Re: A poor man's testing environment

In fact many times Larry has noticed that chess programs (and Komodo specifically) might score some opening much higher or lower than theory suggests and we will spend a significant amount of time trying to understand why and determining what corrections to make - which sometimes involve inventing ...

Re: Testposition 60 - Bishop vs Knight

Thanks for your contribution and analyse Lyudmil! Right now I have limited time but will be back with this position in a couple of days. Regarding 1-a5 - i was under the impression that white worsen his position by playing an early b4 - have a look at the previous analyse - black won all those vari...

Re: Ending

Hi Don. I do not understand how search functions, but I would not accept for granted the assertion that evaluation is absolutely unimportant. When you should search more than 30 plies to see the logical development of a game, you should be aided by some practical knowledge. One of my favourite examp...

Re: Ending

Hi, Sune. Thanks for posting interesting positions. That is why chess (much more human chess at that) is not only about what really there is in a position, but about competition too, competition of nerves, personalities, idyosyncracies, etc., something that not always favours the objectively stronge...

Re: Who Do You Feel Is The Greatest Human Chess Player?

I think the question is meant to signify the greatest player in terms of overall quality of chess. In this respect I would definitely pick up Fischer. Fischer annihilated all of his opponents in the 1971-72 streak and would have done so with Spassky, the then world champion, if it had not been for a...

Re: Ending

[d]8/8/3p1k2/2pP2n1/2P2K2/3B4/8/8 w - - 0 0 It is interesting to know how could black improve on 1.Bf5 Nf7 2. Bd3 Ne5 3. Bf1 Kg6 4. Be2 with a draw. Otherwise, blocked pawns would favour the knight, pawns on squares the colour of the bishop would also play into the hands (hooves) of the knight, but...

Re: Testposition 60 - Bishop vs Knight

This is merely a discussion (and a celebrated game!) of B vs Kn in an ending with pawns on both flanks. Such an ending is very difficult to hold for white [D]6k1/p2b1ppp/8/8/3N4/1P5P/5PP1/6K1 b - - 0 1 [pgn][Event "Bishop Superiority"] [Site "The Hague"] [Date "1928.??.??"] [Round "?"] [White "Stol...

Some spare stuff for the Little Compendium

Hi all. Actually I am not working on it any more, but I had some spare stuff and decided to release it. New things in the latest addendum (alias spare stuff): - closure of files/sides - scaling of evaluation factors in respect of long-termness - correlation parameters - a bit more on attacking (atta...

Post-final release of the Little Compendium

Hi. Here is a post-final release of the Little Compendium (a small addendum and the full version). God bless the inventors of prefixes. It is already the second time that I think a version would be final, and every time I am proven wrong. With such kind of assessment it is difficult to evaluate anyt...
