4Bet or call with AK?

The first spot is definitely much tougher than the 2nd flop. You're having to go in cold to a hand with a raise and 3bet, both players having uncapped ranges. I would probably be inclined to call/fold in situation 1 and 4 bet in situation 2. In situation 1 you have a positional advantage, but UTG and MP ranges are likely very tight and skew towards premium hands. In situation 2, they are later position so their ranges are wider. You are also out of position so it's tougher to play postflop, a cold 4 bet also puts anything but premium hands in a very difficult position to continue.

(6x - its a 12bb? Just dont understand 6x from bb or from openraise)
If 12bb
The first you must fold ))) Free position vs hard ranges of opponents.
The second you must chose beetwen 4bet and cold-call+call only one all-in.

this is Zoom, im actually thinking that im inclined to fold here, 3x the bb was deserving of a call or reraise if no other action, but with the other raise, you cant really call, if your calling your looking for a VERY strong hand as i stated its Zoom, your not going to get people calling with worse very often, so if you have to hit that hard there is no point wasting 6 or even 12bb especially since we dont know if the UTG will reraise, its only my opinion but i dont think we have the odds to see a flop in this situation

The one thing you kind of have to take away from this, is AK is not a made hand. It is not AA or KK. The only time AK has a ton of value is on the final table with 5 or less people left.

Nl zoom cash plays very tight. Id still 4bet each of these to 16bb and 18bb.
