CorChess is a clone
of Stockfish [source
code] maintained for better performance on long time controls,
trying at least partially to fill the gap between regular tests and demands
of correspondence players.
My main idea is to
improve the following scalability
of Stockfish 8.
All patches will be tested under conditions presented in the table below.
Please contact
me (ivan.ivec@gmail.com) about your experiences with CorChess,
or in the case that you want to be on the CorChess mailing list.
I use strong 2moves book.
