A river raise/fold to 3-bet - QTo

[Lurker4]

I tend to make this play when I'm the PFR, in position, am HU, bet the flop and am called, check behind the turn, and pair up on the river (usually top pair, sometimes 2nd pair). Of course its board texture and opponent dependent, but some opponents tend to bet out on the river and call a raise after the turn is checked through w/anything showdownable. I wasn't the PFR in this hand, but had the initiative on the flop/turn. Villian here is unknown.

Hand is from Full Tilt 5/10 6-max, converter doesnt work for FT so I'll just manually convert.
