The button has been opening with many hands in late postion but also makesloose calls sometimes.

I decide to move him in for an additonal 10k more. I know he will fold occationaly but if he calls I'm still most likely in pretty good shape because I have seen him make calls with some pretty inferrior hands earlier on, only to get lucking and win with them.

Result: He snap calls my all in but with A [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/club.gif[/img]

Unfortunatley he hit his ace on the flop, but hey thats poker.

1 2025
