Pot is almost $11 and I have to call $2.20... I think I'm probably behind to KK+ or a set though... This guy hasnt played many hands... Can I fold or is this a must call? Theres always the possibility of 99-JJ too... but I think that is slightly unlikely considering I re-raised preflop.

No, you can't fold. You'd have to be 85% certain that he had 55, 66, 77, KK or AA to justify it, but he could just as easily have 88, 99, TT, JJ or even an OESD. In fact, you're lucky that he has such a small stack because it makes your decision for you - if he had pushed a full stack in you'd have a lot more of a dilemma.

Well I was probably 75-80% sure I guess my call was good then heh

This might be the easiest call of all time.

$2 to win $10? CAAAALLLL!!!!
