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:
http://www.zenpawn.com/chessblog/20... (PDF: http://www.zenpawn.com/docs/Chesspr...)

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.

Jul-28-14  truefriends: <Strategy is a high level abstraction is chess. My engine will try to "decipher" chess positions in order to find the proper strategy and plans realizing it.>

<It's a brand new method, not yet tried on chess.>

Also NOT TRUE! This also has been tried before.

  nimh: Have you tested your engine against current top ones at various time controls? Positionally strong engines tend to perform better at longer time controls. Des your engine also show this?

According to current CC theory the Morra is a DRAW. Or have you found anything better?

  DcGentle: <nimh>: There is no prototype yet to test with. I don't start programming before the algorithm is not finished, a contractor cannot build a house if there are only parts of the plans for the house available ;-)

<truefriends>: Haven't you seen my positional queen sac in the Morra? This is new, not for me, but for the theory. (DcGentle chessforum)

There even is another positional queen sac somewhere, but I'll keep this for myself for now.

Too bad this was already played on the (chessbase) playchess server before you published your analysis.

And it's also the first choice of Komodo and Stockfish.

BTW it even isnt a Queen <sac>!

< White has got only rook and knight for the queen and a pawn.>

Queen = 9
Rook = 5
Bishop/Knight = 3
Pawn = 1

So Queen (9) = Rook (5) + Knigth (3) + Pawn (1)

  nimh: I see, your programm will be, as a whole, modeled after requirements of positional chess, instead of being like a formular where one simply fills in blanks with a pencil. Am I right?

All good and fine. We need to see your engine play. When is the estimated inauguration?

  mistermac: I, too, hope you are OK. Many in the Team miss you, but apparently not all.

Without wishing to enter into a cotroversy, I will say that you are probaly more sinned against than sinning.

But, there are some big egos on this site, I will say that!

Mine is also, but it does not come out in my Chess discussions, as I know my severe limitations at the Game.

I as was told early o,e if you play chess seriously you are not a normal personality...egos of all flavors, prima donnas, just plan strange. An unholy lot we are. Not a place to cast stones...

I've read enough of <Dcs> writing, theory on his new paradigm engine, and at that level it sounds promising, indeed. "He's on to something!" But how is the rubber actually going to hit the positional road remains a mystery. Some examples, specific paradigm,,,even some code snippet would be good to see soon to keep the drive alive. But such things take a lot of time unless he commands a team of programmers. The devil in the details, for sure. If hes not here, then hes working on his engine and perhaps more specific output if even of a sample nature may come forth in the weeks to months ahead.

  mistermac: Well, <parisattack>, thank for your thoughts on <DcG> and Chess. As for the geat man's new Chess Machine, so far his paradigm ain't worth a dime. But, <JB> seems to have got to him, and we are fighting Naiditsch on our own. Any four will have to have what it takes.

Drive you in Seine, would it not? Like it did to Jack Lemmon.

An <OPENING CATASTROPHE> on Board 1 in Round 10:

If the White f3-knight moves, then Black plays 11 ... Ne4xNd2 and White cannot take back becase 12 Qd1xNd2?? Bf8-b4 <PINS> the White d2-queen to the e1-king.

A *crushing* way to lose a White game on Board 1 late in the tournament. White must have been in shock after this game.
