33,,,,'Crabs' is the name for the starting hand 3-3 (also known as trip three's, treys or pocket 3's). It's not the greatest starting hand however as with any pair, you will hit your set about 1 in 8 times the hand is played. The problem with 3's is that you really need to hit one of the remaining two 3's, as there is little chance that you won't be facing over cards on the flop.
