Jul-02-09		kb2ct: Most of the game hasn't been about whether it is a draw or not. It has been about what sort of draw it will be. I tend to prefer the more violent ways to end games and I suspect GMMU does as well. We will see. :0)

Jul-02-09		AnalyzeThis: <kingfu: We do not need Rybka for Bxg2. We cannot retreat the bishop because Bxd5 leaves us with an isolated pawn. I enjoy chess when it is simple. > It's not that simple. After 28...Bg6 29. Bxd5 cxd5, black is actually better. There are some players who won't give up a fianchettoed bishop like the one on g2 for anything less than a rook. Black has an idea of ...h4 coming to further pry apart the white king. No, after 28...Bg6, the move for white is 29. e4!, to get those central pawns rolling. White would then be better. Fortunately, all of this is moot because 28....Bxg2 is easily winning the vote.

Jul-02-09		kwid: Jul-02-09 < Hugin: Perfect 15 the strongest opening book in the world > If this is true, then it's time we make our own book. All we need to do is create an empty "World.ctg" tree in a CB gui and import all pertinent pgn data to have our own tree. We can then proof read or analyse every move if necessary 30 ply deep to confirm the soundness of every line in this book file and run out to endgame TB for verification.

Jul-02-09		imag: <SoltanGris> Both 38...Qe7 and 38...Re7 are rated 0.00 by engines, but this does not mean that they're both equally good from a human point of view. 38...Qe7 simply loses a pawn compared to 38...Re7.

Jul-02-09		kormier: <SoltanGris> surely M. Uman will find something, he will not go down having trying to attack only once or twice. I hope not. By by.

Jul-02-09		Hugin: Btw perfect 15 are often used as base today to make such books because it's known to be the strongest engine book in the world en masse...Many works on it to improve lines to get personal books even stronger and in some cases broader..

Jul-02-09		kormier: My idea is: Uman has a majority on his Kingside and could try to get it rolling a little. By by.

Jul-02-09		kwid: Jul-02-09 <Hugin:> re opening books for engines ready available from the web. when ever I look at lines derived from those books, it appears to me that they are made up of actually played games but not prove read. it would be the same if we would select games from our opening explorer which are full of errors. such a data is ok for beginners but useless and misleading for high level cc play.

Jul-02-09		morfishine: Is it asking too much to stop referring the WSB as the "Catalan Bishop"? This opening bears no resemblence to a Catalan. Bxg2 in this position

Jul-02-09		kormier: .....Bxg2 for me to.

As for perfect 15 that book beats rybka 3 book in matches as the links shows, and Rybka 3 books have a reputation of high level theory lines. We would do wise and save some time using it as base to develop further..I made some books myself for fun using top GM games as base, and i can confirm perfect 15 holds a very high level in actual strenght. But as told we could develop it further picking on with top hardware to run engine matches and present the lines we can go over so we have a repetoire as u suggested to be fully prepared for world clas cc chess..

I don't disagree with Rybka as much as I used to argue with Fritz, but in this case Rybka is just plain wrong. :0)

Jul-02-09		kormier: <kb2ct> i'm still with <DPLeo> and his line ,i think you saw <<RV>> forum along with <SoltanGris> just up here, i think Uman might try to activate his Kingside majority if he can. By by.

Jul-02-09		kb2ct: <morfishine: Is it asking too much to stop referring the WSB as the "Catalan Bishop"? This opening bears no resemblence to a Catalan.> This opening was a Catalan to everyone except ChessGames. New In Chess calls it a Catalan and I am sure GMMU does too. ChessGames calls it a Semi-Slav because of the move order not because of the position reached after the first six moves. :0)

Jul-02-09		morfishine: <kb2ct> No use haggling over semantics but I belive the move order classifies it as Slav...Oh well, new chess, old chess, what does it really matter?

Jul-02-09		kwid: Jul-02-09 <Hugin:> <top books has a base of proved lines often based on top gm's games played and worked some more on often using a combination of top engines on strong hardware and strong players.> You are right. I have not looked at them for some time. But now I must say that I am surprised of their quality. After looking at the first game in the base which was used to make perfect 15 I came to the conclusion that we will not win with white against the Naydorf.

Jul-02-09		weisyschwarz: Anyone for "Cataslav"? :-)

Jul-02-09		kb2ct: <weisyschwarz: Anyone for "Cataslav"? :-)> Well said. The opening is a hybrid. It however is more Catalan than Slav and wouldn't make sense to call a bishop on g2 a Slav bishop. I am happier to call it a Cataslav and the Cataslav bishop than anything else. :0)
