The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.

It begins with 5 plies and takes 1. e4 d6 2. d4 Nf6 3. f3 to reach the canonical position.

It is a variation of Pirc Defense, which itself descends from the root opening King's Pawn Game.
