Pre-flop: (8 players) Hero is CO with Q[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/club.gif[/img]
<font color="#cc0000">UTG raises to t160</font>, 2 folds, MP2 calls t160 <font color="aaaaaa">(pot was t220)</font>, <font color="#cc0000">Hero raises all-in t1125</font>.

No reads on UTG raiser and MP2 is somewhat loose. Having that in mind and the fact that the pot is almost 35% of my stack already, how do you like the push? Would you play it differently if you had 1500 to start with?
