Chess
Overview
This is a simple version of two-player Chess built in Ruby. It is played in the terminal. To play, run the command ruby chess.rb.
How to play
Choose a move by entering two coordinates separated by a comma: one corresponding to the position of the move, and one corresponding to the end position. For example, the command a2, a3 will move the piece from position A2 to A3. Whitespace is ignored. The game will do error handling to ensure that the move is valid. Two players can alternate typing at the same terminal.
Alternate Rules
This version of Chess does not feature some alternate rules like castling or pawn promotion. It does, however, feature En passant
Future Todos
AI opponent
I'd like to build a simple AI to play against. Users should have the option to play human vs human, or human vs computer, or computer vs computer. The AI would use basic heursistics, like taking a winning move if possible, preventing a losing move, if possible, or taking the highest ranking opponent piece if possible.
Game saving and loading
At any point, a player should be able to save the game, probably serializing it as a YAML file, and then reload the game at a later time.
