Lectures, thesis, ICCA journals, everything. While I'm not Bob, I will take a stab at answering your questions. DB and later DBII were massive machines. DBII had 400+ CPUs designed for the sole purpose of examining a chess board. While I believe that the software was not as advanced as todays, I do have to remind you they did some pretty fancy extensions (among other things) that cannot be afforded on a PC at this time. Did DB or DBII ever make a move that cannot be reproduced by a computer now? Not that I have found. If you give a certain engine a certain amount of time, most will always find DB moves. Some faster, and some slower. Some a lot faster, and some a lot slower. Why? Anyone can look at the games played against DBII and tell Kasparov was *not* on top of his game. DBII was never given the oppurtunity to shine, thus, it never did. There are I believe 2-3 positions in DB/DBII's history that still give some programs a hard time, but nothing that switching PCs or programs won't solve. However. You can look back at Deep Thought and Deep Thought II and pick some of it's games to compare. Granted, you will not have a one on one comparison, but you will have a close one. DBII was fairly stronger than DTII, however, they are in somewhat the same realm. Nolot. Back in the 90's when Nolot released his position suite, he said that it would be 10+ years before computers where getting these moves (and lines) right. DTII completly squashed Nolot. At that time, no program or PC could even *dream* of getting those positions solved. At present day, *some* programs with good HW can get *some* of the Nolot positions correct. AFAIK none do as well overall as DTII. And please, try to keep in mind DTII was 2 generations before DBII. 2M nps vs 200M nps. (Ok, 150M nps. Whatever number you want to pick.) TPR. DTII was crushing GMs at a time where if you had brought a PC to play a GM, people would laugh at you. After the Kramnik-DF7 match, it's looking like you'll get this same attitude nowadays. I will leave you with this; why if we have advanced SO much in computer chess, is the "best" computer chess software on the best computer hardware getting torn apart by a GM? Because he got the software in advanced? Give me a break. That's part of normal chess. You study your opponenets before you play them. You don't think Frans and his crew were going over ever Kramnik game played? I am sure it helped Kramnik, but nothing like most people think. Look at the DT games. Look at the DF games. It is clear to me that there is a pretty huge difference in quality of play. ** All of you anti-DB guys can go ahead and reply all you want. I've heard your side 1,000 times. I don't agree. So go ahead, waste the keystrokes. It's your time, not mine. **
