About this opening
The Mujannah Formation (1.d4 c5 2.d5 f5) pairs the Benoni's c5 pawn with a Dutch-inspired ...f5 push. Black aims for space and control of e4 on the kingside, in an original, combative structure. The weakening of the a2-g8 diagonal and the e6 square is the flip side of this ambition. It is a rare line, for fans of asymmetrical, unbalanced positions.
