CENTRE PAWN (aka. Lopez) OPENING
(The) Side Variation
White set his QBPawn on QB3(c3) to support 3.P-Q4, adopting an irregular (ie. rarely played) opening.
Black's poor early Queen's Bishop development will not deter a White 3.P-Q4 to control the centre, as 3.P-Q4..PxP, 4.PxP..BxP?!, 5.QxB will give White clear advantage over Black's king's-side. B-Alt.
	White	Black
 1.	P-K4	P-K4
 2.	P-QB3	B-B4?!
Example ends: Undo or Jump or Clear
