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."

here;s the position
[d]r3qb1k/1b4p1/p2pr2p/3n4/Pnp1N1N1/6RP/1B3PP1/1B1QR1K1 w - - bm Nxh6;

enter the position in your favorite engine -- and play the winning line above ..

it's incorrect - Nxd6 loses to the simple Rxe1 ...so no chess program will find
the winning line above ..actual game went as follows with 27.Nf5 ..I like
Kasparov move better ;>)
