Dr. House seems to need a team to help him with diagnoses. Similarly, could a team of chess grandmasters stand a better chance of beating Deep Blue or Fritz?
Kasparov: “Karpov, investigate B-B4; Fischer, consider the Queen sacrifice!”
Karpov: “B-B4 leads to disaster!”
Fischer: “Queen sacrifice looks good.”
Kasparov: “Okay, Karpov investigates the enemy Rook responses; Fischer, what happens if they try to move the pawn?”
Prize matches against computers are played under a time limit. Under a time limit, I can’t imagine that more people would be helfpul; the distraction and waste of time involved in explaining your thinking to another person would overwhelm the small advantage of having an extra mind.
Given unlimited time, I imagine that two really good heads would be better than one.
Every top-flight grandmaster runs with an entourage to help him. They help research the opponent, innovate lines, and analyze adjourned games. Does that help?
But having Bobby Fischer on your team wouldn’t help:
Kasparov: “Fischer, consider the Queen sacrifice!”
Fischer: “The Queen is Jewish! Sacrifice her! And where are my shoes? You’ve stolen my shoes! The knight is plotting against me.”
I think it’d work if there was one main guy, and he rules as dictator over his grandmastermensch. He can assign them roles of playing out certain possibilities, and he can use them as error detectors. He can always overrule or ignore at will, especially if time matters.
