Pythagoras: We discussed him on the backgammon board, too (Top 9 messages from the link). Some of his opponents don't realise the implications of the 11-hour-zero-bonus clock that he uses. Others think he's using that clock because he wants a fast game but discover that he stalls until they cannot stay at their computer. Then he moves and their clock runs out while they're asleep or at work. Strictly speaking it's legal but I consider him a cheat.
