In the previous game black wasted time before castling and found himself in a difficult situation. Of course he could have defended himself, but doing so required more precise play than was practically possible.
In the following we see that it's just as dangerous to waste time after castling as it is before castling. Soviet GM Andre Lilienthal (May 5, 1911 - May 9, 2010, 99 years old) vividly proved the point in when he delivered a quick defeat that was made possible simply because he had more pieces in play than his opponent, GM Miguel Najdorf (April 15, 1910 - July 4, 1997, 87 years old). Lilienthal's accumulation of pieces allowed him to simply crush his opponent.

Nimzo-Indian: Saemisch Variation 1.d4 f6 2.c4 e6 3.c3 b4 4.a3
Lilienthal adopts the most forthright way of meeting the Nimzo-Indian by
putting an immediate end to the pin at once. The price is doubled c-Pawns. His
next goal is to play e2-e4. xc3+ 5.bxc3 c5 6.e3 c6 7.d3 b6 8.e2 0-0 9.e4 e8 Black's intention here is twofold. 1) he wants to prevent the N from
being pinned by Bg5 and 2) he wants to make a timely strike at the center with
...f5. It's a good plan, but it requires careful execution. 9...d6 10.g5 h6 11.h4 e5 is an alternative. 10.0-0 10.f4 f5 11.g3 g6 12.e3 d6 13.0-0 a5 14.d5 g7 15.c2 Draw agreed. Miron,L (2498)-Berescu,A (2456)
Calimanesti-Caciulata ROU 2014 10...d6 10...a6 attacking the c-Pawn is
solid, but it does not produce much of anything after 11.a4 11.c2 a5 12.dxc5 12.e3 xc4 13.dxc5 bxc5 14.xc5 d6 15.b4 xd3 16.xd3 c7
Black's weak d-Pawn offsets white's weak c-Pawn. 12...bxc5 13.e3 c8 14.e5 h6 15.g3 unclear. 11...a5 12.dxc5 bxc5 13.b1 with equal chances. 10...b7 11.f4 f5 12.exf5 exf5 13.dxc5 bxc5 with equal chances.
Kuljasevic,D (2501)-Perunovic,M (2589) Kavala 2008 11.e5 11.f4 is
interesting. f5 12.g3 g6 13.f3 with equal chances. Metge,J (2170)
-Sutherland,J (2085) Auckland 1997 11...dxe5 12.dxe5 b7 12...xe5 loses because the N on e8 has interrupted the communication between
black's Q and R on f8. 13.xh7+ xh7 14.xd8 13.f4 The position is
equal. f5 This may look suspect, but it's actually black's best move. 14.exf6 How should black recapture? e5 Najdorf is playing with fire. 14...xf6 This is OK. 15.c2 e5 16.g5 h6 with equal play. 14...xf6
This is OK, too. 15.c2 e5 16.xh7+ h8 17.c1 d6 with equal play. 14...gxf6 This is not OK. 15.e1 g7 16.g3 f5 Necessary to cut off the
line of the B. 17.d2 f6 18.g5 f7 19.ad1 White's position is superior.
15.fxg7 The King's defenses are stripped away. xf4 16.xf4 exf4 17.xh7+ This unforeseen sacrifice wrecks black's defenses. Najdorf
ends up with three pieces for a R, but it costs him him the game. White has a
significant advantage, but with extremely careful play black can put up a
stiff defense. In practical play the task was too daunting even for the mighty
Najdorf! 17.f3 Perhaps Najdorf was expecting a move like this. If so,
then after f6 18.xf4 xd3 19.xf6 g6 20.xg6 hxg6 the unbalanced
material situation is quite unclear. In Shootouts white scored +3 -0 =2 17...xh7 18.h5+ xg7 19.ad1 White needs to bring a R into play and
this is the right one. Playing Rfd1 allows black to equalize! 19.fd1 e7 20.g4+ f8 21.d7 f6 22.xb7 e5 23.h5 d6 and white can make no
headway...5 Shootouts ended in draws. 19...f6 19...e7 20.fe1 This
move shows why the other R was the right one. f7 21.g4+ f8 22.d7 20.d7+ The R on the 7th decides the game/ f8 21.xb7 d8 22.d7 f7 23.d5 Nice! But not 23.Re1 at once. This grandmasterly move, centralizing the Q,
was not flashy, but it's vital in order to keep the attack going. 23.e1
Obviously white needs his remaining piece in play, but this allows black to
play on. ed6 24.f3 e8 and black has practically equalized. 23...b8 23...c8 is a wee bit tougher. 24.e1 c7 25.d1 d8 26.h3 A safety
measure. xd7 27.xd7 d8 28.g4 g5 and white has the win, but he will
have to work for it. 24.e1 24.xa7 is too greedy. After e5 25.d1 c6 26.d7 e5 White is clearly better, but black is annoying him. 24...f3 25.e3 Black resigned 25.e3 g6 25...d8 26.xd8 xd8 27.xf3 xd5 28.cxd5 The ending is lost for black. 26.xf7+ xf7 27.xf3 27.xf7+ xf7 28.xf3+ is a very difficult ending to play and in fact, in Shootouts (which
resulted in 80+ move long games) white only scored =0 -3 =2!! 27...xf3 28.xf3+ is an obvious win. 1–0
