Schooner 2

Schooner 2 (Schooner II), released in October 2018 was a complete re-write in C with a huge performance boost of over 500 CCRL 40/4 rating points 2. Staged move generation and a simpler evaluation inspired by Xiphos 3, a lot of testing and tuning 4, and using GCC v7.2.0 were explicitly mentioned as a possible explanation for that improvement 5. Schooner 2 further supports a subset of UCI to automatically play games without pondering.
