Nolot's analysis as reported by Baudot:

Weinstein - Elyoseph, Israel 1992

This one is really beautiful and should resist computers for quite a long time, maybe until next century? 1.Ng5!! hxg5 2.hxg5! Rac8 3.Nf6!! Nb8 (black can also try 3...gxf6, which loses if white play precisely : 4.gxf6 4...Rfe8 (best defense) 5.Qh5 Kg8 6.Rxc5! Bg6! 7.Qh4 Bxc5 8.Be4 Ne7 9Kg2 Qd5 10.Bxd5+-) 4.Qh5 Bxf6 5.gxf6 gxf6 6.Rxc5 Rxc5 7.Be4 f5 8.Kg2 Rg8 9.Rh1 9...Rg7 10.Bh6 Nd7 11.Bxg7+ Kxg7 12.Qxh7+ 1-0

In fact, Pierre is not sure this one is 100% correct. Any improvements are wellcome!

Comments by Feng-Hsiung Hsu:

After 9 minutes, it played 1. Nf6, expecting 1. ... Rfc8 2. Nh7 Kh7 3. Ra1 ... The score was slightly nagative for white. On longer searches, it went up to half a pawn and creeping up.

Later comment by Feng-Hsiung Hsu:

It is not clear to us either whether 1. Ng5!? actually works.

My own experience:

I ran this one on a quad 450 mhz Xeon.  After 15 minutes it wants to play Nxh6 with a slightly positive score.  After 300 hours (!) it still has Nxh6 and the score is +1.

Nxh6 is not the key.  My program never wants to play the key (Ng5).
