Mate in 2

Huh?

White is threating mate in 1 with the queen moving to the first rank. In order to prevent this, they have to either capture the rook or move the knight to cover that square and prevent the queen from moving there. If the knight moves, the queen captures it and checkmates. As the problem shows, if the bishop captures the rook, then the bishop captures the queen.

1. Nxd1 [2. Qf2#] Qe2 2. Rg1#

I prefer Sam Loyd's original version without the pawn on f4 and then mirrored

yep Nxd1 h6 then boom Qf2# or any of the multitude of mates that come from it, it makes no odds, but your way is just odd

Easy as that. Just an alternative. Of course, after 1. ...Kg1 2. Qg3+ there is ...Bg2, but that just ends in Qxg2# anyways.

black was dumb to move its king there

Sure he was...

Anyway the puzzle is annoying because there's about a dozen different mates in 2.

höh?

the solution is wrong because black can capture the rook with his king=> no mate in 2

jamessauls  solution is wrong as well because he ignores the black queen which can interfere

drayrs solution is wrong because its not mate in 2 when the king moves to e1.

the right solution is rook to g1 gollowed by queen to e1.

facepalm

yiks right...

should have used more time on checking that.
