Who Is Mark Kratz?

[RPatterson]

I played with him a bit at full tilt, what hands was he involved with on ESPN? Is he a pro?

another question:

there is a guy on full tily right now playing $1/2 limit with the username "Joey", I can only assume this is "Joey Clapper" who had $13,900 chips at the end of the day 1 in the WSOP
