RESULT {COMMENT}
When your engine detects that the game has ended by rule, your engine must
output a line of the form "RESULT {comment}" (without the quotes), where RESULT
is a PGN result code (1-0, 0-1, or 1/2-1/2), and comment is the reason. Here "by
rule" means that the game is definitely over because of what happened on the
board. In normal chess, this includes checkmate, stalemate, triple repetition,
the 50 move rule, or insufficient material; it does not include loss on time or
the like. Examples:
0-1 {Black mates}
1-0 {White mates}
1/2-1/2 {Draw by repetition}
1/2-1/2 {Stalemate}
xboard relays the result to the user, the ICS, the other engine in Two Machines
mode, and the PGN save file as required.
