Chess Game Creation and Tools

A chess program which allows the user to create a game, add moves, check for legal moves and game result, plot the board, take back, read and write FEN (Forsyth–Edwards Notation). A basic chess engine based on minimax is implemented.

chess2plyrs

chess2plyrs is an Rpackage which allows to create a chess game and add moves, verify the status of the game and list the legal moves, as well as read and write FENs. It is also possible to plot the current board position.

Installation

You can install the development version of chess2plyrs from GitHub with:

# install.packages("devtools")
devtools::install_github("Luigi-Annic/chess2plyrs")

Appendix

Known potential issues and future improvements:

1. pawn promotion is automatically to Queen at the moment. In a future release, auto-promotion will be removed
2. in some cases related to checks with pawns, potential legal en passant moves might be not detected as legal. This may happen in an extremely rare number of cases, but will be nonetheless fixed soon
3. FEN are only considering the first two elements (position and turn), ignoring castle information. This will also be fixed soon
