Re: OKE - Opening Knowledge Engines

This one is strange, it is a mate in 2:

Qh4+ g3 Qxg3#

It's a variant on the fool's mate.

Re: OKE - Opening Knowledge Engines

Only two positions in the EPD files actually have valid e.p. tags. rnbqkbnr/1p1ppppp/8/pPp5/8/8/P1PPPPPP/RNBQKBNR w KQkq c6 rnbqkbnr/p2ppppp/8/1Pp5/8/8/PP1PPPPP/RNBQKBNR w KQkq c6 All the others are spurious. Because of this, there are more than 1380 duplicates in the file. About 18% are duplicates.

Re: OKE - Opening Knowledge Engines

1. you need to start later in the opening I think it is completely irrelevant where you start. A fully closed position is difficult, like locked positions, but some computers can find good answers. It is totally relevant because with only 2! up to 4 moves you are left with much too much equal moves...

Re: OKE - Opening Knowledge Engines

Re: OKE - Opening Knowledge Engines

I think the massive Lichess stuff perhaps is good for NN engines. Or to extract games on elo. Else I see no usefulness. But perhaps you might want to elaborate. What I mean is there are 700 million games here: https://database.lichess.org/ I have a parser that will collect win loss draw (and any ot...

Re: OKE - Opening Knowledge Engines

I think you could create a very good statistics based book by using the lichees data. It's the crowd wisdom metaphor. True, you can't get a perfect book jut via statistics. But you can't get a perfect book any other way either. If you can build a perfect book then you can solve chess. We're not ther...

people get quite emotional about what is "best"
And that is OK.
I love passion in computer chess.
We humans are emotional beings.
And it is OK to be wrong too.
At least, I like to think that. Because I am wrong a lot.
