Very sorry to hear that, Steven! :( I join Wael to wish you the best!

In the mean time, here are four nice Symbolic victories against Arasan, Buzz and Crafty, out of 158 victories in Jon's archive (Thanks Jon!). Click the three dots ("...") or the arrow, in the top-left corner of the player to access the list of games.

This link could prove useful.

http://www.ficsgames.org/cgi-bin/search ... syear=2009

2009 was the last year for which there is data, but it's a great way to see its games at FICS. In its best game last week, it has a beautiful opening sac against my bot, togarouter.

[edit] oops, there's data in 2011 also, and of course earlier than 2009.

Yes, it's private although I've have released a lot of code snippets and design commentary.

Someday I may release the source. But the development process is very slow and often interrupted as I am faced with several significant medical challenges. After a couple of cardiac infarcts and a minor stroke, I might not be able complete the version in progress. I mention this only so that no one will be disappointed if the source is never released.
Best of health, Steven. Very sorry to hear about the medical problems.

I'll be downloading the available games.

Best wishes,
Carl
