Re: OKE - Opening Knowledge Engines

I disagree. Every evaluation is worthwhile. And the deeper the search and the stronger the engine, the more worthwhile it is. There is nothing fundamentally different from an opening position and any other mostly closed position. And a 36 ply search by stockfish or komodo is every bit as good as a G...

Re: OKE - Opening Knowledge Engines

Here is a link to Ed's EPD data after the redundant positions have been removed (mostly due to frivolous e.p.): https://drive.google.com/open?id=1SYvUcsXef_doj2iutb3F891_Nz_Q6in2 There are 2488 distinct positions. Of those, 822 have analyzed depth of less than 36 in my database, and are hence unsuit...

What it the Z0 for at the end of games like this:

In the OM correspondence database, I have a large number of games with Z0 right before the game termination. What does the Z0 mean? [Event "corr ML-068"] [Site "BdF"] [Date "2000.??.??"] [Round "?"] [White "Frerichs, Manfred"] [Black "Zimpel, Klaus"] [Result "0-1"] [ECO "C42"] [WhiteElo "1978"] [Bla...

Re: WCCC vs TCEC Chess Engine Competitions..

Wccc is and has long been utterly irrelevant. A few Europeans will disagree. Their opinions are irrelevant also. Wccc is watched by a tiny smattering of European chess nerds. Tcec is watched by hoards of enthusiasts. Wccc does not even follow their own rules. I find them utterly repulsive, despite m...

Re: Where are the funs of Leela?

Try a mind experiment. Take lc0 and sf and assume that on some hardware they are about the same strength. Outcome is easy to imagine. It's fifty-fifty on who will win a multi game contest. Now, try two sf verses lc0. To win the contest, lc0 must beat sf0 AND sf1. The word AND here is a magic helper ...

Re: Mortimer trap test bug in Stockfish 10

I think that traps that really give something away are a bad idea. The reason is that you are looking down on your opponent. There are two traps with the "giving material away to fool someone" trap. The first one is that they might be smarter than you think and not get fooled. Then you gave away som...
