one of those spots where 4b/f looks decent.
Again, I might get hate, but I see no reason to call off a jam. It'd be roughly breakeven call (at best) if we were 100bb deep, those additional 9bb only worsen our price=>ev, since we're most likely behind his jamming range.

Yet I dont wanna flat for obvious reasons and we do have blockers and stuff.

So yeah, 21bb/f imho.

4bet gii vs SB and fold vs MP imo

+1 to 4bet/folding here.
