The Sicilian Defense: Bowdler Attack arises after 1.e4 c5 2.Bc4 and falls under ECO code B20. This is a mistake that allows clear equality. Black's best answer is 2. ...e6 followed by d5 at some point which easily removes White's bishop and gives Black a tempo and clear centre. For example: e6 3. Nc3 Nc6 4. Nf3 Nf6 5. O-O d5 6. exd5 exd5 7.Bb3 Black needs to play Nc6 before d5, otherwise the king will be exposed on the a4-e8 diagonal, and therefore inviting a check from White's light square bishop. It is analogous to some lines in the Italian Game but Black has played the move c5 which helps prevent d4 and makes b3 a less attractive place for the White Bishop (because of c4).
