AKo 4bet pot

14/12 is so nitty, that when he calls your 4bet and you don't hit your big boy, you're basically screwed. Not worth to fight back the guy OTF.
I don't know about you but I feel comfortable playing AK OOP. I like to 4bet when I know he folds too much.
But I think a call to his 3bet, even OOP, is fine in this situation. He is very nitty and you can attempt to steal the pot if he shows weakness, without letting it grow too much.
But obviously you have to play this mixed strategy: sometimes call, other times 4bet, so that you don't become so easily read (if this even matters on NL5, which is debatable).

Prefer just flatting pre and that's in 6 max from utg and mp but when it's 8/9 handed 4betting from those positions I expect becomes pretty undesirable.And with 1k hands vs a 14/12/4 villain I don't mind making a very exploitable fold preflop.Your vs an incredibly tight range and oop so I don't expect the ev of calling to be much better than folding.And I expect the ev of 4betting to be pretty bad.

4betting is a little bit to loose. Especially on a full ring table, but on the flop you can't do much else than folding.

Villain only fold 4bet 25, so thanks the comment, i had to call pre flop. I never folded AK against 3bet, even villain seems nitty. Only i thinked pre flop fold someone raise 3bet, if he 3bet range about 1 or less.
