I've always thought of Deep Junior as some sort of ultra-tactical engine much like rybka-winfinder. In the run-up to the Deep Junior-Deep Fritz match I was looking up Deep Junior on the net and saw this page Its funny how Kasparov declares every program he plays the "best program".
On the other hand I pity those who buy programs because of the hype generated by a championship win such as Shredder/Junior/Zap and finding it doesn't perform that way on your home pc. That 8 processor/8 GM RAM machine that Junior used to play Kasparov is not what the average chess player has at home. (Well the average playchess engineroom freak will beg to differ but those are a hundred or so).
