The Mujannah Opening

Black's QPawn challenged White's QBP directly.
White advances a gambit KBPawn to KB4(f4), leaving his QBP to tempt Black's QP aside - the rare Mujannah System. Openings expert Hugh Myers (1930-) defined it as going on to add Q4+K4(d4+e4) pawns "no matter how long it takes". W-Alt.
