Straits 1892

Straits is a Chess-like game for two, played on a 9 x 11 hourglass-shaped grid of checkered squares. Each player has nineteen pieces of his own color: one Flag-ship, 7 Turret-ships, 8 Torpedo boats, and 3 Gun-boats. Their rules of movement are as follows:

)Flag-ship - it moves and captures like a Queen in Chess, but it cannot be captured and must not move into check or remain in check. )Turret-ship - it moves and captures like a Rook in Chess. )Torpedo boat - it moves and captures like a Bishop in Chess, and is consequently bound to squares of the same color. )Gun-boat - it moves one square in any direction, but can capture only diagonally.

The first player to move his Flag-ship to the board's central square or who checkmates the Flag-ship of his opponent wins the game.
