big hand, big draw-bubble time

[tdarko]

50+5 MTT
top 9 pay, 11 players left

these are rough numbers and from memory so bare with me.

stacks:
Hero- 29K
CO-18K
Button- 32K (chip leader)

blinds are 200/400, Hero is UTG with A [img]/images/graemlins/club.gif[/img]A [img]/images/graemlins/spade.gif[/img] and raises to 2000, CO calls, Button calls.

flop (A [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/club.gif[/img])~6600
Hero bets 6500, CO calls, Button calls.

turn (A [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/club.gif[/img] 2 [img]/images/graemlins/club.gif[/img])~26100
