I used to not appreciate this kind of play for training purposes and would grumble to myself that the computer should stay in book, otherwise it wasn't a real test of the opening. However, I now better appreciate these kinds of moves, since they do replicate what can occur with unprepared opponents, while the moves themselves are not immediately refutable. Sometimes they can even be rather tricky to deal with, introducing unfamiliar tactical possibilities at an early stage. Because an important part of a player's opening preparation consists in being able to take advantage of opponents' missteps, I find this type of experience valuable, especially because of its out-of-book nature.
Black's time-wasting play allows White to build up an advantage, although White's alternatives to the actual game, found in analysis, are instructive in how to better exploit Black's weaknesses. Essentially, White should have accelerated the queenside play or more directly challenged Black's moves. Black eventually drops the b7-pawn, but White's follow-up play was not optimal and on move 24 Black starts generating some threats of his own. White had some fantastical thoughts of penetrating on the kingside with queen and knight, but Black easily disposed of this possibility. My thinking process deteriorated and in the next sequence of moves the advantage disappeared and Black could have achieved a winning game, but instead gifted White a won N+P endgame.
Some specific points to take away from this game, both related to the KID setup against the English and in more general terms:
- Do not dismiss the possibility of playing d4 if it leads to an advantage (move 8)
- It is better to get in Rb1 and the b4 push early (move 9)
- Look to activate the queen on the queenside to generate additional threats (move 18)
- Do not underestimate the strength of a centralized black knight; in this game, it tied me to the defense of e2, while in Annotated Game #15 a similar situation occurred with an attack on e3. Exchange the knight off soonest or consider a prophylactic move to take away its central outpost.
- Concrete calculation rather than limited intuition is necessary to the planning process. I began seriously drifting as of move 26 (just after the missed threat from Black to e2, which however was easily dealt with) and did not calculate properly.
- I must reduce the psychological impact of unexpected moves; proactively I need to better examine my opponent's possible candidate moves for threats

[8.d4
would take advantage of the blocking of Black's Bg7 8...cxd4
9.Nxd4
Nxd4
10.Qxd4
and Black has no useful discovered attack moves with the Nf6, while White has a lead in development.]
8...Ng4
+0.52
another time-wasting move. 9.Qc1
+0.37
this does not seem to be the most effective plan (idea is to exchange off the Bg7).
[9.h3
Nf6
10.Ng5
would take direct advantage of being able to kick the Ng4; a subsequent ..h6 would give White a target on the c1-h6 diagonal.;
Simply getting on with queenside expansion by 9.Rb1
O-O
10.b4
also looks superior.]
9...h6
+0.72
Black seems to be deliberately not castling.
[9...O-O
10.Rb1

11.h3

11.b4

19.Bg2
O-O
finally! 20.Nd5
Here I began playing largely by rote, simply looking to exchange down pieces, rather than looking to exploit the queenside advantages, although this should still work out fine for White.
[20.Nb3
threatens to exchange off the Nc5, a strong blockading piece for Black. 20...Na4
21.Bd2

Be6
23.Bxe6

24.Bd2

I missed this threat to e2, which reflects a similar-looking threat by a centralized knight that also appared in another recent game, so this is definitely a tactical theme to watch. 25.Re1
h5
26.Bh6
[26.Be3
is preferred by Rybka, with the idea of exchanging off the Nd4. Black's Bg7 is not an effective piece, so getting rid of the dominating knight is worth White's dark-square bishop.]
26...f5
this counterblow puts an end to any White fantasies about a kingside attack. 27.Bxg7
Kxg7
28.Nc3
Qc6
29.Nd5
[29.Nb5
is more effective and forces the exchange of the Nd4. 29...Nxb5
30.cxb5
Qb6
]
29...Rb7
At this point my thinking process started deteriorating. The clock wasn't running too low, so it was largely self-inflicted. 30.Rxb7+
Qxb7
31.Qb1?!
+0.72
this starts a downward slide where White throws away most of his advantage. Kf1 to protect e2 looked dubious due to the Qb7-h1 threat, effectively pinning my Nd5. I did not see that
[31.Qd1!?
Qb2
32.e3
Nc6
33.Re2
would have saved White's advantage.]
