A regional chess played in 19th-century southern India, recorded in H.J.R. Murray's "A History of Chess." It appears to descend from a form of chess brought by European traders in the early 17th century. There is no rook; instead, the King and Vizier (Ferz) sit at the center, flanked on each side by a Camel, then a Horse, then an Elephant. Sources note the 1st, 4th, 5th, and 8th ranks and files as specially marked squares, though their exact effect isn't clearly documented.
Simplification: the marked squares are shown only as a visual reference and have no functional effect here. A pawn historically promoted to "the rank of any piece already lost" upon reaching the opposing king's square; this is simplified to promoting to a Vizier (Ferz) upon reaching the last rank. Check and checkmate aren't enforced — capturing the king directly ends the game.
