Originally posted by stevetoddI don't know if there are any rules about moving pieces of your colour which your opponent kindly has put on the board for you... But I doubt it's legal to promote your pawn to your opponent's queen. I wonder if one could construct a position in which this would actually be desirable.
although that made me laugh. it wouldn't be a legal move would it?
Originally posted by yashsryour opponent is unlikely to resign when he cannot lose, and you cannot win on the clock (otb) when you do not have mating material, in that instance it's a draw
the opponent may resign as someone mentioned or you may also timeout the opponent, there is a better chance of a timeout win than over a win by resignation..

about resigning I am not sure...well anyway who would resign in that kind of position

Originally posted by BigDoggProblemyes but I think the lead up to this position means that the opponent helped/blundered badly, what he meant was that mate can't be forced
You can if your opponent has certain pieces on the board. For example, [fen]8/8/8/8/8/1K6/2N5/kn6[/fen].

Someone listed most of the rules but forgot en Passant. See the help section of this site for the best description available. Basically if you move a pawn 2 spaces and it pulls even with an enemy pawn, the next turn (and only the next turn) the enemy pawn may capture it diagonally (leaving the square where the pawn moved to empty). so if I have a pawn on b5, and my opponent plays a7 - a5, I may capture b5 x a6.
Speaking of strange queening situations, in the US an upside down rook is understood to be a queen. However a GM was playing (in europe?) moved a pawn to the 8th, and since he had a queen, he grabbed a rook and placed it upside down. Since this was not their custom, his opponent complained to a TD who ruled that by touch move, the GM had to promote the pawn to a rook. (Does anyone remember who/when/where this was?)
