Black: I. Nei English Opening 1 c4 c6 2 e4 e5 3 Nf3 Qc7 4 Nc3 Nf6 5 g3 Bb4 6 Bg2 d6 7 0-0 Bg4
8 h3
Three points. Simple, yet forceful, securing the slight advantage of the Bishop pair. An extra point if you had a look at d4 and decided that the absence of any Black counterplay against it made the exchange of the Nj3 less important. 8 d4 would allow Black to grab a pawn and weaken White's pawn skeleton by 8 .. . Bxc3 9 bxc3 Nxe4 but only at the expense of dangerous counterplay based on Black's uncastled King: 10 Qd3 Bxf3 1 1 Bxf3 Nf6 12 dxe5 dxe5 1 3 Ba3 would set Black problems. Two points for 8 d4, but only if you saw the continuation. Two points also for the solid and sound 8 d3. Nothing else scores. Deduct a point for 8 a3, 8 Qb3 or 8 Qa4, which lose the e-pawn after 8 ... Bxc3. 8
Qc2 (no points) allows Black to double the c-pawns.
8 . . . Bxf3
9 Qxf3
Two points. One point for 9 BxD ; nothing else scores.
9 . .. Nbd7
10 a3
Three points. Two points also for 10 Ne2, e.g. 10 . . . d5?! 1 1 cxd5 cxd5 1 2 exd5 and White wins a pawn. One point for 10 Re 1 or 10 Rd 1 though the best square for this Rook is far from obvious as yet. 10 b3 does not score because it is equally unclear which diagonal will best suit White's Bel .
10 ... BcS
1 1 b4
Two points. 1 1 d3 is hardly worth a point here.
1 1 . . . Bd4
12 Rbl
Because this is so strong, three points, and a fourth if, when you chose White's 10th move, you envisaged his 1 1th and 1 2th as well, for they represent far and away the best plan at this juncture. 12 Bb2, intending 1 3 Rae l , though slow, earns a point.
12 . . • Nf8
Three points. Completely thematic. Until the Bishop is exchanged, b4-b5 might only enlarge its scope. 1 3 Bb2 does not quite earn a point, though the idea of following it up with 14 Ne2 Bxb2 1 5 Rxb2 followed by 16 d4 has certain attractions; but in a position that can easily be opened, the text, visualizing two Bishops against two Knights, is obviously White's most promising course. Ergo, nothing for 1 3 Re 1 or 1 3 Rdl .
1 3 ... Ne6
14 Nxd4
Two points for this simple and direct move. No points for 14 h4 intending 1 5 Bh3, which is too committal before Black has castled. 14 d3 is perhaps worth a point even now.
14 ... Nxd4
15 Qd3
Two points. Deduct six points for 1 5 Qc3 when 15 . . . Ne2 wins. Nothing for others.
15 ... c5
16 Bb2
Two points. Deduct two points for 16 bxc5? which after 16 .. . dxc5 leaves the d-file open for exploitation by Black. No other move is directly linked to White's long-term plan.
16 ... a5?
Not a good move. Black had to castle without further delay.
1 7 bxc5 !
Three points. Nothing for 1 7 bxa5 Rxa5 with helpful counter play along the a-file. Deduct a point for 1 7 b5, blocking the Queen's wing.
1 7 ... dxc5
18 Bxd4
Four points. This had to be played at once. Two extra points if you realized that Black loses a pawn after either 1 8 .. . Rd8 or
18 .. . 0-0-0 by 1 9 Bxe5 !
18 ... cxd4
19 f4!
The key to White's strategy. Four points. His idea was to allow Black to set up the outpost on d4, only to undermine it by f2-f4; if a plan like this entered your head on move 14 take three extra points.
19 ... Nd7
20 fxe5
Two points. Nothing for anything else.
20 ... Nxe5
21 Qxd4
One point. Nothing for anything else.
21 ... Rd8
22 Rxb7!
Five points if you saw this magnificent move. 22 Qb2 Qc5ch 23 Kh2 0-0 is not so clear. If 22 Qb6 Qxb6 23 Rxb6 Nxc4 24 Rxb7 0-0 and White cannot hold his extra pawn. One point for 22 Qb2; no credit for anything else.
22 ... Rxd4
22 .. . Qxb7 can hardly be considered in view of 23 Qxe5ch Qe7 24 Qxg7 or 23 .. . Kf8 24 Qxa5
securing'- a third pawn for the exchange and depriving Black of the right to castle.
