It’s Your Move: daily chess puzzle #337

White played 1 Nf7: evaluate; and also consider alternatives

Schneider v Dieks, Manila 1974

Solution

Easy part first: 1 Rf7+ is a simple win.

1 Nf7? is a blunder: 1…Qe7! 2 Qe7[] Re8

3 Qh4+ Kg7 4 f3 unclear. In the game, White played 4 Nd6??: my Megabase says 1-0, so it might be zeitnot, since 4..Rg1+! mates next move with 5…Re1 mate.
