Deep Blue searched 11 to 13 ply
so using your own logics it loses with induction then!
note that a 8 processor 700Mhz Xeon is going to be quite slower
as the follow up of the P4 probably (where they fix the probs it has
then it can do 4 instructions a clock which is 25% faster as 3 instructions
a clock possibly can deliver) one day is called a PIV running at 2 Ghz
and in a dual flavour.
700x8 = 5.6Ghz
2.5Ghz x 2 = 4Ghz (but dual better speedup as 8 processors and 4 instructions
a clock wins always from 3 instructions a clock).

Vincent
