Richard Schwartz has a long history in the WSOP with a bracelet from 1977 in his most successful game Razz. His nickname CK stands for Crazy Kid which is an epithet he gained as an action guy in the 1970's and has kept due to his large mouth. The way he kept talking and analyzing hands in the Razz event in 2003 made the clever and witty Daniel Negreanu ask for an exception from the "no headphones" rule.
