pot 4bet imo to $28.50 I think it will be, if he repots it'll be $78 I think? In which case he almost certainly has AA, so the shrewdest move imo, would be to flat here then if the flop is really gross we can chk.fold.
Pot will be $157.50 OTF and there will be like $82~ back in stacks so we really dont need very much at all to stack off, anything open ended straight draw+ also a gut-shot and 2BD FD's prolly just about enough if the gut shot include a TEN.
Also never fold this hand preflop unless it's you've 7bet and the 8bet require you to risk the life of a small child/loved one. the reason we can't 4bet fold is that once we 4bet and he 5bets we are calling $50 into a pot of $150~
Player,Equity,Wins Hi,Ties Hi
AhKhQdJd, 34.5775%,34.1485%,0.8582%
AA**, 65.4225%,64.9934%,0.8582%
Plus the implied odds should we hit our flop - we will be calling $82 to win $321.50 (assuming ofc he never folds, which is safe enough) so we need 25% equity to call off OTF.

Which as you we will have 60%~ of the time.
Easy!
