A wrong combination.

4... Qe7!
A typical maneuver in the Carlsbad structure. Black intends to transfer his knight to the ideal d6-square, in order to control the e4 and c4 squares and prepare ...Bf5 as well.

White should hurry to exchange off pawns to hold the game.
46.h4! Rxf2 47. h5 Ne4 48. hxg6 hxg6 would have put up more stubborn.

27...Bc8!
All of Black's attacking moves in this game have a very modest appearance. Black creates a threat to the h2-pawn after 28...Bb7.
Worse was 27...Rxb2 28.Bb3 and 29.Na4.
28.Rcd1 f5!
The move 28...f5! makes use of the rook on h6 for defense as well as attack. It also has the added benefit that Black's dark-squared bishop comes to life.
29.Rhe1
Still trying to fight for the initiative.
29...Bd7!
After this move, which simultaneously attacks and defends, White's position suddenly falls to pieces.

19.Bc1!
A strong retreat.
19...Nd7 20.Re1
A prophylactic move against ...f7-f6.
In the case of 20.a4, the move 20...f6 would be a reasonable continuation because it would release the pressure on the kingside and activate Black's pieces.
20...Rac8 21.a4 Qd8
Black is still dreaming about creating pressure on White's pawns with ...Qc7.
More reasonable was 21...Nc5 22.Nd4 Na5! and Black can defend.
22.Nd4 Nc5 23.Qg3
