Last weekend at a home game with my friends I went on tilt. I got QQ and made a call against a friend on an 4 6 9 J board with a flush draw. My friend shoved and after a lot of time guessing what he had i determined he was bluffing. I call and he turns over A 4. I'm in a good position and the only cards that can beat me is an ace or a 4. Of course the river is an ace, and i lose about 50% of my stack. My play suffered the rest of the night
