Isn't that the same than:
Code: Select all
Rybka GM
Lose 0 0
Draw 0 2
Win 0 2
?
In the end what matters is point difference.

No, I guess my table isn't clear to you. Perhaps this equivalent table is better:
Code: Select all
Rybka GM
Rybka Loss 0 4
Rybka Draw 1 3
Rybka Win 2 0
If you prefer, this is the same as:
Code: Select all
Rybka GM
Rybka Loss 0 4
Rybka Draw 0 2
Rybka Win 2 0

If the human never wins this is equivalent to draw odds, yet there is still an incentive to try for the win.
If Rybka gets a draw, human deserves 3 points? But if Rybka wins, only 2 points will be rewarded? Don't you think that's slightly unfair.
I would slightly modify your version and propose this scoring instead which would make sense mathematically:
Code: Select all
Rybka GM
Lose 0 0
Draw 1 2
Win 2 4
A handicap match can't really be fair. I was trying to give at least draw odds, while yours is probably a bit less (depending on what the GM's chance of a win is). For a strong enough player yours might be better.
