Schachadma (2013)

Schachadma (from "schach", meaning chess, and "adma", short for admiral) by Klaus W. Schomberg is a chess family game played on a 12x12 board, inspired by chess and battleships. Each piece is a ship, with between one and four masts. Each turn, a player moves or rotates a ship, after which all of that ship's cannons fire. Enemy masts within range of the cannons are captured; when a ship has no masts left, it is also captured. The tallest mast on the largest ship represents the admiral; capturing an opponent's admiral wins the game.
