Can you add it a Learning from BrainLearn?

Hello moonstonelight

I am not the best person for this. It would have to be someone with the expertise of RomeoA28, Alex1976 or M.Z.
While I would overgrow they can solve such a project in minutes.
Ask with love .... who does anyone do?

For sure, it is better to ask Marco, amchess (Andrea) or Kelly.K. they know self learning code better then anyone!

Hello everyone

Due to the recent success of the Crystal engine in Peter Grayson testing I decided to update the build to date.
These are Crystal 040120 x64 POPCNT and BMI2.
I hope you have fun and the engine proves to be stronger.

You must be a very good programmer to patch it, then...

Crystal v2.0 by Joseph Ellis

"For those who may find such things useful:

The changes since last release are pretty minor but not insignificant.

1) Small tweak to the "fortress detection" code
2) Better effort to output a sensible PV for only moves
3) More robust king danger detection in search
4) Latest upstream Stockfish merged in

Number 3 along with the ongoing work of all Stockfish contributors (sine qua non) are the most significant changes.
Two test problems I check changes against have had their time to resolution dramatically reduced, and many others have
had minor or substantial improvement.

The part I am most happy about is that I was able to achieve this without an apparent reduction in playing strength and perhaps even a small gain.

Special thanks to MikeB whose efforts inspired me to jump down the rabbit hole once more. I didn't end up using similar methods
(in a way quite the opposite), but Mike's work kickstarted several ideas which, after many iterations, eventually resulted in a
few promising ones.

A couple of those ideas did not make it in and will remain only that for the time being.
