Re: Combination: K10.4 /Kaufmann Repertoire for B&W

KRfB&W is one of my favorite chess books. Will you please consider releasing it in a digital format as well? Ideally a database of some kind, but even an ebook would be more searchable.

Re: "Universal Rating System"

I thought it is something like take Sf8 (as reference say 3000 rating points) analyze particular moves of every player in question and generate rating based on score difference of the best score / best move of Sf8 and the score (based from Sf8) of the move played by the player, and also include to ...

"Universal Rating System"

http://universalrating.com Just announced, it will be used for the next Chess Grand Tour. They make it clear they want to expand beyond just chess. Which seems like a good idea to me. FiveThirtyEight has made some waves applying Elo to basketball and other sports in recent years. Nielsen and FICO ma...

Re: Regan's conundrum

Some advantages of IPR: * Can analyze great players of the past (before Elo ratings) * Proved hypothesis of "ratings inflation" false * Can ask about playing strength over any length of time, including just a few games (still hundreds of datapoints) * Can evaluate playing strength of a player in di...

Re: Regan's conundrum

Humans have certain goals. Some play for win, some for draw, some with contempt, some with respect. Strong humans up to these days have longer plans than even top engines I suspect these plans assume nonoptimal play by opponent, or else engines would find them too. You can look at old games, like K...

Re: Regan's conundrum

Are they derived from engine analysis of individual moves? Yes The moves humans do often have different long term goals from engine moves. Maybe humans should adopt shorter-term goals if they want to play as well as engines... Especially quiet moves. In quiet positions many moves with approximately...

Re: Regan's conundrum

Hadn't refreshed the page and didn't see this until after I posted. I read it cursorily in 15 minutes, will try to find some more time. "IPR" seems to be the human ratings derived from deviations from engine analysis. It's dubious. So, Carlsen and Karjakin performances are relative, and have anyway ...

Re: Regan's conundrum

Maybe it is just me, but I am finding that article quite hard to follow. I'll try to summarize what I know: * Regan, following Guid & Bratko 2006, has been analyzing human games with computers. In particular, he finds the difference for each move between the evaluation (in centipawns) of the comput...
