SB: $10.60
Hero (BB): $12.75
UTG: $16.75 80/11/6
CO: $3.80 18/12
BTN: $10.65

Pre-Flop: T[img]/images/graemlins/spade.gif[/img] T[img]/images/graemlins/diamond.gif[/img] dealt to Hero (BB)
UTG calls $0.10, <font color="red">CO raises to $0.40</font>, 2 folds, Hero calls $0.30, UTG calls $0.30

I knew UTG would call and figured to bet if no overcards came on the flop.

Flop: ($1.25) 8[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/heart.gif[/img] 5[img]/images/graemlins/club.gif[/img] (3 Players)
<font color="red">Hero bets $0.75</font>, <font color="red">UTG raises to $1.50</font>, <font color="red">CO raises to $3.40 and is All-In</font>, Hero ?

I was planning on pushing UTG after his reraise, but then CO pushes. Calling is out of the question but do you fold or push?
