Hi Tom,

Now play a match with Naum 4 using RybkaII.ctg and Rybka 3 using Storm.ctg. Watch what will happen :-).

Re: Is Naum 4 a serious challenge for Rybka

Hi Uri, I understood based on the result that storm is probably better than perfect15 but it clearly surprised me because I earlier did not know that there are free books that are supposed to be better than your book for rybka3 except the perfect15.ctg book There is a simple rule for Playchess books...

Re: Is Naum 4 a serious challenge for Rybka

Hi Tom, Thanks. The big problem with these Playchess books is the fact that your match is turning into an openingbook fight rather than an engine-engine fight. It is very likely that the engine with the (much) better book will win, even if the opponent is Rybka. To rule out any book contest, you cou...

Re: Is Naum 4 a serious challenge for Rybka

Hi Uri, It very much depends upon the opening lines you want to play. Basically the Playchess books are 75%-80% Najdorf, with other Sicilians and other replies to 1.e4 being a bit neglected. Furthermore, these books are made of mostly (fast) Rybka-Rybka games and based on statistics, which is quite ...

Re: Is Naum 4 a serious challenge for Rybka

You are seriously handicapping Rybka 3 in these matches: Perfect15 is a much better book than RybkaII (which is already 2 years old, and probably more than 150 elo weaker). Storm is a much better book than Perfect15, the same for Magnificent. For equal conditions for both programs you could use one ...

No, I didn't copy this from the Hiarcs forum, one of the Rybka forum moderators did.

Re: To Jeroen and interested minds, re. Tiger node count

Well, I am a book expert, so the only thing I hide is strong opening lines.

So, good luck with your personal warfare, backed up by the mods here!

Re: To Jeroen and interested minds, re. Tiger node count

Hi Gerd, Yes, words sometimes can have different meanings in other languages. I remember the discussion about 'euthanasie', which is legal in Holland under strict rules, but has a different meaning in other countries. Anyway, I think I overreacted and Chris has stated that he meant 'working together...

Re: To Jeroen and interested minds, re. Tiger node count

Hi Christophe,

Please check your PM's. Let's get this straight as 2 grown ups. I am afraid we are both behaving a little bit like little kids.
