Yesterday afternoon, on my way to gym (in which is my first session with my personal trainer, vomit half way but continue and still manage to finish the torturous drilling...Yes!) I was informed about a recent game incident at Unisza Open between Nabila and Ahmad Rizal Othman.
I did not witness what really happen. This is my understanding of what happen. Ahmad Rizal Othman checkmated (Take note. checkmated, not about to checkmate) Nabila but he has overstepped his time limit. Arbiter award the game to Nabila because Rizal has overstepped the time limit.
OK, I will do a little research on this since this is quite interesting. Both side got valid points.
Lets begin the research by consulting FIDE Law of Chess.
Article 5: The completion of the game
5.1 a.The game is won by the player who has checkmated his opponent’s king. This immediately ends the game, provided that the move producing the checkmate position was a legal move.
b.The game is won by the player whose opponent declares he resigns. This immediately ends the game.
Meaning, the game is complete (over) when player has checkmated his opponent king or one player has resigned, silent on overstep the time limit.
Of course we need to consult same clause at article 6 (Clock) as well to get clearer picture.
6.9 Except where one of the Articles: 5.1.a, 5.1.b, 5.2.a, 5.2.b, 5.2.c applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by the player. However, the game is drawn, if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves.
My understanding of this article is if player did not checkmate his opponent, or opponent did not resign or both player did not agree to a draw only then the game will be decide by the clock.
Based on above, i think arbiter has make a mistake. Ahmad Rizal should be declared as a winner of that game and not Nabila.
Few years ago Hairulov posted a similar article http://www.hairulovchessmaniac.com/2007/12/checkmate-or-lost-on-time.html
Based from his game against Julian Navaratnam, Hairul is one move from checkmating his opponent, overstepped his time limit but still arbiter award the point to Hairulov even though he practically has 'lost' on time. (Though i have different view on Hairul's case -he about to checkmate, not yet checkmated so basically i think Julian should be the winner when hairul overstepped...sorry Rul :) )