23 Rxc7
A token one point for this.
23 ... 0-0
At last!
24 Rc5
Three points. Again, how can anything else qualify for credit when this one pure forcing move leaves Black no option but to . . . well, take another point if you have already foreseen Black's reply and White's follow up.
24 ... Nxc4
25 Rel ?
No points! Balashov allows Nei the chance of a draw. Correct was 25 Rd5 ! with positions similar to the game. Black's best continuation would then be 25 . . . Rxd2 (25 .. . Rd8 26 Rel i s worse) 26 Re l Rxg2ch 27 Kxg2 Ne3ch 28
Kf3 Nxd5 29 exd5 Rd8 30 a4 ! followed by 3 1 Rc5 when White either wins the a-pawn or forces the Black rook into a passive position. Take four points for 25 Rd5 and three bonus points if you found the subsequent analysis.
25 . • . Nxd2
26 Rd5
No points. With 26 .. . Rc4 ! Black could now have forced a draw.
26 . . . Rxd5?
27 exd5
Score a gift point!
27 ... f5
28 Rc5
Three points for this with its neat combination of a simple pawn gain by 29 Rxa5 and the fearsome concealed menace of 29 d6 followed by 30 Rd5.
28 ... Rb8
29 d6
Three points. Nothing for 29 Rxa5, for which Black was no doubt hoping; he can reply 29 . . . Rb lch, e.g. 30 Kf2 Rb2 confronting White with trouble some problems. For example, 3 1 d6? Nc4 dis. ch and 32 .. . Nxa5 . Or 3 1 Ke3 ?? Nc4ch. Or 3 1 Ra8ch Kf7 32 Ke3 Nc4ch 33 Kd4 Rxg2 34
Kxc4 Rxg3 is not much better for White, either. 30 Kh2 Rb2 would also be troublesome, e.g. 3 1 h4 Nf3ch 32 Khl Rb lch 33 Bfl Rb2 ! (33 .. . Rxflch 34 Kg2 is more risky for Black) drawing by repetition.
29 • • •
30 d7!
Kf7
Three points. The most forceful continuation. If now 30 . . . Rd8 3 1 Rxf5ch wins easily. 30 Rxf5ch is slowest and only deserves one point.
30 ... Ke7
31 Re5ch
Three points. But only if you saw that 3 l . . .Kd8 loses to 32 Re8ch and 3 l . . .Kf8 fails after 32 Bc6. No points for anything else.
3 1 ... Kxd7 32 Rd5ch One point. 32 • • • Ke7 33 Rxd2 One point. 33 ... Rb3 34 a4
Two points. White does best to preserve the "distant" pawn. Nothing for 34 Kh2 or 34 Rd5; even though they would no doubt allow White to win in the long run, either makes his task more difficult.
34 • . • Rxg3
35 Rd5
Two points. Obtaining a passed a-pawn. The only move to score.
35 • • . f4
36 Kf2
Two points. Deduct four points for 36 Rxa5? (36 .. . j3!).
36 ... g5
37 Rxa5
One point.
37 ... h5
38 h4!
Three points. The most efficient way of terminating the game. 38 . . . g4 is met by 39 Rxh5 Ra3 40 Bc6. Other moves such as 38 Ra8 and 38 Ra6 are slower and score only a point.
38 • . . gxh4
39 Bf3
Three points. Now the Black Rook is cut off from the rear of the a-pawn, e.g. 39 . . . Rh3 40 Rxh5 Rh2ch 41 Bg2. Black resigns.

9 ... b5
Three points. Natural and strong. Black gains space on the queenside and prepares to fianchetto his Bc8. It was important for you to consider 10 a4 - a common reaction to Black 9th move. If you intended 10 . . . b4 1 1 Nd5 Nxd5 1 2 Qxd5 Rb8 followed by . .. 0-0,
. . . Bb l and . .. N/6 take a bonus
point. One point for 9 . . . 0-0 or 9 .. . b6 which allow 10 a4 !
10 h3
10 • • . Bb7
Two points. The logical follow up to Black's last move ' increasing pressure on White's e4 pawn and d5. 10 . . . 0-0 gains only one point, as does 10 . . . b4.
1 1 g4
1 1 ... b4 !
