- Proper black/white ownership by respective player.
|

- Proper turn by turn handling;
|
||||
- Proper piece replacement (ie: if piece A eats piece B, piece B is properly replaced without getting a stack under the cursor);
|
||||
- If a pawn reaches row A or row H -> becomes a queen;
|
||||
- If one of kings is defeat -> the game stops;
|

- Actions recording;

- Counter per player.
