AK in 4bet pot

I'm not sure we can stack off preflop with AKo vs 19/12 guy, so maybe we could just flat. If we do 4bet, we could do it a bit smaller, like $1. As played, flop cbet size in 4bet pots should be smaller, like 1/3. I wouldn't cbet, though. I don't see better hands folding nor worse hand calling. I think we can check back the flop and start betting or raising T and R only if we hit TP.

Hand sample is too small.
AK is a default stack off.

I think we can 4bet and stack off with AK from the blinds.
I wouldn't cbet that flop.

I am most definitely not calling that flop check-raise. I might make one (last) stab on the flop to keep the game simple (i.e. to avoid hard guess work on the later streets), but this is not a go-broke situation. We have an unimproved A high and an angry opponent.
