UTG folds, UTG+1 calls t30 <font color="aaaaaa">(pot was t45)</font>, 2 folds, Hero calls t30 <font color="aaaaaa">(pot was t75)</font>, SB folds, SB folds, <font color="#cc0000">BB raises all-in t1167</font>, <font color="#cc0000">UTG+1 calls all-in t1088</font>, Hero ???<font color="aaaaaa[/color">.

No reads as such yet,but I find that these shoves are 77-99 or similar a lot of the time,the guy who called in early position may think the same and have 2 broadway cards,can I turn down this chance to triple up?
