Black developed his KB to K2(e7) to deter a potential B-KKt5 pin, and to enable rapid castling.
White advances his delayed QBPawn to QB4(c4) to control Q5(d5) now that Black has posted his KB, and usually plans Kt-QB3 behind the QBP. 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.