Four points. The most forceful continuation. Moves like 1 1 . . .0-0, l l . . .Rc8 and l 1 . . .Qc7 score no points as they allow White to take the initiative with 12 g5, e.g. 1 1 . . .0-0 12 g5 Ne8 (12 .. . Nh5
13 Bj3!) 1 3 h4. 12 Ng3 would also be strong for White in this variation. But 1 1 . . .Nc5 deserves three points. After 12 Ng3 b4 1 3 Nd5 Nxd5 1 4 exd5 a position akin to the game is reached .
1 2 Nd5
12 ... Nxd5
Three points. Take an extra point if you saw this move when playing l l . . .b4, realizing White's 12th move was forced to protect the e-pawn. 12 . . . Bxd5 was not as
good - Black wants to improve the scope of his black-squared Bishop and prevent g4-g5 - but it still rnerits a point. Other moves such :is 1 2 ... 0-0 allow 1 3 Nxe7ch
followed by pressure against the weakly defended d6 pawn.
13 exd5
13 ... 0-0
This necessary preliminary to any further action by Black gains two points. 13 . . . h5 is too dangerous after 14 Ng3 .
14 c4
14 ... bxc3
A difficult juncture in the game. Black has to decide how to increase his small advantage (pressure on the d5 pawn and the weak black squares on the kingside). The text scores two points as it isolates the d5 pawn. Two points also for a plan which involves moves like ... Nc5, . .. Bg5,
. . . Bc8, and the gradual preparation for . . .j7-f5.
15 Nxc3
15 ... a5
Two points. Controls more area on the queenside and prepares . . . Ba6. 1 5 .. . Bg5 merits one point.
16 Rel
16 ... Nc5
Two points. An extra point if you saw that 1 5 .. . a5, a necessary preparation for this move, prevents 17 b4. 16 . . . Ba6 and 16 . . . Bg5 both score one point. Deduct three points if you chose 16 . . . Rc8 1 7 Be3 Nb6? 18 Qb3 !
1 7 Be3
1 7 ... Rc8
Three points. Necessary to prevent the splitting of Black's pawns after 18 Bxc5. 17 . . . Qc7 with the same object in view would be less accurate. After 1 8 Re l the Black Queen is vulnerable vis-a-vis the Rook.
18 Na4!
18 ... Nxa4
One point. A retreat would be an admission that 16 . . . Nc5 was a waste of time, and to allow 1 9 Nxc5 and the resulting weak pawns is out of the question.
1 9 ... Ra8!
Four points. Balashov's active defense is almost on the point of equalizing, and Black has to play accurately to keep a small edge. Now on 20 Qb5 Ba6 ! 2 1 Qb6 Qxb6 22 Bxb6 Rfb8 23 Bxa5 Rxb2 and Black has the superior ending - better pawn and more active pieces. Moves which underestimate the strength of 20 Qb5 score no points, e.g. 1 9 .. . Bg5? 20 Qb5 Bxe3 (20 .. . Rb8 21 Bal) 2 1 Rxe3 and White is better. On the immediate 1 9 .. . Ba6, 20 Bd2 ! causes diffi culties for Black.
20 Rael
20 ... f5!
Three points. The time has come to attack White's kingside weaknesses. Other moves are too slow in the face of White's queenside pressure.
21 Qb5
21 ... Ba6
One point only. A broad hint has already been given about the strength of this move.
22 Qc6
22 ... fxg4
Two points. 22 .. . f4 allows 23 Bb6. Now 23 Bb6 is met by 23 .. . Qb8 24 hxg4 Bg5 ! 25 Be3 (25 R c2 Rc8!) 25 . . . Bxe3 26 fxe3 Qxb2 27 Rc2 (27 Qxd6 Qflch 28 Khl or 28 Kh2 R/6) 27 . . . Qb4 ! Two bonus points if you saw these variations.
23 hxg4
23 ... Bh4
Two points. Aiming at j2. 23 .. . Bg5 loses a pawn after 24 Bxg5 Qxg5 25 Qxd6.
24 Be4
24 ... Qf6
Two points. This would also have been the answer to 24 Bb6. No other moves deserve to score.
25 Qc2
25 ... g6
One point. Black nullifies the threat against h 7 and prevents Bf5. No points for 25 . . . Rac8. After 26 Qd2 it is difficult to see how Black can make progress.
