This is an important observation that you make. I can think of no other
person having to attain that recognition of GM strength
by playing a series of games in this manner that Rebel is now doing. It's
not the natural way of proving that one is of GM playing strength. GM's
typically acheive their status through tournaments by playing a variety of
players, both GM and non GM. Not in this long arduous way of playing well
prepared opponents once a month. The cards are somewhat stacked against the
computer opponent as computers do not possess that ability to prepare
against an opponent as effectively as a GM. It just is not a strong component
of computer play to prepare and adjust depending on who the opposition is.
I would caution against using this format as a comparison to how humans
gain that ultimate recognition of, "that person truly plays like a GM".
Now in the end if Rebel manages to attain a GM performance of say 2550,
that could tell us that there is a possibility that given ordinary playing
patterns (ie: tournaments) that the 2550 could translate into something higher.
Somehow the pendulum has swung. In the past we often pointed out unfavourable
conditions for humans as in playing in noisy conditions, or that they received
no monetary incentive to play their best. Now we are in a sense asking a player
to play someone who has a month or so notice while it in a sense has no notice
at all( for a computer, "knowing" ones opponent is marginally helpful and
that only when the programmer attempts to include information on the opponent,
but I can't imagine that as being much of a factor). This is not to make excuses
for Rebel's two losses (If one counts Anand's win as well as Rhode's - toss the
Hoffman game out unless your into counting ones and zeros), but simply to
draw a comparison to the actual way humans have to acheive GM strength and
recognition.
