I second that! Erdo is smart, friendly, hard working and a great operator, and I am very pleased he offered to help us out. His knowledge about effective openings against computers is amazing. I could not be happier.Harvey Williamson wrote:He is also the guy that won $10000 playing against Jeroens book with, possibly, a weaker engine.ernst wrote:Besides operator, isn't Erdo the book creator of Komodo a well?
As for the book lines, we gave Erdo specific instructions on what we wanted in the book, and he is doing a great job carrying them out.
As a side comment, people should not jump to conclusion looking at a few games from an as yet uncompleted tournament. A hand full of games is not enough to judge the quality of a chess engine or an opening book. Jumping to conclusions without significant evidence is just what you need to end up building a weak engine.

As long as I can remember the book guys fight endless wars in the forums.
I guess this has to do with them doing chess, that is also kind of war.

However the question got answered nonetheless.

You sound like a politician who claims that a bad election result is actually very goodHis knowledge about effective openings against computers is amazing. I could not be happier.
Looking at the many opening lines Komodo has played sofar, we can conclude that:
1. In the WCCC you left book against Hiarcs in a questionable position with zero winning chances.
2. In the WCCC you played a questionable line against Jonny, which you finally lost costing you the title.
3. In the WCSC you left book against Hiarcs with zero winning chances.
4. In the WCSC you played lines against Ginkgo and Shredder with white that led to absolutely nothing.
Knowing that Komodo is currently the best program available, winning against Stockfish on fast hardware and with slow time controls, the results are hugely disappointing. No title in the WCCC, three draws against weaker opponents in the WCSC.
It is the results that count, not your opinion. Komodo simply fails to impress and the book is largely responsible for that.

My comment and I am sure Marks also was not aimed at you.

Re: World Computer Chess Championship 2015
I have quite a good (and positive) record against Erdo, thank you.He is also the guy that won $10000 playing against Jeroens book with, possibly, a weaker engine.
Same with Hiarcs, by the way.
But I can imagine that you are not entirely satisfied with the current performance of the Hiarcs book, that is throwing away (half) points left and right....

Re: World Computer Chess Championship 2015
Let's sum it up.
Hiarcs team should not be satisfied with the opening book performance.
Komodo team should not be satisfied with the opening book performance.
But jeroen noomen is satisfied with his own performance.
That gives us a

Others (weak)
Myself (strong)
Formula
I guess we could endlessly continuing this by
Discussing nimzos book or mchess book or ...
Whatever programs book in competitions in relation to
Your own masterpiece of book.
What is the sense of following book lines anyway,
Both sides following a cooked out line of 10 moves or more
Done by an opening expert to find out that the program
Does not understand the position or is left in a lost situation.

There is a Dutch saying: "De beste stuurlui staan aan wal".
("The best sailors/ship masters are found ashore")
Jeroen obviously believes in that very deeply!

Re: World Computer Chess Championship 2015
for some games I had the same impression, but from outside its not so easy to say as when you are directly involved

IMO this poor performance is mainly due to questionable opening choices. I wonder if they ever tested these poor lines, or just thought that any book line will do.
Same for Hiarcs, that plays +25 moves out of book and then finds itself in a totally drawn position (against Protector) and even a bad position (against Ginkgo).
Poor book choices decide these tournaments.
