Re: Fide Should create a New Computer odds vs GM Championship

That seems to be a good idea indeed to create another discipline of chess to determine each year a human who is the best at employing anti-computer strategy.

Re: "Intrinsic Chess Ratings" by Regan, Haworth --

Since our graphs represent absolutely different things, it's perhaps nothing but a coincidence. :) I agree with you that 100-150 points inflation per 4 decades is an exaggeration. There are people who hold that chess skills have not much improved in the course of time. And they see that Karpov was r...

Re: Most common destination squares from 1M chess games

Very interesting. It also would be interesting to see average centipawn deviations from the engine's best choices for each square. In other words, which destination squares tend to be associated with more accurate play.

Re: chess statistics scientific article

I've already posted it here, and, no, it was never intended to be published anywhere. The methodology of such analyses is still raw and a lot of improvement is needed.

Re: Next Komodo vs. GM handicap match - "Standard chess

I've been wondering about one thing - why did Erenburg play e4 only? Was he secially instructed to do so, or was he really optimistic about his abilities to keep up with K10 in open positions?

Re: "random mover" chess programs

CCRL 40/4 has a random move maker BrutusRND. It is placed last, as you could expect, but, surprisingly, it has a positive rating - 210. http://www.computerchess.org.uk/ccrl/404/rating_list_all.html I have played several games against it trying to deliberately lose to it. Mostly it has managed to av...

Re: Three humans have a 60%+ match with Stocikfish

I have data indicating that humans rated 1600-1700 have barely above 40%, whereas Houdini 1.5a and correspondence games from the ICCF W28 have around 75% coincidence with Komodo 8.

You've got to have a big strength difference and similar-type positions to get meaningful conclusions.

Re: Next Komodo vs. GM handicap match - "Standard chess

In addition to calculations below, one also must take into account the role of anti-computer strategy. How succesful a human is at employing anti-computer strategy depends on the depth of engine's search. In earlier times computers were sepecially vulnerable, because they had both slow hardware tha...
