MODERN BISHOP'S OPG - Two Kts. Def.
(The) Side Variation

White pushed his QP out a single square after his KB, to defend his KP against 4..KtxP.
Black is unwise to set a "copy" Pawn on Q3(d6) despite freeing his QB. He will lose a tempo without compensation, to White's advantage. B-Alt.
	White	Black
 1.	P-K4	P-K4
 2.	Kt-KB3	Kt-QB3
 3.	B-B4	Kt-B3
