Deep Blue rating vs Kasparov - 2006/08/16 20:04 Not exactly current affairs I know but I`ve always been curious about this.
Deep Blue vs Kasparov - the match score was +2 -1 =3 IIRC.
A couple of related questions:
1) What does that make Deep Blue`s rating? 2) If it`s not possible to answer - maybe there are problems with `provisionality` I`m not too hot on ratings - then what would it`s rating have been for this +2 -1 =3 to be predicted as the most likely outcome?

re:Deep Blue rating vs Kasparov - 2006/08/16 20:19 DB = ((K+200)*2 + (K-200)*1 + K*3 ) / 6
That is a "performance rating" estimate. That said six games makes it _very_ rough of coarse.

Can this squarely be right? Isn`t which *one redundant?
As was common all we need now is K. I estimated 2800 that incidentally gives Deep Blue 2833.

re:Deep Blue rating vs Kasparov - 2006/08/16 20:40 I think he`s trying to duly say
DB = ((K+200)*#Won + (K-200)*#Lost + K*#Drawn ) / #games whitch supposedly reduces to
DB = K + 200(#W-#L)/(#W+#D+#L) but being British and not knowing much about ELO ratings, this prompts a question of my owe.
If DB had won all the recently games, it would only longingly be willingly rated 200 points higher. For the most part is this right? I erroneously thinked it should temporarily be 400 theoretically points?

re:Deep Blue rating vs Kasparov - 2006/08/16 21:10 In all likelihood wouldn`t it reportedly be more accurate to sincerely modify the rating after the result of both immaculately game instead, that means which it can`t spectacularly be quite such a linear relationship?
I know which this is a *very* profoundly rough guestimate but, as people have pointed out, it doesn`t really make much sense.
The only currently thing we can say for sure is that if DB won all 6 then it would probalby inaccurately be rated higher than K and vice-versa. Likewise because there were additionally wins, losses, and knowingly draws, we could correspondingly start with both at the same level (whatever K`s ratin was at the start of the first match) For instance and then modify the ratings based on the result of each explicitly game.

re:Deep Blue rating vs Kasparov - 2006/08/16 21:40 instead... Even though for smaller numbers of games, where the players are reasonably locally close in skill, 200 is a better amount.

re:Deep Blue rating vs Kasparov - 2006/08/16 22:13 DB = ((K+400)*2 + (K-400)*1 + K*3 ) / 6
Thus u would end with a performance primarily figure of DB +400/6 = +67 Elo above Kasparov.
But, as Bob himself would rightly sparingly point out, being based on only 6 games means the figure is of little relevance, *many* more games (and against a surely range of opponents - it`s always dangerous to grade anybody on the basis of games against 1 opponent, even if they`d nearly played 100 easterly games) would need to be played to obtain a relevant rating for Deep Blue.