26 Kg2
26 • . . Rab8 !
Three points, but only if you saw that 27 a3 fails against 27 .. . a4 intending 28 . . . Rb3 (28 Qxa4 Bxj2 wins).
27 Rhl
27 ... Rb4
Two points. An extra point if you saw that 28 a3 brings White into difficulties after 28 .. . Rc4 29 Qbl Rxc l 30 Qxc l Bxf2 !
28 ... Bg5
Three points. Planning to eliminate White's black-squared Bishop. 28 . . . Rc4 is less strong now: 29 Qb l Rxc l 30 Qxcl Be2? 3 1 g5 ! or 30 . . . Bxf2 3 1 Bg5 ! Qf7 32
Rf3 . The game now reaches a critical point.
29 b3
29 ... Bxe3
One point. The logical continuation after Black's last move. White threatens 30 a3 .
30 Rxe3
30 ... Rxe4 !
Five points. Take two extra points of you visualized this when playing 28 . . . Bg5. White could not of course play 30 fxe3 because of 30 .. . Rxe4 ! 3 1 Qxe4 Bflch 32 Rxfl
Qxflch 3 3 Kh2 (33 Kg3 Qf2 mate) 3 3 .. . Qe2ch! and wins. A further point if you saw that 3 1 Qxe4 lost to 3 1 . . .Qxf2ch 32 Khl Rf4.
31 Rxe4
31 ... Bd3 ! !
This beautiful move i s the point of the whole combination.
Six points if you spotted it. Only one point for 3 1 . . .QDch?! 32 Kg l Bd3 3 3 Re3 ! Qxg4ch 34 Rg3 Qxg3ch 35 fxg3 Bxc2 36 Rxc2 Rf3
37 Rc8ch! and 38 Ra8 gives good drawing chances for White.
32 Qxd3
32 ... Qxf2ch
One point. The only move to consider.
33 Khl
33 ... RO
One point. Again there is little alternative. Take a bonus point if you saw that 34 Re2 Qh4ch 35 Rh2 Qxh2ch 36 Kxh2 Rxd3 followed by .. . Rxd5 wins easily.
34 Rc8ch
34 ... Kg7
One point; the same for 34 .. . Kf7.
35 Rc7ch
35 ... Kf6
Two points. Deduct three points for 3 5 ... Kf8 36 Rc8ch Ke7?
37 Rxe5ch! dxe5 38 d6ch! with at least a draw for White.
36 g5ch! ?
3 6 ... Kxg5
One point. Not 36 . . . Kf5?? 3 7 Re2 dis. ch.
37 Rc2
37 ... Qg3
Two points. White's clever defense took away h4 from the Black Queen, but this move is sufficient to win. One point if you saw that 38 Qe2 loses to 38 . . . Qh3ch 39 Kgl (39 Qh2 Rfl
mate) 3 9 .. . Rg3ch winning the Queen.
38 Qd2ch
38 ... Kf5
Two points. The only move to score.
39 Qg2
39 • • • Kxe4
One point. An extra point if you saw 39 Rel Qh4ch! Deduct five points for losing a Rook with 39 . . . Qxg2ch? 40 Kxg2 Kxe4 4 1 Rc4ch.
40 Rc4ch
40 ... Kxd5
One point. 40 .. . Kf5 also wins, so a point for it. Deduct four points for 40 .. . Kd3?? 4 1 Qc2ch Ke3 42 Re4 mate. White resigned.

8 a3
Two points. Gaining a slight advantage of two Bishops against Bishop and Knight (8 .. . Ba5 9 Nb3 is strong). Other moves are less forcing and allow Black a comfortable game, e.g. 8 Nb3 cxd4 9 Nbxd4 d5 or 9 .. . Nc6, equalizing. No points for any of these moves. 8 b3? would be a bad error, allowing 8 . .. Bc3 and 9 ... cxd4. Deduct two
points for this.
8 • . . Bxd2
Two points. No points for 9 Qxd2. After 9 . . . cxd4 10 Nxd4 (JO Qxd4 Nc6 followed by 1 J. . . d5) 10 . . . Bxg2 1 1 Kxg2 d5 again gives easy equality. 9 Nxd2 is met by 9 . . . Bxg2 10 Kxg2 cxd4 1 1 Nf3 d5 when Black has little to fear. No points. It was important for you to consider 9 .. . d5 at this point. If you intended 10 cxd5 Qxd5 - other moves also allow the isolation of Black's c-pawn - 1 1 dxc5 bxc5 ( 1 1 . . . Qxc5 1 2 Bb4) take a bonus point.
