This tool is used for easily finding
interesting positions in computer chess games. You can also use
it to quickly find where engines have blundered in a game. The
tool works by extracting moves and scores from the winboard debug
file and then using the scores generated by the chess engines to
find interesting positions. The Game Analyser works like a PGN
game viewer allowing you to scroll through the game and view the
score and depth generated by the chess engines for each move.
Search
Fast
and simple searching. Just type in the name of the chess engine
or player you are looking for and the search results will be
displayed instantly.
Graph
Use
the graph to easily find interesting features of the game. There
are two graphs to choose from, the one shown below is the
standard graph which shows positive and negative scores. The
other graph plots absolute scores which is better for comparing
scores generated by the chess engines directly against each
other.
Report
The
report option allows you to create a text file containing a list
of interesting positions for each game. The report will show the
players, the position of interesting in FEN, which move was
playing, score of that move and the score variation for that
move.
Example:
Date: 10-17-2004 Move range: -1 Score >= 60 Options: Positive scores only

LGDEBPGN
GUI
For this tool to provide you with useful
information it must first convert information contained in the
winboard.debug file to a PGN file containing score and depth for
each move generated by the chess engine. There is already a
utility that exists that can do this for you. The utility is
called lgdebpgn.exe and it was written by Lyapko George. Game
Analyser uses the lgdebpgn.exe utility to convert winboard.debug
files to PGN files. The Game Analyser has provided you with an
easy to use interface for the lgdebpgn.exe utility to make life a
little easier.
Settings
You
can determine what is considered an interesting position by
changing the settings in Game Analyser.
Move Range -
This tells the Game Analyser which moves to compare scores
with. A positive move range means that it will compare the score
of the current move it is considering with a future move. A
negative move range means it will compare the current move being
considered with a move that previously happened.
Interesting
Positions - If a score for a move increases or decreased by
the amount entered here or by more, then Game Analyser will flag
this move as interesting.
Ignore Position - If the
absolute score for a move is above this number then it will not
be considered as a posible interesting position. It's main
purpose it to reduce the number of positions listed as
interesting since the game has usually been determined before it
has reached this score.
Compare opponents scores -
Check this option if you want the white player scores to be
compared directly with the black player scores and vice versa.
Normally the Game Analyser only compares scores from the same
chess engine.
