Can you show me one main line of deeper blue that the best chess programs need many hours to get? My analysis suggest that deeper blue is 2-3 times faster than Deep Fritz pIII800 in finding some main lines. I am sure that if we analyze every position that Deeper blue pondered for some hours on fast PC we can find more positions when top programs find main lines that begin in the same moves as the main line of deeper blue. The interesting question is what is the speed ratio in these cases If the speed ratio is the same as the speed ratio that I found then it means that deeper blue is not strong. If in most of the cases when top programs find similiar main lines the speed ratio is at least 100 then it means that deeper blue was probably stronger then my impression. Unfortunately I found only one volunteer to help me to analyze the positions that deeper blue pondered and I am not going to use more than 20 hours of computer time per week to analyze. Uri
