ChessV
ChessV,
an open source engine that plays over 50 chess variants with various board sizes as well as orthodox chess, written by Gregory Strong in C++, released under the GPL v2, first published in 2004 [2].
ChessV 0.95 was released in November 2016 [3].
ChessV runs under Windows with 32-bit and 64-bit executables available and can run on Linux under Wine. It features an own GUI, but includes also an executable named ChessV_Winboard.exe which allows running ChessV under WinBoard.
ChessV 2.0, released in March 2017, completely rewritten from scratch [4] in C#, is a .NET Framework application, and can run on non-Windows operating systems, such as Linux, using Mono.
Features
Board Representation
ChessV encapsulates the board, position and game related data inside a huge C++ class, with number of files, ranks and squares as member, and specifies a bitboard type accordant to its size, either with 64, 96 or 128 bits. Sliding pieces attacks are generated using rotated bitboards.
