Now, this is interesting :D

21/16, 3bet: 5% after 700 hands, seems reasonable and not spewy
MP & CO - 1tablers, semi-regs/fishes, but not really crazy. 34/24 and 17/5

So, im calling preflop because
1) we are at deep stacks w/ raiser
2) weaker players behind me that are likely to get into pot with much weaker range.

Postflop?
Even if its a bit silly, but i think that folding flop there vs. his sizing is not that bad idea. Still some AQ at some frequency in his range maybe, so called.
But really doubt he's going for stacks 160bb deep there with Qx, im propably facing there AA/QQ too often to call.

Thoughts on flop&turn play? Or maybe even preflop? I think preflop i would 4bet there with AA, stacking off KK would be propably still EV+, but not in love with this play, especially if his 3bet is so tight.
