Strange mate
Hello all,

please have a look at this board:

game

I am playing black and am wondering why i can't take the white queen, since the white knight is pinned by my rook. Please elaborate since i am confused with my logics now

Because your King would then be moving into another check because the knight would now have the king in check on that square.

To understand this you have to forget about the word checkmate, and just understand that to win you have to be the first person to take the King. If you were to take the white Queen then the white Knight would take your King next move which would make the game instantly over despite the fact that it has discovered an attack on the white King by your Rook, your Rook could never take the King because without your King available, there is nobody in authority to give such an order.

derman53 summed it up the best...
You simply cannot move your king into Any square or capture a piece at ANY time that would place your king into any kind of check position.This also includes castling....If any of your opponents pieces are "checking" the empty squares between your king and rook,you cannot castle.You also cannot castle if any piece of your opponents,even a knight is between your king and rook.The only piece on the board that "cannot" check your king is your opponents king since they can never occupy a square next to one another.Finally,a king cannot be captured,there is no such thing in chess.Mate is only achieved when you or your opponents king is "checked" and then any proceeding square the king attempts to move to also places the king in check again or by attempting to capture your opponents piece would also place you in check again with another piece.Thats mate my friend.In your game,by taking the queen,you would be placing your king in check and that of course is against the rules....
