In any case, I explained the rules of the game to Dojo, and he agreed to 
give it a try. We went down to the nearest mud flat, and there, in plain view 
of many shrews, I played a game of tic-tac-toe with Dojo and vanquished him, 
although I will confess it was touch-and-go for a while. It was done; I had 
defeated Dojo in single combat.
