Milestone 2: Move Validation

[haxybaxy]

Objective

Implement move validation to ensure that only legal moves are allowed.

Steps

1. Define a method to validate moves for each piece type.
2. Implement logic to check for check and checkmate conditions.
3. Ensure that the move validation logic is integrated with the board representation.

Example Code:

def validate_pawn_move(start, end, color):
    dx = end[0] - start[0]
    dy = end[1] - start[1]
    if color == 'white':
        return (dx == -1 and dy == 0) or (start[0] == 6 and dx == -2 and dy == 0)
    # Add black pawn logic
