(The) Side Variation

White's QP attacked Black's KP and stymied ..B-B4.
Black makes a bad move advancing a KBPawn gambit to KB4(f5) hoping to drag White's KP off-centre (correct move being 3..PxP). White will win a pawn after 4.PxBP..PxQP, 5.KtxP..KtxP, 6.QxP with good command of the centre. B-Alt.
     White   Black
 1.  P-K4    P-K4

 3.  P-Q4    P-B4??
