....and mate in two against any defence.
Came across some very old chess literature which contained these classic mate in two puzzles.

1...Bxe4 2.f4#
1...Rxe4 2.Rxa5#
1...Kxe4 2.Re3#
1...Rd4 2.Qe7#
Spiffy interference motif.

Same again - white to move and mate in two:

Unfortunately for Black, all of his checks cut off Ba8's attack on Rh1, allowing the Rh1/Bg1 battery to fire.
1...Rb7+ 2.Bb6#
1...d5+ 2.Bc5#
1...Re4+ 2.Bd4#
And finally
1...e1N/Q/R/B 2.Rf3#
1...Ke1 2.Qa1#
Tries: 1.Rd1+? exd1N! and 1.Qxa8? e1N!

The perfect zugzwang position ?
skeeter
When black is on the move, 20 possibilities each leading to checkmate in 1.
When white is on the move, Nd4! creates another zugzwang position with checkmate in 1 after all black's moves.

NO, but 1.Nd4 Qxd4 2.Qxh7#does
I meant that after 1.Nd4 White threatens 2.Rg4#(not Rf5,sorry).
Zugzwang means, it's a problem that it's your turn, but since white threatens mate (Rg4🙄, after 1.Nd4 white wins regardless whose turn it is. Therefore, if it's white to move (as the thread title indicates) there is no zugzwang.

Originally posted by jfkjmhI agree that this problem isn't about zugzwang. After 1.Nd4, a move like 1...Ba1 does not change anything. If it were a true zugzwang, all of Black's moves would damage his position in some way.
