His chess career ended soon after he returned home following a four year stay London. The damp climate took its toll on him, and he often played in a fever, with an infected throat and cold.
Mir Sultan Khan was probably a waiter in the service of the mighty landlord Malik Umar Hayat Tiwana.
Sultan's son retired as an Inspector General of Police and lives in Islamabad. His granddaughter is doing her PhD in Economics at Cambridge. He kept his children away from chess because he told them the game would not bring them bread and butter.
