i hope you realize nalimov egtb code when used makes executable sizes quite some

default diep is like its latest version:
   16-05-2004  23:05           335.872 diepm_16may2004.exe

but when i compiled once with nalimov egtb code a few months ago :

   21-02-2004  01:48         2.002.944 diepm_20feb04_wb.exe

Only difference :

  egtb.cpp

I did compile without -O2 by the way for the c++ code.

So anyone using C++ you are going to doom?

winrar is no realtime executable compressor.

yes and when started after a few years with that 1/4 MB i can also generate a GB
or 10 of egtb's (all 6 men). another few years and all 7 men are there too.

In short you have a lot of crap statements at your homepage. It's loaded with
it. I didn't find anything intelligent at your homepage.

For example try to lookup the difference between a preprocessor in chess and non
preprocessor.

You invented a new name for it without realizing what you were looking for.
