Consider the 'parity' of knight moves.

You sound like you have had more beers than I have.
Perhaps we should start posting in General.

Oh, I get it now. It's one of those ones where the two players don't actually play chess, they play a puzzle.

There's a rook missing, so it must have been captured by the dreaded Black Knight. A possible "game" could have gone:

1. Nf3 Nf6
2. Ng1? Ne4
3. Nf3 Ng3
4. Ng1? Nxh1!
5. Nf3 Ng3
6. Ng1(WTF?) Ne4!
7. Nf3 Nf6?
8. Ng1? Ng8?

Oops, you said it's black's turn. So I guess it's a job for black's Queen knight.

Black must have played ...Ng3xRh1, though it does not matter which Knight takes the Rook.

If black is to play, then knight moves alone cannot have done the job. The only solution for an odd number of moves for white is if black took the rook on g1 with a knight?
