Subject: Draws in general

A special note on draws (FIDE rules), FYI.

A stalemate is always a draw (even if illegal moves are made afterwards).

Insufficient winning material for both sides is always a draw. If one side has
insufficient winning material and his opponent's flag falls, then it is a draw,
not a win.

If both flags fall and it is impossible to determine which flag fell first, the
game is always drawn.

Draws by repetition of position and by the 50 move rule are only draws if it is
claimed by one person. If the draw is missed (or not claimed) and the game is
continued, then the earlier draw cannot be claimed later in the game (although
later conditions can turn the game into a draw again such as the 50 moves
extending to 55 moves).

Most of these will not be an issue with computer programs, however, it is
important to note that draws by repetition of position and the 50 move rule DO
NOT have to be claimed, so programs should be written to not bring it up if they
think they are substantially winning (if their opponent does not catch it, too
bad).
