In multiway pots you can lead out with Top pair…so bet call a shove
The problem with u shoving over a C bet is that ur not called my worse….mostly when u shove a 40+ BB stack and are called he will have a over pair or a set or a strong draw with live overs etc. So ur in a situation where u win a small pot with ur shove or loose ur stack
as played id flat the flop to keep worse hands in his range…anyway i agree with antilog we r out of position after all so id either squeeze with this hand and 22 bbs but most likely since its an early position raise and a hoodflat id let it go i think and wait for a better spot
