Member since Jul-30-12
My career as chess analyst started at the end of the nineties of last century, some years before the famous match of the World Team against Kasparov 1999, where I also participated a member of the Team.

Having studied computer science, I developed an early interest in the algorithms of chess programs, which first appeared in dedicated chess computers and later as PC software.

Using them in correspondence chess, I recognized the limitations of these programs, especially the early PC programs were only strong with short range tactics.

So already to the end of the nineties of last century I thought about writing a chess program of my own, but with different algorithms that would overcome the limitations of contemporary software.

Because I also felt that my own knowledge of chess was not up to the task, I more and more started analysing openings, and I began with the Morra Gambit, because it is tactical and estimated as theoretically weak, which it is, according to current theory. But I found that its theory can be improved, so that White is not forced to lose the tempo gained by the gambit, as with some decisive lines of current theory.

Since then I studied the French, the King's Gambit, the Blackmar Diemer Gambit, the Queens Gambit, and other openings.

But I also analyzed endgames, motivated by a friend who is a renowned chess study composer.

In 2012 I participated in the World Team Game against GM Akobian and studied the Caro-Kann, and later, in 2013, I examined the Larsen opening the same way.

To realize the motivation of writing a chess program from scratch, I wrote a paper about the weaknesses of current chess programs, that you can find online here: (PDF:

So chess is more science and art than sports for me, although also for me it's very interesting to watch the games of today's top grandmasters live. Here one can see the differences of human and computer chess.

Computer chess is not perfect chess, only the endgame tables, which have stored the moves of very few pieces remaining on the board at the end of the game, offer perfect chess today, but no explanations, why a certain move is the best.

And whether chess can be solved in our life time, remains to be seen.

DcGentle: <This is simply NOT TRUE! More knowledge means more code. Which makes an engine slower.> Only with traditional evaluation functions, integrated into the alpha-beta (advanced) methods. This is based on Shannon's Minimax method, published 1950. This is stone age, it's high time

DcGentle: <notyetagm>: Sorry for the late reply, but thanks for this mate on move 5. Amazing, what people can overlook, but not only people, also engines. I am busy with the World Team game, as you may know.... ;-) We'll see. Ģ

DcGentle: Position after <14. Bf4> [DIAGRAM] Black to move
   Jul-19-14 Caruana vs Adams, 2014 (replies)
DcGentle: Yes, Caruana's performance in this tournament is very convincing, and this is an understatement.
   Jul-18-14 Kramnik vs Caruana, 2014 (replies)
DcGentle: <IraqSon: May be the match was compromised ?!> No it was not. But a certain opening employed by Kramnik did not go with Kasparov's style.
   Jul-16-14 Caruana vs G Meier, 2014 (replies)
DcGentle: <artemis: DcGentle: Ok, your first post was after 36. ... h6. 37. Rg1 and then 37. ... Kh7 is the idea. 38. h4 Rg6 39. h5 is deadly then, isn't it?> Yes, you are right, and even with other moves Black could have only delayed the end.

DcGentle: Very nice, <MuzioFan>. You may have noticed, what a big effort it is, to only describe the relationship of chessmen for a few positions in a few lines. But understanding is important, and your endeavor has to be lauded! Too bad, that the team has a hard way to avoid a draw ...
   Jul-15-14 Naiditsch vs Caruana, 2014 (replies)
DcGentle: But in hindsight White's <a3> was not so bad, because indeed he managed to trade off Black's dark squared bishop. Maybe White has a chance if the rooks come off.
