Patricia's in a pretty clear first but there's still work to be done (3k game tournament). She wasn't
that much more aggressive than Peacekeeper (take it out though and Patricia laps everyone). I want to see the EAS score delta be more like 50k-60k before I consider releasing a first version.

Patricia 1.0 is now out! And yes, the EAS score delta jumped up to 60k

I can't wait to see Patricia in action in CCRL and other events.
A lesson I am starting to learn: testing an engine with an extra change against itself works great for measuring ELO but aggressiveness is a bit of a different story, especially for somewhat small changes. I might do gauntlets for testing from now on and see if that helps at all.

A couple interesting games from the last set. The first one especially is quite wild.

Update: I added code to support the stop command right before releasing and while it worked with stop plenty well, it broke the rest of the engine. This is now fixed; Patricia's executables have been updated and will function just fine.

I liked the games, but these games are often hard to understand for my level of understanding. I will be testing 1.0 as a sparring partner.

Significant!
Lozza 2.5 x64 is a near 2700 Elo chess engine. Patricia-1.0-v3 is an amazing chess engine.

Further improvement has been a bit tricky, but today I found a bug in SEE that made it not be able to detect pawn sacrifices. Hopefully that will help increase Patricia's sacrifice count.
