My problem when playing poker is that I get rattled by idiots. I played a small tourny in Vegas a few years back and there was this idiot at my table who thought he was Phil Helmuth. I was happy to take his money but my focus was shot. Especially when he pulled a Helmuth and cussed me out for knocking him off with what he considered a lame hand(I had J/Q suited. If that's considered lame then I don't know what's good).
