Marshall Gambit - The Portuguese Variation

White advanced his rear QPawn to Q4(d4) rather than try to keep his doubled Q5(d5)P.
Black ignores 3..KtxP and develops his Queen's Bishop to KKt5(g4) deliberately to confuse matters! Line continues 4.P-KB3..B-B4, 5.P-QB4..P-K3. B-Alt.
	White	Black
 1.	P-K4	P-Q4
 2.	PxP	Kt-KB3
 3.	P-Q4	B-Kt5!
