22 is only good for sets. I guess that's pretty obvious though.

Sets makem the big bucks v. average players; when "seasoned donks" look at a flop, the idea of a pocket pair is the last thing to come to mind (which makes them vulnearble to sets/ overpairs.

Because of that, 22's generally good to see a flop (given he's got enough chips left to make your gamble / chase worthwhile).

One thing I hardly understand is when people push allin with 22. (because a pocket pair's a slight "favorite" v. overs. *note, 22 is dog to suited / connecting overs, lmao*) Fold equity? If that's the reason, why not push any two?

22's a good push if you have 5 blinds, or are otherwise either eating **** in terms of chip count. Otherwise, nah. It's a drawing / implied odds hand all the way. As such, only play it during deep-stack, post-flop heavy poker. Cash / early (speculative) stage of tourney, prob. never folding 22 unless someone shoots their load with a *monster* raise. (and even then, if they have enough...). Late tourney, I'm dumping this one along with 89suited, etc. Late tourney = paint time.
