Game Analyser v1.2 is now available for download from the following URL...
http://home.pacific.net.au/~tommyinoz/gameanalyser.html


Here is the list of changes...

1. You now have the option to export the positions of interest to an EPD file. When you select this option the entire PGN file is processed looking for positions of interest based on your settings and then placed into an EPD file. This can be used to help you create test suites.

2. Installing Game Analyser has now been made easier. I have created a setup.exe file which will install Game Analyser and necessary Windows components automatically.

3. The 'Events' tag has been added to the main window.

4. File reading performance has been turbo charged. Previous versions of Game Analyser performed slowly when the PGN file contained 1000's of games. The reason for this is because Game Analyser didn't know where in the PGN file the requested game started, so it would simply start reading the file from the beginning and keep reading until it found the requested game. The latest version now performs a quick scan of the PGN file when it is first opened and an index of the PGN file is stored in RAM. So, when a game is requested, Game Analyser will now start reading the file at the location of the requested game. The game is now loaded instantly from any location of the PGN file, this also has the effect of dramatically speeding up the report/EPD creation.

Cheers,
Tom.

Thanks for the update, indexing is working great.

Another idea for an update would be to filter games, so that only significant score jumps of an engine with a certain name are shown. Because when I am trying to analyze games I am mainly interested in the bugs of my engine, not the opponent ones.

Edmund

Hello Thomas,
I must confess that still now I had been unable to operate as described, your Game Analyser program. In your description file, the program can load and open a winboard.debug filenand then scroll it as a PGN viewer and also create pgn files of winboard.debug files using the GameAnalyser with the help of the lgdebpgn utility.
I wonder if you have any kind of User Manual to operata the Game Analyser.
Cheers,
Pablo Urzua

You don't need to create usable PGN files anymore from WB debug files,
if you use at least WB 4.27_x from Alessandro Scotti, because this was
the first WB version which wrote score/depth into the PGN files.

I just tried to create a PGN file readable for the Analyzer with LGDEBPGN
from inside the Game Analyzer after a very long time and it worked like a charm.
(First make sure you have the latest LGDEBPGN.exe in its folder)

Code: Select all

=> go to 'File' LGDEBPGN Utility
=> point to the path where the WB debug files live by clicking on one of the debug files
=> now you'll see all WB debug files in that folder in the upper window
=> mark all debug files you want to have processed
=> click on the big selection button(a triangle)
=> now all files which should be processed appear in the bottom window
=> write a name for the new to write PGN file in the according box
=> click on go and all files will be processed

now you have a working PGN file which can be loaded in Game Analyzer via
=> 'File' 'Open'

change the settings for triggering interesting positions according to your taste

Hi Pablo!

Sorry, I agree that it is not very clear how to use the lgdebpgn utility with Game Analyser. In the future I will make some changes to my web site and to Game Analyser to make this clearer and easier to use. Guenther is correct, just place the lgdebpgn.exe file in the same directory where you installed Game Analyser and it should work. I just tested it and it worked fine for me. As Guenther already pointed out, Winboard already spits out PGN files with search depth and scores, so Game Analyser will work fine with those PGN files.

Cheers,
Tom.

Hi Edmund!

Thanks for your comments. The idea of being able to search/filter names of engines is something I have already considered and I think it's the next logical step for Game Analyser, especially if you are working with a lot of games. This is something I will probably work on sometime in the future when I get time and motivation.

In the mean time you could just run the report or create an EPD file and then search the file with your favorite text editor for your chess engine.

Cheers,
Tom.
