The Boston Chess Congress, held this Jan. 11-13 at the Hyatt Harborside Hotel, was a successful affair. There were 170 entrants and what were reported to be excellent hotel amenities. The clear victor at the tournament was Chao Li, one of China’s leading players. He dispatched three top New England players and drew with Alexander Ivanov in the last round to win by a full point. Here is his fine win with the White pieces against Jonathan Yedidia.
