I love playing small pairs. When MP2 raised I nearly mucked because his stack was so small, but when Button called I decided to go along. Button has a good enough hand to call, but not good enough to re-raise. Hmmm...

Missed my set, but I have an interesting combo draw. Any three will give me a straight, either of the two remaining 6s will give me top set and any [img]/images/graemlins/club.gif[/img] will give me a small flush. Button's raise is big, but I figure I've got two cards to come, OK implied odds and lots of outs. MP2 might even come along for the ride if I call.

Hero checks, <font color="#CC3333">Button bets $3.85 (All-In)</font>, Hero...

MP2 got wet feet, and Button isn't backing off. Button's bet puts $8.45 in the pot and $3.85 is all I have left. I've got 10 outs but not all of them are clean, and if Button has a flush already then I'm cooked.

What's the play?
