UTG calls t120 <font color="aaaaaa">(pot was t180)</font>, 3 folds, SB calls t60 <font color="aaaaaa">(pot was t300)</font>, Hero checks.

SB checks, <font color="#cc0000">Hero bets t220</font>, <font color="#cc0000">UTG raises all-in t1550</font>, SB folds, Hero?

The villain is a loose donk who has been limping/raising a fair amount. Call or fold?
