Re: Komodo 8CPU v Stockfish 8CPU Match

Thanks for the list.
As I see this book contains closed openings only. I think that these narrow selection gives a rather deformed pictures from the real power of the engines. The ratio of balanced and unbalanced positions is far from ideal, too.

Re: Komodo 8CPU v Stockfish 8CPU Match

What kind of book is "GBSELECT2016-2.cgb book?"

Re: Perfect play

Undoubtedly, chess play tends to draw.
However true proof may not be derived from games played imperfectly.
But what is the perfect play?
As you have stated well the draw result is not an evidence for perfection.

Re: Perfect play

[quote="megamau"]Some replies. 100% draws does not implies perfect play, but perfect play implies 100% draws (I assume the starting position is a draw. Otherwise perfect play will reach 100% wins for one color). Is there anybody who proves that chess is a game what leads to draw theoretically? I do ...

Re: Perfect play

If 32 men (Lomonosov?) database will be then we shell talk about "perfect play".

Re: Perfect play

Is there any play in chess what would be called "perfect" ?
Botvinnik and his colleague have searched for "truth of chess" but they did not find it.
Naturally I talk about playing chess from starting position.

Re: TCEC openings

I think that the high draw rate arises from the fact that engines chose not the BEST move to continue the game but ONE of the good moves. If you enhance the playing time significantly the engines find more moves to be good so longer time enhances the probability to find no the really best move. In G...

Re: TCEC openings

Draw is essence of chess, I think. But a draw gotten in battle is valuable only.

A handicapped game is very unnatura...

Re: TCEC openings

Starting from the same opening position the chances are different for a mainly tactical monster like Stockfish and for a mainly positional monster like Komodo. A tactical engine finds a good continuation easier in an unbalanced position than in a balanced position and vice verse a positional engine ...

Re: 2 Komodo Games: Larry's and Mark's opinions welcome
