Tamerlane chess is a medieval chess variant. Like modern chess, it is derived from shatranj. It was developed in Central Asia during the reign of Emperor Timur, and its invention is also attributed to him.[1] Because Tamerlane chess is a larger variant of chaturanga, it is also called Shatranj Al-Kabir (Large chess or Great chess), as opposed to Shatranj as-saghir ("Small Chess"). Although the game is similar to modern chess,[2] it is distinctive in that there are varieties of pawn, each of which promotes in its own way.[3]
