$1-$2 9-handed home game.
Hero: Known to be a winning player...but tighter, frustrated image this session as I've been card dead and playing snug. Relative history - 30 min ago, raised light on button to $11, quickly laid down to $35 3-bet from SB nitty player. $305.
Villain: Winning player, thinking, more TAG than LAG. We've played a lot together, but not many heads up pots as we both know enough to stay away from each other. $280.
