Final Pot: 11.00 BB


Ignore the pre-flop raise. I tend to get a little antsy on my last hand when I get dealt something mediocre.

Button had been getting out of line all session, he started trying to blind steal like mad and got caught with 36o with a flop of 33K. He had been running pretty well and was generally agressive.

Button was 73/28/1.62

I bet out on the flop because the pot was pretty big, and the button was a spaz so I hoped he raised to kick the SB out. What do you think?
