This might look stupid when you look at the hh :D

5 handed in blind stealing battle, he could have AK here like 40% of the time, no?

call to set mine then fold if miss, or get it in preflop, depending on what hands you put him on.

also, if you think he has KK, why risk turning QQ into a bluff?

well given that its early in the session he likely has alot of air in his 3bet range but isnt going to jam light over your 4bet so flatting pre seems optimal. (going off a general assumption here that most tags are looking to get their first 3bet out of the way early...its pretty much true just 4bet the first time someone 3bets you always and see how often they fold)
