4betting 2.5 times villain's 3bet is sexy when you have position, and it can be neatly balanced between occasional bluffs and things you will stack to a shove. Mostly because flatting the 4bet oop will suck for villain, so he has to fold or shove.
Out of position, i like to make my raise a little overpot sized, and that would mean a committing raise here, so 4bet shoving is fine. No real need to balance that until people decide to call with small pocket pairs because they put you squarely on AK. Then you can start 4bet shoving AA too.
As played, i like check-folding this flop.
