river. As long as fold isn't one of your options, I don't think you can misplay this hand after his 4-bet.

Villain's play is odd in that by 3-betting you let him know you weren't going anywhere and he only min-raises the 4-bet. Most villains with KK or TT are putting you all-in right here which is why I think you have reason to believe you are ahead.
