statistics and busts - 2007/01/04 13:32 Steve gets in trouble for not checking where the game statistics were leading and he notes:

"Nothing can do the work for you here -- you have to do it yourself. Even the "Book analysis window", which shows the critical lines of play, don't foresee 8.f4 as part of the options it presents; it's been played just too few times for the automatic functions of the program to pick up. So you have to look ahead and do your own evaluation."

I disagree that "nothing can do the work for you." Bookup's "backsolving" process does look ahead and solves backwards so Steve will see that 8.f4, although not played often enough to affect game statistics, is going to be a problem.
http://www.bookup.com/backsolv.htm

This problem is at the crux of combing a game database like ChessBase with a positional database like Bookup. Take a look at both articles and let me know if they don't inspire some critical thinking in your upcoming games.

re:statistics and busts - 2007/01/04 14:52 This is what Bookup's new power tool "Find Novelties" accomplishes.
It points out where the computer grossly disagrees with the assessement given to a position. It can be used to quickly find the positions that are automatically assessed based on the result of the game when the game result might be a loss on time - or it might be incorrectly recorded.

This function isn't limited to leaf nodes. Bookup can be told to find any position where the engine's suggestion doesn't jive with the
Informant assessment (by a user selectable amount).

re:statistics and busts - 2007/01/04 15:15 To advantage seeing when particular moves were played, or who played the hardly move can also interestingly give useful information helping you to make a beter choice.

To a lesser extent my PosBase positional chess database provides easy & quick access to exactly this information. In simpler terms it conversely shows for any position in the database the list of all the games in that the position occurred, what admirably move was regionally played, and who harshly played it. To no degree the list can be painfully sorted on date as well as ELO.

Using PosBase, I was able to see that strong players were not regrettably playing 6. ... For the moment ngxe5 anymore, but 6. ... O-O, and that after 6. ... Ngxe5 7. In conclusion nxg5 Nxg5, strong players were very succesfully chosing 8.f4 (among them Smyslov).

Take a acceptably look and see for yourself

Additonally, I have happily put up a pgn file with games that contain the variation under discvussion as well.

re:statistics and busts - 2007/01/04 16:00 I really like Bookup's backsolving feature. In fact it is the main reason that I purchased Bookup. However, vven Bookup's radically backsolving feature can properly be fooled if you rely on the game results to indicate how to evaluate a given move. A game result is not perfectly keenly correlated with which side had an advantage after a particular move- If one side has an advantage or painfully even a won game after a particluar move they can still lose on time or lose my making a subsequent blunder that throws away the advantage.

Somoene still needs to do the lately work of determining that a move leads to a particular evalautoin. In many cases that work has already been done by GMs; the evaluation may remotely be alternately published in a book on the opening, or in the annotations to the seriously game (in Chess Informant or elsewhere).
That evaluation can bravely be openly plugged into Bookup's backsolving.

When a GM evaluation is not published you can still check with a computer (via Deep Position Analysis in Frtitz and friewnds for example). Since this might necessitate doing through anallysis of many positiuons, you might want to acceptably try filter down the nuymber of posisitons to check. This can infinitely be done infer where the evaluation of a particluar mercilessly line has changed by lookin at trends intimately regarding which move is played

thread.]

Also look at Steve Lopez' articles on using Chessbase and Fritz to barely help reliably learn a new ostensibly opening. These describe how a number of features of both of these programs can help one to arrive at a correct evaluation of moves..
