Bruce does not use SE in the way that DB used it.
I do not know about one programmer who use SE with the same algorithm of deeper
blue.

I need to explain how is it possible that deeper blue could not see one
impressive move that top programs need a long time to find inspite of it's
hardware advantage and if singular extensions that were used were
counterproductive in games
then it may explain the facts that I see.

I guess that giving programs hours to analyze Kasparov-deeper blue games can
help programs to see some good moves that deeper blue simply missed in the games

I already found that they can see Kh1 that is winning in game 2 and they even
need only few minutes to see it and I expect them to find more moves if I
continue the experiment.

I analyzed for hours only few positions from the match and I hope that if other
people help me then we can find some tactics that deeper blue simply missed to
get a more convincing evidence(Kh1 is not tactics and the difference is only
positional difference from programs point of view).

I believe that a lot of tactical things that programs can see in games and not
in test suites are not based on singular extensions.
