Here’s an interesting situation that came up recently. Players did not request a TD ruling, but we got discussing the incident at a party.
Players are using a chess set with a black king whose cross has broken off. White is a master, and Black is an expert. They’re playing totally book moves of a Semi-Slav. At the point where Black plays 13…Qb6 , he accidentally picks up the king with broken cross and moves it to b6. Before he lets go he notices that he picked up the king instead of the queen. He puts the king back on e1, and the opponent says “You have to move the king.” He doesn’t argue with the opponent, and makes a king move. It was clear his intent was to play Qb6. It was a book line where Qb6 is played at that point. Both players knew that was the move that is played there.
We were debating over whether the white player could claim that it was an accidental touch.
10B “a player on move who deliberately touches one or more pieces, in a manner that may reasonably be interpreted as the beginning of a move, must move or capture the first piece touched that can be moved or captured.”
Picking up a king can certainly be interpreted as the beginning of a move so it seems 10B covers that. But one of the people debating this said, “but it’s obvious that moving the king was not the intent since Ke1-b3 is not even legal, and it’s clear he was intending to play the book move Qb3.”
Could the director apply 10E?
10E “Accidental touch of a piece: A director who believes a player touched a piece by accident should not require the player to move that piece. For example , a player’s hand reaching across the board may inadvertently brush the top of a near by king or queen, or a player may hit a piece with an elbow.”
Based on the example it doesn’t seem like the director has the latitude to deny black’s touch move claim.
Though if I had been asked by the players to rule on it, I would have suggested that it would be gracious on White’s part if he withdrew the claim and allowed Black to play Qb3, since that was the intent. But I’m not sure I could compel White to do the gentlemanly thing to withdraw the claim.
