During a hand a little while ago at the featured table, Doyle Brunson raised preflop but received no callers. He showed his and his tablemates smiled and laughed. As you probably know, Brunson won the WSOP Main Event in 1976 and 1977 holding the and has a strong affinity for the hand as a result.
In a hand just recently, Janno Cazemier raised to 900 from late position and was called by Steve Costello in the small blind while Brunson folded in the big blind. The flop came and Costello bet out 1,300. Cazemier thought for a minute before smiling and chuckling and revealing his to the table and tossing it into the muck.
Cazemier turned to Brunson and said "Hey, it works for you! I thought I'd try it. Plus, it was your blind!" Apparently the magic of the ten-two only works for Brunson, but it's nice to see the featured table having a little fun here on Day 1.
