Today I finished pawn move validation in my ChessGame class!

validate_pawn_move(self, move: ChessMove) -> bool – A function that takes in a ChessMove object and analyzes the validity of a pawn move.

• The goal is to have a move validation function for each piece type so I can just use simple case branching logic to validate moves
• After validating that the move can actually happen on the board, I plan to create a deep copy of the board with the movement to ensure we don't move into check
• Following a successful validation, I'll replace self.board with the updated board based on the move

This is a great step in the right direction towards validating moves. Once I can successfully validate that moves work, I can actually have 2-player functionality.

Next Steps:

---

• I need to finish a validate_xxxxx_move() function for each piece
• There also has to be a function that takes in the new board and validates that the player doesn't move into check
• Down the line, I think I can simplify user input to not require super strict chess notation. A natural language chess game could be really neat.
