The Williams Variation

White's KKt contested for control of the two dark centre squares by countering Black's QKt influence.
Black here posts his Queen's Pawn on Q3(d6) and frees his QB for a likely 3..B-KKt5 pin, rather than play 2..P-Q4 towards a Centre Counter Game or 2..P-K4 (best) to rejoin the "Dorsal Fin". B-Alt.
     White   Black
 1.  P-K4    Kt-QB3
 2.  Kt-KB3  P-Q3  Transp.from Wade D.
