If your opponent eliminates all your options to move, you don't lose in chess, but is regarded an equal to your opponent. Isn't this peculiar? In most games and in real life hunt and war it is a winning strategy to eliminate the opponent's options to move. "Oh, you can't move now, can you, so it's obviously my turn again! (grinning)"
Is there some history to this? Stalemate does make chess much more interesting, but was it kind of invented in order to be so, or how could it have evolved? Is there some Victorian age gentlemanship involved here?
