Black's QBP to QB4(c5) challenged White's QP.
White's usual KKtPawn to KKt3(g3) signals a KB fianchetto plan - not always desirable against the Nimzo as his QBP will lack bishop support. W-Alt.

When castling always touch the king first
Under FIDE laws of chess, if a player deliberately touches a rook and then his king, he is not allowed to castle on that side on that move but must still move the rook if legally possible.
