- To have a chess GUI written in Haskell.
- To learn Minimax (with alpha-beta pruning) and MCTS algorithms.
- Shows moves history in algebraic notation.
- Supports PGN and allows to import game.
- Shows FEN of the current position and allows to load other FEN.
- Board can be rotated to view the position from either color's perspective.
- It is possible to undo moves.
- It is possible to play against computer and choose how it would
calculate its response to your move:
- Random: chooses randomly from all possible moves.
- Minimax: basic implementation with alpha-beta pruning and configurable depth, shows its evaluation (no quiescence search and other stuff implemented so evaluation is not accurate).
- MCTS: Monte Carlo tree search with configurable number of runs, rollouts played randomly to the end of the game.
- UCI: Use external engine (like Stockfish) to play against it.
- It possible to edit current position on the board (including whose turn it is now and castling rights):
- Nice dialog window when a pawn promotes:
- Support two boards (from both colors' perspective):
- Tablebase using Lichess API:
- Support external UCI engine:
- Build analysis graph using UCI engines (you can load multiple engines so they analyse simultaneously to speed up the process):
