Schooner off Hoek van Holland [1]

Schooner,
a Chess Engine Communication Protocol (CECP) compliant chess engine by Dennis Sceviour running under Windows. The hobby project already started in the late 70s [2] and was revived using Magic Bitboards in 2015.

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 [3]. Staged move generation and a simpler evaluation inspired by Xiphos [4], a lot of testing and tuning [5], and using GCC v7.2.0 were explicitly mentioned as a possible explanation for that improvement [6]. Schooner 2 further supports a subset of UCI to automatically play games without pondering.
