Modern Chess, Opening Databases, 2020.
The English Opening has always been one of White's most fundamental choices. You will hardly find a top-level player who does not have this opening in his repertoire. Nowadays, in our computer-driven era, English Opening is getting even more popular. The reason is that it is by no means simple for the opponent to prepare against 1.c4. Since the pawn structure is very flexible, we have a wide range of options on every move. Therefore, in most of the lines, general understanding tends to be more important than knowledge of concrete lines. One of the most critical responses to 1.c4 is 1...e5. Black immediately grabs space in the centre and obtains a Sicilian position with colours reversed. In this database, GM Roiz starts building a complete repertoire against 1...e5. His repertoire is based on 1.c4 e5 2.g3.
