Draw by stalemate

[lrozenblyum]

5.2 a) The game is drawn when the player to move has no legal move and his king is not
in check. The game is said to end in ‘stalemate’. This immediately ends the game,
provided that the move producing the stalemate position was in accordance with
Article 3 and Articles 4.2 – 4.7.

Informing Winboard about state should be done according to the rule:

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}
