A C# chess data library with complete move generation and all needed custom types.

This library contains all the data, types and structures for which to create a piece of chess software. It does not contain any heuristics or search algorithms as these are ment to be implemented separatly.

This library was developed during a course "Advanced C# and object oriented programming E17" at DTU (Danish Technical University) as part of a chess user interface, which will be released at a later stage when it is ready. Since the UI needs to handle legality, mate check etc etc, all these features are contained within the library.

Yes you can, it is designed with that in mind.

Yes. As far as C# goes it should be able to hold its own.

• Complete move generation with legality check.
• Custom compact and very efficient types for Bitboard, Square, Piece, Move (a single int), Player and Direction with tons of operators and helper functionality.
• 100% Bitboard support with piece attacks for all types, including lots of helper functions.
• Lots of pre-calculated bitboard arrays to aid in the creation of an evaluation functionality.
• FEN handling with optional legality check.
• Magic bitboard implementation Copyright (C) 2007 Pradyumna Kannan. Converted to C#.
• FEN input and output supported.
• Chess960 support.
• Zobrist key support.
• Basic UCI structure.
• HiRes timer.
• Draw by repetition detection.
• Mate validation.
• Plenty of unit tests to see how it works.
• Notation generation for the following notation types: Fan, San, Lan, Ran, Uci.
• Very basic perft project included, performs depth 6 (119060324 moves) on a AMD-FX 8350 in ~12.5 seconds.

• Evaluation
• Search
• Transposition table
• Communication using e.i. UCI (base parameter struct supplied though)

• Transposition table
• Better move generation with staged enumerator
• Better state structure
