The puzzle is wrong.  Checkmate forced in 5 moves starting with the knight fork. The key is Rf7. But if you like throwing away all your pieces at the end for a grand finale, then use the solution given by the puzzle.

Very good.

Ingenious, but there is no way to resist the fork on the first move unless you are completely sure of those tactics.

I would go for the knight fork. Good puzzle!

AaronSolt- look at the 2nd post 2nd solution. 4...d4 and it's a mate in 6.

I'm pretty sure they would only give a checkmate puzzle that has one solution with the least amount of moves. All they have to do is computer check it.

cool

Level 2400 puzzle at least...

In your line if 2...h5 then 3. Rf7 a1Q (or a1B) 4. Qxa1 Bb2, white no longer has 5. Rf8 checkmate due to 5...Kh7 so 2...h5 holds on an extra move for black.  Also if 2...h5 3. Rf8+ Kh7 4. Qe4+ Kh6, and there is no mate on the next move as opposed to 2...h6 3. Rf8+ Kh7 4. Qe4+ g6 5. Qe7 checkmate as pointed out by Goldname in post #156.

I thought that was very intersting the way the Knight was used to block the check.

My sentiments exactly IncrediBill!  I never got beyond that knight fork as the first move.

very nice

i'd have gone for the knight fork. just too tempting

Interesting puzzle, however, the position offers no motivation to win in 5 moves. White could just as easily win in a hundred other ways.

hmmmp.....

 Great alternatives especially having the pawn waiting to upgrade. Chess.com should put alternates in the solutions. Thanxs 4 the input.

Insane, the black rook should have taken the queen.

Best 5 move checkmate ive seen xD

i dont agree to move the queen to c4 after knight fork because now the black rook can move to e8 and move the h pawn to h6 and king to h7 that will buy him extra moves.

i hate this kind of puzzle. because you are going to win like no mater what.
