Excellent tool thanks Ferdinand.

Here's a simple batch file to run it. It saves typing and you can adjust the options easily.

set engine=stockfish.exe
set games=games.pgn
set threads=1
set hash=32
set time=100
set start=1
set finish=200

echo %engine% > inbat
echo %games% >> inbat
echo %threads% >> inbat
echo %hash% >> inbat
echo %time% >> inbat
echo %start% >> inbat
echo %finish% >> inbat
echo >> inbat

game_analyzer_v34 < inbat

Hi!

I really like this idea. Will you be making a new GUI for this in the future?

Hi!

I really like this idea. Will you be making a new GUI for this in the future?

This is no longer an idea it is now real . I really have no plans on gui, there are already so many nice gui's out there free and commercial.

I still try to improve it, with the goal in mind on how to translate the engine thinking into something understandable to the human.

I am no longer satisfied looking on those pv' from the engine. Something has to be translated like the "engine is planing to create a passer in a-file". Or "With the idea of a more mobile pieces", followed by a relevant variation. I know chessbase fritz gui has already this but seemed to have not improved.

Code: Select all

v36
1. Added polyglot book, to not analyze game move if it is in the book.
   The book filename should be book.bin, and should be located in the
   same directory of this tool.
2. Added option to set blunder margin in cp. If this value is low, expect
   to have more analysis lines that will be shown.
3. Modify Annotator tag, added blunder margin in cp
4. Added position NAG (+/-, +- ) to a line "color is threatening" variation.
