Brian, your post made me think, and it's true, I do hate to lose in general.
I can take it too far sometimes.
During graduate school, I played tennis over three straight summers with one of my fellow students, a good friend. I was better at tennis than he was. He had a nasty serve and some good power, but some very exploitable weaknesses. I think we played 2-3 sets per time, 2-3 times per week, probably 15-20 weeks per year for 3 years. So that's maybe 200 sets of tennis, minimum? I won every single set. And when he got close to taking one from me, I really swore at myself, hunkered down, played hard, hit my best shot at his weakest point, and just generally made damn sure I won the key point or points. I was completely in the zone where I refused to lose. Even once! (He beat me at other games, especially Madden 98 for Playstation.

)
Anyway. I did get back and play some more poker early this evening. I had a pretty rough time on the tables with a couple of suckouts, and couldn't lay down two hands I should have that cost me a bunch. And some tricky players made some tricky plays at me, which always pisses me off. But I finished up about half a buy-in overall. So I feel pretty good.
Played with suhleafs for the first time tonight. He very graciously took money from other people at the table but not from me. Except when I insisted he take a couple of bucks, one hand.
I guess poker is all about results for me, still. It shouldn't be but it is.
Thanks for the feedback, everybody.
