A very deep combimation, that Tasc R30 or Genius 2 running on a pentium would
take between a few months and a few years to find.
The best Novag computer, the Diablo 68000, finds 26.Nxh6 after 7 months
and a half (Pierre Nolot has let it run on the position for 14 months and one
day, until a power failure stopped an analysis of over 80 000 000 000 nodes!)
but for wrong reasons : it evaluates white's position as inferior and
thinks this move would enable it to draw.

Comments by Feng-Hsiung Hsu (Deep Blue Inventor)
Kasparov played Nh6 here. DT-2 agreed with Kasparov's analysis after
going down the line given in Informant, but could not find the move
on its own in one hour time. When letting it run overnight, it produced
Nh6 after 8 hours (but would play it with a 6 hours/move time control; that
is, it got first indication that the combination might work after about 6
hours), with the variation 1. Nh6! c3 2. Nf5 cb2 3. Qg4 ... which wins for
white.
The first position, by the way, was from the Kasparov-Karpov match in New York.
In fact, we were in the press room during the very game. None of the
grandmasters on site got it during the game. Well, they saw the move, but did
not think that it works.
