if kc7, then Na6+ and after the king moves, it goes back to where it started and is mate in 61. they key is to avoid checks

 Oh, can we smell the irony?


 

This is a very good puzzle because of these reasons: on the board the only things that can move for black are the pawns, the rook, and the knights, if any knights move, then white can check mate by moving  f6 knight to check the black king.

White has to come close to the rook in order to force black to move a pawn until there is nothing left to move except one of the two knights, and when those move the f6 knight can deliver check mate. If black loses the rook he can no longer waste moves and needs to push the pawns or move the knights, since he cannot move the knight it would have to push the pawns and once he cannot push them anymore he would have to move a knight and get checkmated.

White has to lose a turn every time black makes a pawn move (in order to get back to the rook and force him to move another pawn) and the only way is to get away from the black knights because they could move out and check him which would bring black back in the game.

This is an honest puzzle, analyze the moves and figure out why White made them, then come back and do it again.

Isn't this a draw? White has made over 50 moves without capturing or moving a pawn. Unless I'm mistaken, if either side goes 50 moves without capturing or moving a pawn, it is a draw. (This is probably incorrect due to the validity of the puzzle, and the 50 move draw rule is if both sides go 50 moves without moving a pawn or capturing.)

 Can somebody explain the 50 move draw rule?



P.S. Great demonstration of triangulation!

It's zugzwang. Wherever black moves, he get's checkmated!

It is not a draw because black has made pawn moves. The 50 moves draw doesn't require a pawn move or capture from each side, only from either side.

 No because each time the king and rook were in identical square as before, a pawn had been moved thus creation a new position.
