Mike Matusow is one of the best poker players in the world and has won millions of dollars playing poker. He almost won the 2005 WSOP Main event but his trip Kings lost to a nut flush. Had he won that hand it is highly likely he would have won the Main Event. Sometimes he acts what people would call strange but many geniuses also act strange. The great American Chess Champion Bobby Fischer often acted in a very bizarre manner but was a genius never the less. I think Matusow is a genius and more or less the poker world's version of Bobby Fischer.
