Chess has become part of rehabilitation programmes in Kenyan prisons, where a growing number of inmates play to learn patience, anger control and better decision-making. Officials at Maranjau Prison say most of their inmates are petty offenders jailed for offences such as assault, and the game is meant to help them live peacefully with family and community; one inmate, 28-year-old Brian Gatonye, says it has made him less impulsive. The programmes are backed by NGOs such as Gift of Chess (a nonprofit that supplies chess sets), the government and the international chess federation, and supporters hope the game can reduce reoffending after release.
