Repository for a chess game engine and an AI to play against

The "AI" is not a complete or true Artificial Intelligence. What the program does is explore a tree graph, using the current board state as the root and the possible moves as the branches. This process is repeated recursively until we reach a terminal node (checkmate or a stalemate) or until the tree reaches a particular depth, at which point it evaluates the board state and uses this value to select its next move.

Current Objectives (in no particular order):

• En passant is currently unavailable for pawns as a legal move.
• Include command line options like the following
  • "--depth [num]" to set a specific depth search
  • "--time" to display execution time for best move search
• Allow the player to undo moves.
• Allow a 2-player game
