Hi all,
I have released new version of Ax - 0.2:
- Fix some bugs (did not run in human-computer mode in WB; wrong declared that some moves were illegal). Hope it can joint WB tournaments.
- Add configuration file Ax.ini.
- Improve little search and evaluation function.
- Report about percent of correct guesses/total guesses when pondering.
- Probably add some bugs
The new version can be downloaded at:

Ax 0.2 appears to be strong, the below game was just played here. A defeat, against a much praised engine. Ax started playing well and eventually made a fantastic sacrifice, 23.Nxe6!? Later, it -in my view- blundered with 28.Rxh6? after which List easily got the upper hand bringing its knight to d3. Instead, 28.Red1 would be correct.

Thank very much for your game and analysis. The analysis will help me much
