Re: White to move.
Actually Critter first wanted to play 1. Nh6+ which I think is also winning, if slower. After (forced) 1.- Kf8
Analysis by Critter 1.4 64-bit:
2.Bf6 (AGAIN) gxf6 3.Nf5 Kg8 4.Qh6 Nac5 5.Qxf6 Ne4 6.Nh6+ Kf8 7.Rxe4 dxe4 8.Nf5 Kg8 9.Bf1 Qd2 10.Rd1 Qg5 11.Nh6+ Qxh6 12.Qxh6 Bb7 13.Bh3 e3 14.fxe3 Be4 15.Qf6 Bg6 16.Bf5 Bxf5 17.Qxf5 Rad8 18.Rf1 Rd7 19.Rf2 Rc8 20.Kg2 h6 21.h4 Kg7
+- (2.40 ++) Depth: 23/77 00:20:03 3686mN

Re: White to move.
OK, close and 1.Nh6 does appear to be winning, too, but white does have better in 1.Bf6. While both Critter 1.4 and Houdini settle on 1.Bh6 as the move to play, the follow up is where they seem to be going somewhat astray.
Bear in mind that I am not so good at chess to be pronouncing play by either the programs or the individuals involved good or bad. I am taking this from a column by GM Lubomir Kavalek in 2007. For me, and this means absolutely nothing, it is the follow up moves that determine the validity of a a player's idea. Now, after 1.Bf6 gxf6 (1...g6 2.Qh6! Bb7 (or Nac5) Rbd1! white threatens to lift one of his rooks to the fourth rank. (Kavalek)
What about now from this diagram for white's next move: Does either Houdini or Critter change it's "mind" as to best move for white? (And btw, thank you for your response. My chess computer is in shop right now. Fritz 12 kind of gets stuck on 1.Qh4...)

Re: White to move.
Apparently this position prompted the following from you in 2007:
That is impressive! I felt no program could solve this in a reasonable amout of time.
It took nearly 12 minutes to see it was winning outright, nonetheless a very impressive result indeed!

Hardware and software have improved a fair bit since then.
