I knew there had to be an explanation as it isn't too deep of a move like Qe3 in
the DB-Kasparov game.

I made my way to 1985 games and i was wondering what you could tell me of the
search depths for both CB and Hitech during their matchup i am about to start
analyzing this game as i had already found a win for Bebe in it's game against
Hitech. I had heard that Hitech's nps was 200K in 1995 but what about before
then?   thanks again
