The June 2017 issue of Chess lists the top twenty openings compiled from a list of 2105 April games where both players were rated over 2400 Elo. One can not take position on this list too seriously because it is greatly influenced by how the openings are grouped. For example, all the Retis are grouped together, while English is separated into 1...c5, 1...e5, etc. Nevertheless, for what it is worth, some of the list entries are: 145 Retis, 102 Caro-Kanns, 92 King's Indians, 90 Nimzo-Indians, 88 declined Queen's Gambits, 86 1 d4 Nf6 sidelines, 85 Slavs, 56 Najdorf Sicilians, 55 1...Nf6 Englishes, 53 1...c5 Englishes, 48 2 Nf3 d6 sideline Sicilians, 45 Semi-Slavs, 42 1 d4 d5 sidelines, 41 Catalans, 40 1...e6 Englishes, 40 1...e5 Englishes, 38 Classical Gruenfelds, 36 Berlin Ruy Lopezes, 35 Taimanov Sicilians, and 33 Dutches. (If previous lists are any indication, the French may have been kept out of the top twenty because of being separated into different variations.)
