If after 1.e4 Black does not play 1...e5, then we have the Semi-open Openings. These include the Sicilian (1...c5) which is probably the most popular opening of all nowadays. But there is also a large fan-base for the French (1...e6) and the Caro-Kann (1...c6). In addition, this group of openings also contains some very modern systems such as the Alekhine Defence (1...Nf6), the Scandinavian Defence (1...d5) and the Pirc Defence (1...d6 or 1...g6).
