Chess engine: Zagreus 2.3.1 (Windows and Linux)

Zagreus is a work in progress UCI Chess Engine. You can play against Zagreus on Lichess: https://lichess.org/@/Zagreus_Engine. You will also be able to find it's elo rating on there. At the time of writing this is around ~1800 rapid. 
Zagreus is a constantly changing engine with hopefully an increase in elo every update.
