With hints on, the player's pits show whether their move gives an extra turn
or how many stones it takes, and a line under the board says what the last
move did and why. A Hints switch appears only in games against the bot.
RULES defines every rule with an example and a lesson; getMoveOutcome works
out a move's effect with the engine, explainMove says what happened, and
describeMove now tells the kind of capture and how many stones it took.
