The opening featured in many of the games of both Euwe-Alekhine World Championship Matches of 1935 and 1937. After some years, during which its popularity faded in competition with openings such as the KID , today the opening is again extremely popular. Some Black players have returned to the less double edged classical openings such as the Slav and Queen's Gambit Declined to obtain a more solid and level game.} 3. Nc3 Nf6 4.
