Teams from China won both the Open section and the Women’s section of the 43rd Chess Olympiad, which took place in Batumi, Georgia. From September 23 through October 5, 1,667 chess players competed, representing 185 teams from 180 countries in the Open section and 151 teams from 146 nations in the Women’s section. Grandmaster Ding Liren was first board for China’s Open section team. This article features a tactic, overloading, from his win over Grandmaster Jan-Krzysztof Duda of Poland.

As I wrote in my book Prepare With Chess Strategy, “Overloading is a chess tactic in which a defensive piece is given an additional defensive assignment which it cannot complete without abandoning its original defensive assignment.” I was quoting Joseph L.
