St Louis (US):Indian Grandmaster R Praggnanandhaa moved a step closer to qualifying for the Grand Chess Tour Finals after finishing at the top of the rapid standings at the St. Louis Rapid & Blitz tournament. Unlike the rapid format, where each victory is worth two points, blitz wins carry one point each, leaving the title race wide open despite Praggnanandhaa's lead. Among them, Keymer is considered particularly dangerous in blitz chess and could emerge as a serious contender with a strong run of results. A high finish in St. Louis would considerably improve his prospects of securing a place in the Grand Chess Tour Finals later this year. Following the conclusion of the rapid and blitz event, the players will remain in St. Louis for the Sinquefield Cup, the final classical tournament of this year's Grand Chess Tour calendar.
