I'd cbet the flop as I don't think we'll win that often at showdown checking back and we can't really call a bet if they donk the turn.

I like the 3bet, 50bb stack we don't really get set value with 22s, and they have a high f3b%.

Pre: I would be more inclined to just fold this when stacks are shallow rather than three bet.

Flop: It's going to be close here between c-betting and not, when we check we are essentially waving the white flag and letting villain know they can take down this pot. I would lean towards firing a small c-bet hoping to take it down, and not planning on investing any further chips if called.

Turn: As played I fold here too, it is going to be very hard to turn a profit on this kind of board with 22.

Not a fan of pre, just fold against the short stack.

Flop check is good as played.

Folding turn is good as well. If villain checks we can consider bluffing turn and river to get him off better pocket pairs and protecting ourself from getting bluffed by whiffed Ax etc.
