The basic ingredients of the Nievergelt Manoeuvres are already familiar, for instance from Stonewall-like structures.
In that case, however, ...g7-g5 immediately hits the doubled pawn on f4 and threatens to open the g-file. With the true Nievergelt Manoeuvre, you may hope to just create a half-open file in the long run. To refresh your memory - repetition is an important pillar of learning.

You won't have any problems at least considering the possibility of this move any more, I hope.

You see the difference. There's immediate concrete tension: Black threatens to take on f4.

White allows the f-flle to be opened without undoubting his f-pawns.

If White got in e4-e5 and f4-f5 he'd be in great shape. Now, however, it's Black who has the chance to sacrifice the exchange.

Black has more than enough compensation for the exchange.

Majestic Maneuver

Taking your king for a walk in the heat of a complex middlegame - in some positions it is the logical thing to do, in other cases it may be a quite surprising action.

Let's just hear what Lilienthal had to say about his decision: 'Black has to bring his rook from h8 into the game. But castling is dangerous: White is all geared up for an attack on the kingside. Because of this, I decided to send my king in the other direction.'
Sounds sensible enough, does it not? Besides, you can observe that the position is closed and as a result, the king will be safe on c7. When Black opens up the b-file with . . . b5 -b4, the king will even be able to assist here, controlling some important entry squares.

Anticipating . . . b5 -b4.
