Very first hand at table, so no reads. I converted this by hand, so sorry for any mistakes. I'll reply with my own self-critique later.

Interpoker ($2/$4) 8 handed.

Preflop: Hero is MP2 with 4[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/spade.gif[/img]. Hero posts a blind of $2.
