"Neue Zürcher Zeitung" 2009 mate in two

In my way of conceiving the best qualities of a composition, it is perhaps lesser pleasant in some aspects to the former original presentation (the Bishop in g8 perfoms just a virtual rôle, and the Queen is downgraded to a single jump over g3 in a set mate) white Pawns are admitted (while a contruction without them is a plus)

In the other hand, it stress over "thematical purity" : the black Pawn in f7 instead of a Knight demontrates the thematical idea more clearly, the importance of the f5 square is improved, and in the real play the (b) defense is not a random Knight move as before, but now just the Pawn 'hesitation' to f6 before the paradoxical f7-f5 . other qualities (mainly the effects of the black Rook batteries and
the changed mate in try 1. Ng6 c4 are preservated.

Well, it seems that the archives are no longer available for free. The original, just for the record, has wQ b8 >> c7 ; wB g8 >> d1; wP f3 & wPg3 out; a wB in g3; bR b4 >> a4; bP b3 >> d2; bP f7 & bP h2 out; a bN in b8 and another bN in f7

Solution of the present Version:

Set: 1...fxg3 2.Qxg3 #

Try: 1.Nf5 A (threat 2.Nf2), but 1...c4! a

Try: 1.Ng6 B (threat 2.Rh4) ; (if 1...c4 (a), then 2.Nxf4 #) ; but 1... f5! b

Key: 1.Rh4! (threat N~)

Variations: 1...c4 (a)/ 2.Nf5 (A)

1...f5 (b)/ 2.Ng6 (B)

1...fxg3 2.Qxg3


This one evolved from a scheme quite similar to a 2-er by N. MacLeod (in fact I had an unpublished - and certainly not fit for publication - rendering with 4 tries, of that scheme, before knowing of Mr.MacLeod's composition)
