PS 27 turbo HU float then bluff

[elcheapo]

Villian is a multitabler who I decided from betting patterns that his hand was not very strong . I had also let him have 2 previous pots uncontested. I didn't even think he was drawing.

PokerStars Tournament, Big Blind is t400 with t25 antes (2 handed) Converter on pregopoker.com

Hero (t6925)
BB (t6575)

Preflop: Hero is in Button with 7[img]/images/graemlins/club.gif[/img] Q[img]/images/graemlins/club.gif[/img]
