Subject: Does any program get this?

Author: Francis Monkman

Date: 17:15:54 05/01/99

During a game with Genius4 in 95, the following position arose
after 17 moves by each side:

White: Pa2,b2,c4,e5,f4,g2,h2 Ng3,g5 Bc1 Ra1,f1 Qe2 Kh1
Black: Pa7,b7,c6,e6,f7,g7,h6 Na6,b6 (!) Bc5 Ra8,f8 Qe7 Kg8

White was pleased to find the continuation:

18 f5! hxg5
19 f6 gxf6
20 Ne4 Rfd8
21 Nxf6+ Qxf6
22 Rxf6 Nd7
23 Bxg5 Nxf6
24 Bxf6 Kf8
25 Qh5 Ke8
26 Rf1 resigns

It would seem obvious that White is winning within a 9-ply search,
so why doesn't any program find it? (You're of course welcome to
see for yourself of it's 'legal', but I can't find any get-out for Black.)
