I don't believe you can change a programs playing "style" very much with only search changes. >>I think the same. Nice guy.

I was reading about Chess4.7 and earlier, the Greenblatt program etc. before I had even heard of the two of you. I had the Spracklens book which gave the Z80 code for Sargon 1 and was reading of their exploits and MYCHESS by Kittinger. You may have been active too at this time, I don't remember, but at the time they had the programs to beat. I should not forget the Cray/Blitz stuff, Hyatt was around before us too. But there are guys who will think the stuff I am remembering is recent history and will have much older memories. I think Bob Hyatt may be one of those. Then Psion came along and a bunch of Lang Mephisto machines and Rebel did well in 1986 in Germany. Of course there is no clear way to establish generations here, a lot of it I might be imagining and my dates and times might be wrong. I put myself as one of the new kids. I haven't written a great program yet but I am not in my prime. My first tournament was one YOU almost won and I almost finished last with a pascal chess program I hacked together. It ran on a 80186 machine. Yours ran on a machine that was overheating if I'm remembering the right thing. The really new kinds may think I'm an old timmer in chess. But is my history correct? In MY mind you sort of gradually faded in, I don't remember for sure where to place you or when you started. Can you fill me in? Your memories may very well be different. I propose a good estimate of "computer chess age" is the first organized computer chess tournament that our programs appeared in, probably an ACM tournament. If a commercial version was released before a tournament was attended we could count that too. Kaufman was involved years before in the opening book of a very early chess program, I don't know which one. So I do not know where to place him. If anyone can help me fill in this chart, it might be a lot of fun. I'm placing in the first few names that come to mind and sorry I haven't put in the really new guys but feel free to add names: Progrmmer name DATE First event attended with program ------------------ ------ ------------------------------------- Greenblatt Slate/Atkins Bob Hyatt ?? ??? Ed Schröder ? Early 80's? Spraklens ??? ??? Dave Kittinger ??? ??? Richard Lang ??? ???? Don Dailey 1986 WCCC Colgne Germany (Pre Rex) John Stanback Hans Berliner Hundreds of other, feel free to add and sorry I missed you!
