Fortunately, the pioneers of computer chess were quite bright and figured out most of the techniques we still use today. (I'm referring specifically to the authors of programs at or before Northwestern's CHESS 4.0) Lots of small improvements have since been added by the stronger programs, but you (as an end user) may not notice these in an entire tournament! The only engine improvement you would always notice is null move, and better handling of passed pawns and pawn structures. As a user, it's easy to chalk up these improvement to deeper search from better hardware, even if it is actually an improvement in both the software and the hardware. There are further advancements that will be coming out in computer chess in the near future which were impossible until today's strong hardware became reality. When these new features become implemented, they will allow tomorrow's programs to far surpass anything we have today. Dave
