I do, and I have. I have a lot of programs and there isn't one I haven't beat in
a slower time-control. Anti-computer chess is alive and well though using it
wasn't even always necessary. This would NEVER work against a GM, and against a
2700 player I would have quite simply NO chance. EVER. And as you say, chess is
chess, so using anti-computer chess is by all means an acceptable solution. You
want a deadly opening with White? Try the Ruy Lopez Exchange variation. In the
hands of an expert, computers program are in very big trouble. That's just an
example.

Yes.

Highly debatable. The reason DB didn't convince GMs of being superior, is
because it was inferior in most games. For whatever reasons Kasparov was not
able to convert these positions, but the inferior positions were due to inferior
positional play.

Aspects? Positional play, strategic play, endgame play. Mind you, I think Tiger
plays great, but that is what differentiates it from a GM.
