Nope, the only high-stakes heads-up players I know are pros.
I'm having an ongoing problem with these fuckers stealing my name. At the bash, MonkeyFOcker told me that he read an article about me. I was pretty surprised, since I hadn't been interviewed or anything. It turns out that some supposed professional sports-bettor was going by Mr. X and it wasn't me. I guess this is what you have to deal with when you have a 1-letter last name.
As an aside, even though I played for a living for almost ten years, I am a big-time poker wimp when it comes to stakes. I think a $325K win would would be about 100 times greater than my biggest score.
