its 50 moves without a capture or a pawn move. a "move" is counted when both players have moved so it's 50 moves each.
50 move rule
Sort:
It becomes really important in endgames like Queen vs Rook, Queen vs Knight, and the Bishop and Knight checkmate where you know there's a win but unless you've studied them you may not be able to find it quickly enough.
50 moves each without a capture or a pawn advancement. This is how moves are always referred to in chess. A game had only eight moves if white gets mated on black's eighth move.
has this eer happened in GM games?
Certainly, but less often. Below the master level, Q vs R draws 30% of the time. At the master level, Q vs R draws 20% of the time.
Most often, in a GM game, if they can't find a mate in 50 moves, they realize it's not going to happen and agree to a draw before then. But even they play it out sometimes, if one of them thinks there might be an advantage to doing so.

Is that really so? That is an amazingly high percentage.
Yeah, per my 3.5 million game database for rating > 2100 and for rating >2400. Susan Polgar is an expert at the rook's defense and she's proven many GMs cannot beat her. But Q vs N is simple and completely won at the master level.

There are a few "exception" positions in Queen Vs Rook where the Rook does have a forced draw but one would think this should happen less then 20% of the time...

I think "think" the 50 move rule was changed briefly, and then changed back again..I'm not sure maybe there are exceptions? Anyone have a copy of the offical rule book?

The fifty move rule can draw endgames which would objectively be losing for one player.
this rule means 50 moves per player without a capture; correct? or is it a total of 50 (25 each)? thanks
