I'd put the villain on QQ or JJ almost certainly, possibly AK but less likely. Was representing A's.

I know it's a very risky play but I was trusting my read of both the opponent being fairly tight and his cards [img]/images/graemlins/smile.gif[/img]

Is this a valid play I should use every now and then or something that is way way -EV?
