Had a hand almost exactly like this and I was up against AA Had a lot more reads though and villain got tricky cold calling my 4 bet Because he knew I was strong

OOP I'm 4betting around 2.5x. Otherwise v gets good odds to call IP. so around $2.20
If you've made up your mind to GII, then as played I'd either check jam flop or check raise flop & jam turn. You've got a pot size bet on turn so just jam
But since your 4bet is a bit too small could run into something like ATs,JTs of course
