The Asian Continental Chess Championship is heading for a close finish as four players are now sharing the lead with just two rounds remaining.
The seventh round on Tuesday produced some exciting matches and unexpected results. On the top board, leader Harsha Bharathakoti signed the peace treaty with second seed SL Narayanan while top-seeded Grandmaster R. Praggnanandhaa won a marathon 137-move game against compatriot Karthikeyan Murali to move into joint lead with three others on five-and-a-half points.
International Master Koustav Chatterjee upset two-time national champion Aravindh Chithambaram to join Praggnanandhaa, Bharathakoti and Shamsiddin Vokhidov of Uzbekistan at the top. Member of the Olympiad gold medal-winning Uzbekistan team, Vokhidov joined the leaders' pack after defeating former Asian champion SP Sethuraman.
