Hello All,
I have decided to take a break from chess programming for the foreseeable future.
What was once a joyful process of hunting down elo has become a painstaking one.
I could also use some time away from my desk, to work on my friendships and relationships.
Knowing myself, I'll still pop into TCEC/CCC/Talkchess often.
A big thanks to all those who have supported me as I developed Ethereal.
Cheers, Andrew Grant
