TRANSPOSITION
ORTHO-QGD. to NIMZO-INDIAN DEF. (Steiner V.)

Black's king's bishop to QKt5(b4) pinned White's QKt to deter 4.P-K4, usually planning 4..Kt-B3 for a Nimzo-Indian but giving White several options.
White posts his KKtPawn on KKt3(g3) planning a KB fianchetto to contest the light centre. W-Alt.
