AK preflop

Billzfan86 3bets me light sometimes but we haven't played any relevant hands in months. Cold caller is a pretty bad donk 24/13/4 over 200 hands.

I like a fold.

Your UTG range is pretty tight, right? and MP2 must know this. If you know villain 3-bets you light sometimes then you probably have an idea of what sort of situations this happens in? Is it typically your lp opens rather than your UTG opens?

AK is at the top of your range here (guessing something like 99+,AQs+, 79s or something).
Cold-calls of 3-bets from bad players are usually AK/AQ/JJ+ type of hands.

Without the cold-call I'd go ahead and 4-bet. The cold call introduces the likelihood of blockers to your hand and that makes this far less comfortable. You're deep enough that villain is going to be calling a lot of 4-bets here and you're going to be playing the hand out of position. I guess you could call? I just don't like calling AK multi-way and oop that much.

I'd call, I can't see folding since you close the action and have position on the fish, also the presence of the fish means billzfan has to play more straightforward postflop.
