I was a little confused on this hand as to what Villain had. His check on the turn made me think like he wasn't so sure if he was ahead anymore or he may have been bluffing the flop and decided to give up completely. My first instinct was that he had AQ. I thought he could be making this play with the Kd but how likely is it that he called that raise with a K? He could have had KK & been going for a limp re-raise and decided to cold call since it was already heads up but that is kind of unlikely. KQ usually fold here. I didn't think he would risk giving a free card here with a set or a small flush. Any help?Sorry I don't have the exact hand history so it's gonna be a little sloppy.1st Hand of Tournament.

What was the turn card, or do my glasses need cleaning. Assuming it was a blank I put him on A and a diamond and want to price him out of a flush draw.

oops. Yeah the turn was a brick. Do you push this then since any bet prices you in anyway?

No...a bet of about 400 prices out the flush draw but doesnt commit either of you. You still have half the starting stack if you think youre beat on the river.
