Mujannah

The Bird Opening: Mujannah arises after 1. f4 Nf6 2. c4, with White pairing the f-pawn with an early c-pawn advance. The result is an English-style setup that bears on d5 and e5 from the flanks rather than occupying the center. It is an uncommon choice. The most frequent reply is 2...g6, ahead of 2...e6 and 2...d5, the last of which challenges the center at once and has scored well for Black. The engine rates the position as roughly balanced, though Black wins more often on Lichess.
