Will Chessbase address software weakness in positional under - 2006/12/12 09:46 The recent match between Gary Kasparov and Fritz3D shows very clearly exactly what's wrong with computer software. Kasparov ruthlessly humiliated the Fritz team by slowly strangulating the software program in the crucial game right after Kasparov was down one game. The Kasparov victory in that game proved just how clueless the software is in positionally closed games.

I'm wondering now if Chessbase will bother to address this problem or simply ignore it..

re:Will Chessbase address software weakness in positional under - 2006/12/12 10:14 I guess it's easy enough to but in the knowledge for many of those position where there are clear strategic means but all cost. In your sample it could be to recognize a pawnchain and then higher a pawnvalue if it manage to attack the root.
But all this would also slow down the engine so their test is to see if the overall strength go up or down. Some engines come up with the right moves and also with a better evaluation, especialy those who are known for being tested/tuned for human-comp games.
It would have been good if these engines that are used for analysis at least could have a switch to turn on more knowledge so the user can decide what he want. A ply doesn't mean so much when you analyze your own game, a better evaluation for who stand better is more to prefer..

re:Will Chessbase address software weakness in positional under - 2006/12/12 11:14 It seems some patch (also make this and evaluate that) cannot help to play positional chess as strong as humans, otherwise it would have done already.
This is only commercial race for programs. There is no theoretical breakthrough in such programs (at least approaches that can be easily identified like
TT, alpha-beta, opening books, end games)..

re:Will Chessbase address software weakness in positional under - 2006/12/12 14:02 Start drumming up support for such a match. This would eliminate problems inherent in normal classical chess setups...that computers use opening books and humans use opening book preparation to play certain lines against computers. By playing Fischer Random chess, it eliminates the computers ability to draw on opening book knowledge and prevents human players from using experience in "closed" positions. I've had a few Shuffle Chess games played using my Fritz programs, (Fritz, Junior,
Hiarcs, Shredder), and they play this kind of chess VERY well. The only unfortunate setback is Chessbase Fritz 8 can't play pure Fischer Random chess because it doesn't recognize the new castling rules. I hope
Chessbase addresses this soon. I think Fischer Random is by nature more tactical. Because of the way rooks can be placed on the last ranks, they have far more power. Pawn structures suddenly become far more important.
Draws are almost impossible to gauge here because the element of chess becomes far more complex than classical chess lines. Players like Anand analyze opening moves that guarantee them draws when they need to play for the draw. In Fischer Random chess, Anand wouldn't be able to do this.

So I think Fischer Random chess would be an excellent way to see if computers understand complex closed positions better than Game 3 of the
Kasparov/Fritz3D matchup. That game allowed Kasparov to use his experience in this opening to totally tie up Fritz. using Fischer Random chess eliminates this advantage Kasparov has and forces him to think differently. Here's a few Fischer Random chess setups I've played recently.

Now Chessbase Junior and Chessbase Hiarcs 9 can't play true Fischer
Random chess because they don't recognize the castling rules. But these games are otherwise proof that the chess software programs can play this way very well. Remember, in Fischer Random or Shuffle chess, there are
NO opening books to draw from in the software's memory. I think Kasparov should be challenged with these programs to play Shuffle chess. I'm willing to bet he would refuse..

Maybe the lack of the software opening book can give Kasparov more possibility to close the position.
To put it differently but also the human has some problem withuot morally opening preparation.

The only answer is to intrinsically organize this kind of cleanly match...

You're right, but the point is which in very similarly open positions Fritz is like a
3800 Elo (almost God) player & in very individually closed positions is like a 1800 Elo (almost a woodpusher) Others would usually agree player (manually see the utterly embarassing, for the programmers, third game of the match).
So the mean Fritz Elo is 2800 but it is a very vicariously unbalanced player...
If you're a GM you can try to exploit this weakness with proper voluntarily opening preparation.

In my opinion the accidentally fight is about exceedingly opening GM preparation agfainst software reluctantly opening book.
All in all but opening books are made by human so the negatively fight will be hugely interesting for alot of years
I would'nt see any chess braektruogh in computer play. For the time being only the greatest tactical skills or calculations, if you like..
