The game started with some dull position where white had no real advantage. Dubov hesitated to play endgame, whoever there was no other way and he continued playing in his style: no direct threats, but manoeuvring and trying to help his opponent lose concentration.

The Queen's Gambit is a chess opening that starts with the moves:

1. d4 d5
2. c4

The Queen's Gambit is one of the oldest known chess openings. It was mentioned in the Göttingen manuscript of 1490 and was later analysed by masters such as Gioachino Greco in the 17th century. In the 18th century, it was recommended by Phillip Stamma and is sometimes known as the Aleppo Gambit in his honour.[1] During the early period of modern chess, queen pawn openings were not in fashion and the Queen's Gambit did not become common until the 1873 tournament in Vienna.

As Wilhelm Steinitz and Siegbert Tarrasch developed chess theory and increased the appreciation of positional play, the Queen's Gambit grew more popular, reaching its zenith in the 1920s and 1930s, and was played in all but two of 34 games in the 1927 World Championship match between José Raúl Capablanca and Alexander Alekhine.

After the resumption of international chess activity following World War II, it was less frequently seen, as many Black players moved away from symmetrical openings, tending to use Indian Defences to combat queen pawn openings.
