Originally posted by coquetteI am not so sure about that. See FIDE's Laws of Chess:
one other thing, and this is kind of weird, the position only has to "look" like it's the same position . ..
"9.2 The game is drawn ... when the same position, for at least the third time (not necessarily by a repetition of moves) is about to appear .... or has just appeared, and the player claiming the draw has the move.
Positions ... are considered the same, if the same player has the move, pieces of the same kind and colour occupy the same squares, and the possible moves of all the pieces of both players are the same. Positions are not the same if a pawn that could have been captured en passant can no longer in this manner be captured or if the right to castle has been changed temporarily or permanently.
Originally posted by Bull McCabeSorry,that post has been dealt with. Yes you can promote a pawn to a kings (queens) bishop and then switch the two kings(queens) bishops around, but you are still not switching the kings bishop with the queens bishop
After you promote pawn to bishop you have a pawn less on the board. so you can not repeat the position
Originally posted by coquetteOK, I get it. You're not trying to repeat a position that existed before the pawn promotion. You're saying that if you promote a pawn to a bishop that's on the same color as another of your bishops, you could THEN have 3 repeated positions, one of which has your two same color bishops switched. So you're not really swapping the KB with the QB; you're swapping 2 light-square bishops or 2 dark-square bishops.
the point is, for an example, that we are referring to a king or queen bishop, that will really be defined by the diagonals that it travels. thus, once a pawn is promoted to a bishop, then it may become a second bishop of the same color. now you would have a chance to "repeat the position" as far as it "appears that you have" . . .if only one does not disti ...[text shortened]... pieces as individuals, but rather as a "black square bishop" or a "white square bishop"
Trivial I admit, but interesting.
