GENEVA (AP) — A top global chess official Friday called for more research into whether factors such as hormone levels and physical endurance might have an impact on players' abilities at the male-dominated game. Her comments came after the world chess federation was heavily criticized for its decision to block transgender women from official women's events.

The Switzerland-based federation FIDE said the decision, set to take place Monday, would stay in effect until the federation does an assessment of the issue.
