Pre-flop: HockeyGuy folds. rudeboy calls. Shooterfirst folds. Spunky folds. YourDad folds. Mog calls. Ox folds. Rob calls. Kelly calls. HPDrifter checks. Ho hum. Suited low cards, free flop.

Flop (board: 3d 4s 7c): Kelly checks. HPDrifter bets $1.25. rudeboy folds. Mog folds. Rob raises to $2.50. Kelly folds. HPDrifter calls. Oh wow. Two pair on the flop. The button raised me the minimum - could have A7s, a set of 4's, 65. Rob hadn't shown me much, so I couldn't give him much credit for thinking about what I have. I had a sneaking suspicion I had the best hand, and if the turn doesn't appear to help him, I'm gonna push.
