DUTCH DEFENCE
(to) Stonewall / Ilyin-Genevsky Vars.

White's KKtP started an "Indian" KB - well-placed in this opening, as he does not yet control his K4(e4).
Black's King's Pawn to K3(e6) deters 4.P-Q5 and frees his KB for a potential ..B-QKt5 against the QKt which White might soon develop (to support a P-K4 attempt). The "Alt" route until 1960s ECO coding. B-Alt.
     White   Black
 1.  P-Q4    P-KB4
 2.  P-QB4   Kt-KB3
