Alekhine — Zubarev

Moscow, 1915

• Alexander Alekhine (1892–1946)The fourth World Champion (1927–1935, 1937–1946) and the only one to die holding the title. He won it from Capablanca in 1927, and Alekhine's Defence bears his name.
• Nikolai Zubarev (1894–1951)Soviet master and two-time Moscow champion (1927, 1930). He played in the 1925 and 1933 USSR Championships and later became one of the country's leading arbiters.

Even though Black has two central pawns, White can still push through an advance in the center: the c- and f-pawns help. It also matters that White's four pawns take almost the whole fifth rank away from Black's pieces, so White can prepare the offensive without interference.
