Despite the immense difficulty of this task, we did our best to bring you this website, so that you may enjoy playing the game of Go with your friends. After Google's AlphaGo's victory against the best human Go player, there's not really a point to playing against a computer - you will lose.

-                        Matt adapted the Crystal back-end to work with SQLite. This meant loading and saving Go games into the database instead of an in-memory cache, thereby allowing games to persist after server restarts.

The black player has 15 points of territory - 10 in the bottom right corner and 5 at the top of the board. They also earn a point for capturing a white dot at location a, so their total is 16 points. The white player has 17 points - 11 along the left side and 6 in the top right corner. Therefore, the white player would win by 1 point.</li>
