Starting position. The white figure is a maharajah; it can move as queen or knight.

Game rulesEdit

Black has a full, standard chess army ("sepoys") in the usual position. White is limited to a single piece, the maharajah, which can move as either a queen or as a knight on White's turn (hence a manifestation of the amazon). Black's goal is to checkmate the maharajah, while White's is to checkmate Black's king. There is no pawn promotion.[2]

The asymmetry of the game pits movement flexibility and agility against greater force in numbers. By perfect play, Black always wins in this game, at least on an 8×8 board. According to Hans Bodlaender, "A carefully playing black player should be able to win. However, this is not always easy, and in many cases, when the white 'Maharaja' breaks through the lines of black, he has good chances to win."[3]

Winning strategyEdit

The maharajah can pose a serious threat and even win against a weak opponent. Its strategy is to clean as many black pieces as possible in the early game using forks (attacking more than one unprotected piece at once) as the main tactic; after sufficiently cleaning the board, by giving checks, chase the black king away from its other pieces, drive it to an edge of the board and give checkmate.

Maharajah's critical weakness is that it is royal, so it cannot do exchanges, meaning it cannot capture black pieces that are protected. So the Sepoys' winning tactic is to make moves in such a way that all their pieces stay protected while gradually taking away available squares from the maharajah. It is also important to make sure the maharajah cannot give checks.[citation needed]

Final position after 24...R3b2#

One example line of moves that gives Black a forced mate in 24 moves goes like the following (White's moves are unimportant as, in this variation, White cannot legally capture any piece or be stalemated):[4]

1... d5 2... Nc6 3... Qd6 4... e5 5... Nf6 6... a5 7... Ra6 8... Rb6 9... Bg4 10... e4 11... Qe5 12... Be7 13... 0-0 14... Rb2 15... Ra8 16... Ra6 17... Rab6 18... R6b3 19... h5 20... g5 21... Nh7 22... Qd4

Now, if the maharajah is on a1, then:

23... Rb1 24... R3b2# (diagram) 0–1

Else:

23... Qd1# 0–1
