Since I have no official connection with FIDE (except that I happen to have a FIDE rating), I’ll let someone else step forward with exact wording, if anybody cares to do so. Meanwhile, here is my idea.
First, a convenience rule. How many places in the FIDE rules is there a phrase like “unless there is no sequence of legal moves leading to the opponent checkmating the player”? A bunch, I would bet. One example would be in the rule regarding a time forfeit. Another would be in the rule specifying a cell phone penalty.
So why not have a definition, early in the rules, that would give a name to the concept? Such as:
- A position is win-excluded for a player if there does not exist a sequence of legal moves leading to the player checkmating the opponent.
- A position is a dead position if it is win-excluded for both players.
Then the various existing rules could be stated more simply and consistently. For example:
- As soon as a dead position arises, the game is drawn, regardless of whether either player’s time has expired.
- A player whose time has expired shall lose the game, unless the position is win-excluded for the opponent.
- A player whose cell phone rings shall lose the game, unless the position is win-excluded for the opponent.
Etc etc etc.
Second, a proposal. FIDE might want to adopt a rule similar to USCF’s 14E.
As it stands now, under FIDE rules a position like K+N vs K+B cannot immediately be declared a draw. There are helpmates, so the position is not a dead position.
So how about another definition:
- A player has minimal material to win who has at most K+N, or K+B, or K+N+N with no opposing pawns, and does not have a forced win.
Then the 14E-like rule could say:
- A player whose opponent has minimal material to win may claim a draw, even if the player’s time has expired.
- The arbiter may grant the claim, deny the claim, or postpone making a ruling.
The latter option might be appropriate in a situation where the opponent has a plausible, though not forced, win. By postponing a ruling, the arbiter is giving the opponent a reasonable chance to win through a blunder by the player, while also giving the player a reasonable chance to show that he is unlikely to blunder.
This topic has been touched on, by both Ken Ballou and me, in a couple of other threads in the Articles forum and the Running Tournaments forum.
