	LOL! However the illegal move didn't affect the final result of the game. I find it doubly amusing when an illegal move leads to a result other than the correct one with best play. Arguably a more efficient route again was Nc2-e2!!, rerouting the knight to c3 whilst gaining a tempo on White's king.

You never guess what happened to me in my local Cup game tonight... played a illegal move in a time scramble Embarrassed

but my opponent did spot it however some of the spectators did see it. Gonna try and recreate it if I can after some sleep.

Manage to recreate it, here goes...

In the time scramble, White has just played Bg6 (from e8) attacking Black's knight on c2. Seen as it's being attacked, my thinking was to get the knight to c3 as my next plan attacking the white pawns on a4 & b5. There was the efficient route via e3 or the scenic one via a1 and decided to shortcut via a2??!! Embarrassed

	In the future we'll all be playing on electronic boards and if an illegal move happens an alarm will go off and a voice will say "YOU CAN NOT DO THAT. REPEAT CAN NOT DO THAT IDIOT".

Black was so shocked at missing this ingenious knight fork that he immediately resigned. @TN - Slight typo, was tired after my long intense game. Hahaha, loved to see the reaction of that opponents face when the knight moved to d7! I'm assuming the game officially ends when the opponent does actually resign and not say afterwards that's an illegal move. However I don't think that move can match the illegal move I played with my knight last night. Apparently, it moved from Nc2 to a2 within the scramble, lol.

	A friend of mine tried a similar Knight maneuvre in a junior tournament. Only thing was he did it on purpose and got away with it. Needless to say not behaviour to condone.

You mean that your opponent didn't see it right? Wink

While on the theme of illegal moves, here are two illegal moves, both of which went unnoticed by the opponent:

White played 54.Nf5-d7?!! here. Black was so shocked at missing this ingenious knight fork that he immediately resigned.

White played 32.Nf4-h2!!?, a very clever idea of playing Nf3-g5, except for the inconvenient fact that it is illegal. The game continued 32... Rb4 33. Nf3 Nh5 34. Ng5 Nf6 35. Ne6 and Black resigned. Both players denied the illegal move after the game until they were shown the position before Nf4-h2 after the game.

Do you think that this is a coincidence? Well, both games were played in the same tournament (albeit in different years). Grin

All our dreams come true if we have the courage to pursue them.

As for a database, there is no way to record illegal moves in it. Interesting, I didn't know that one either. Maybe someone should put in a request to Chessbase to have some sort of facility to help input these illegal moves into games in the near future. You can record illegal moves, but not in a single game. You need one game with the moves up to the position where the illegal move was played, and a second game with the position from the illegal move. Obviously game text explaining the illegal move in the game should be included to avoid confusion. I once made the same mistake in a rapid tournament where I tried to castle, realising my mistake as soon as I pressed the clock, but fortunately I was two pieces up anyway and the move I had to play, ...Kf8, was one of the best moves in the position.

Or does it apply someone inadvertently uses both hands to pick up both pieces simultaneously? I suspect it is using both hands as it's a separate rule to the one mentioning one hand. I mention this, because in our local league we have a player renowned for doing just this. He picks up both at the same time. Sometimes a small crowd gathers to see him castling!!

	Under FIDE rules, the position immediately before the illegal move is to be reinstated, as long as the illegal move is discovered during the game (section 7.4.a.).

	Stigma wrote on 01/30/11 at 13:09:10: Castling is defined as a king move in the FIDE rules. If Black has no legal move for the king, he is free to move any piece he wants. Unless he touched the rook first, which strictly speaking would give up the right to castle on that move even if castling were legal. Thanks for that, incidentally I was looking at the FIDE rules on this and the act of castling, quote :- 4.1 Each move must be made with one hand only. 4.4c If a player having the move intending to castle, touches the king or king and rook at the same time, but castling on that side is illegal, the player must make another legal move with his king (which may include castling on the other side). If the king has no legal move, the player is free to make any legal move ...isn't this rather odd for someone intending to castle, to touch both of these pieces at the same time with one hand? Or does it apply someone inadvertently uses both hands to pick up both pieces simultaneously?
