## Overview
### Pieces
ChessPieces extend from `com.ben.chess.pieces.ChessPiece` and should mostly concern themselves with overriding the `canMove` function.
#### Behaviors
Besides the Knight and Pawn, the other pieces in Chess share a lot in common. For example, a Queen is a mix of a Bishop and Rook. A King is just a Queen that can only move in a radius of 1.
Behaviors are reusable bits of logic that make overriding `canMove` simpler. For example, you can use `RookBehavior` to allow a piece to move in straight lights. Another common behavior is `UnobstructedBehavior`, which stops a piece from passing through other pieces.
As a bonus, behavior tests can be "stacked" too, which means you can assert that a Queen behaves like a Rook and Bishop instead of copying bits and pieces of both test suites over.
### Boards
ChessBoards extend from `com.ben.chess.boards.ChessBoard` and are two dimensional arrays of `ChessBoardCell`. They should override `getBoard` to define the playing field.
### Games
Games extend from `com.ben.chess.games.ChessGame`, which implements a game loop and rules common to most chess variants. The `move` method should be overridden to modify game logic.
## Tests
You can diff the GUI output with the reference images in `tests`
Start a chess game.
* White should be on top
* There should be a row of pawns on each side
* There should be a rook on each corner
* Next to the rooks should be a knight
* Next to each knight should be a bishop
* Between the bishops should be a Queen and a King
Move white's fourth leftmost pawn down one cell
Move black's third leftmost pawn up one cell
Move white's queen to check black's king
* There should be a red stroke around black's king
* Moving any piece other than the second leftmost pawn should be an invalid move
* Moving the second leftmost pawn up one cell should end the check and clear the red stroke
Click surrender
* Black should be given the option to accept a tie
* If yes, the score should remain the same
* If no, black should have one point, while white has zero
