Sjeng played d5, the same move was played by Ponomariov earlier
this year in Linares against Adams. Alex Kure criticised it as being
premature (citing Adams). Sjeng got into a worse position and Brutus
slowly worked its way through a win.

How long does your favorite program need to avoid it?

Brutus played Qh5 and went on to win after the double piece
sacritice. I had a discussion with Tony Werten, who claimed
you had to search really really deep to see the compensation.
I think you just need good kingsafety :)

How long to get Qh5, a winning score and see the double piece sac
(Nxg6 Bxg6) and KEEP it?

Junior-Sjeng. Again Adams and Ponomariov in Linares 2002! Black
must not accept the rook sacrifice. How long to avoid it?

[D]r4rk1/5p1p/p1pb1n2/1p3bp1/3PR3/1BP2PPq/PP1NQ2P/R1B3K1 b - - 0 18

Sjeng played Qxg7 and Junior answered from book. I think I can
omit the rest of the story.

How long to avoid Qxg7?

GM Alterman - Sjeng Anti-Human

Black plays Nxc3!!

Anyone else find this?
