[Destined2Bgreat]

I was playing in a online tourney and after about an hour and a half i had about 14 big+little blinds in my stack and i was dealt 6 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/club.gif[/img] next to the button. With 3 limpers in front of me i decided to call so did the button and the small blind.

a half sized pot raise was made and called before it got me and i decided to push hard and try to win the pot right away with a raise the size of the new pot (4 times the original raise) aliitle more than half my stack. I was called by the button (who has a medium stack and has me covered)and everyone else folded.
The turn was the 2 [img]/images/graemlins/diamond.gif[/img]
I was recently transferred to the table and had no info on the button.
