I will add more puzzles soon.

5. Kd7/e7 is the same.

Very nice, though it stumped me.  Looking forward to more.

well if kd7/e7 it isn't a faster checkmate, and your always going for a faster checkmate!

sorry it is the same amount of moves

I have Changed the first Problem So that There is only one solution and added new ones.

Problem 2, there are many 6th moves that will allow white to mate in 2 so I would end the puzzle after move 5 when it is so obviously won.

Actually the Rook is the only Solution.

but, If you see any mistakes please let me know.

good puzzle..

Nice puzzles, very challenging!

I must disagree. Although there are many ways to win, the rook sac is the whole point of the puzzle. Without it, it's not so much instructive as it is repetitive, and it's no longer a "hard puzzle". And the point of a puzzle is for people to learn something, after all :)

 Actually, every single white move in the puzzle is the only move to win.

Earlier there was more solutions but I changed it so there is only one.

thanks a lot!

great puzzel