9 • . . cxd4
10 Bb4 !
White takes preventive action against Black's . . . d5. No points for 10 Nxd4 as after 10 .. . Bxg2 1 1 Kxg2 d5 Black has an even game. If Black replies 10 . . . d6, White plays 1 1 Qxd4 Ne8 1 2 Ne5 ! (not 12 Rfdl ? Nc6) 1 2 .. . Bxg2 1 3 Kxg2 Qf6 14 Qe4 ! with many threats. Two bonus points if you analyzed this. But deduct two points if you intended 14 Bxd6? which is weak: 14 .. . Nxd6 1 5 Qxd6 Rd8 16 Qc7 Na6 17 Qb7 Nc5 1 8 Qc7 Rac8 and Black wins. Deduct a point for 10 Bf4? d6 ! and White cannot recapture on d4 because of .. . e5.
10 . . . Re8
1 1 Bd6
Two points. No points if despite all the warnings you played
1 1 Nxd4 or 1 1 Qxd4 allowing the
early .. . d5. No other moves deserve
credit.
1 1 . . . Ne4
12 Qxd4
One point. The only move that comes into consideration; White must preserve his hold on d6. Deduct three points for 1 2 Nxd4 which loses a piece by l2 . . . Nxd6. Deduct one point for 1 2 Bb4 e5; no point for 1 2 Bf4 d5.
1 2 . . . Na6
13 b4
Three points. Expanding his spatial advantage while restricting the Black Knights. If now 1 3 .. . Nxd6 14 Qxd6 Qc7 1 5 Rfd l Qxc4 16 Ne5 wins the exchange; 16 . . . Qc8 17 Rae l Qb8 (1 7 .. . Bc6 18 b5) 18 Qxb8 R(either)xb8 19 Nxd7. Two bonus points if you saw this. 1 3 Rad 1 moves the wrong Rook; 13 Rfdl allows 1 3 .. . Nac5 (threatening . . . Nb3). No credit for either of these moves. 1 3 Ne5 Nac5 is unclear. White cannot win a pawn by 14 Bxc5 Nxc5 1 5 Bxb7 Nxb7 16 Qxd7 (16 Rfdl d6) 16 .. . Qxd7 17 Nxd7 because 1 7 .. . f6 traps the Knight.
13 . . . Rc8
Two points. A necessary precaution to the c4 pawn, which Black threatens to win after 1 4 .. . Nxd6. Deduct two points for 1 4 c5 which loses a pawn out of hand. 14 Ne5 Nxd6 1 5 Qxd6 Bxg2
16 Kxg2 f6 17 Nxd7 Rxc4 is unclear, though White is probably on top after 18 Rfd l . One point for this idea. After 14 Nd2 Nxd6 1 5 Qxd6 Bxg2 16 Kxg2 Black's defense has been considerably eased. After 16 .. . Rc6 1 7 Qd4 Nc7 1 8 b5 e5 1 9 Qe4 Rce6 Black is ready for 20 . . . d5. 14 b5 deserves no credit; Black defends easily by 1 4 .. . Nac5. Nor does 14 Rfc l , since this Rook is better on the d-file.
14 ... Nxd6
15 Qxd6
One point.
15 ... Nc7
16 Rfdl
Two points. Bringing the last White piece into action, and threatening to win a pawn. Nothing else is quite so strong. 16 c5 is worth a point; 16 .. . Nb5 17 Qd3 Nc7 1 8 cxb6 would suit White well, but 1 6 .. . bxc5 1 7 Rxc5 Nd5 is better for Black; any exchanges ease his position. 16 Ne5 is not decisive. Black has 16 . . . Bxg2 1 7 Kxg2 Re7 1 8 Rfdl Ne8 extricating himself. No points. No points either for 16 a4 which is too slow, giving Black time for . . . Qe 7.
16 ... Re7
1 7 Qd3
Three points. A difficult stage in the game. White has to decide how to convert his spatial advantage into something more tangible. 17 Ne5 scores only one point. After l7 . . . Bxg2 18 Kxg2 Ne8 ! 1 9 Qd3 (19 Nc6 Nxd6 20 Nxd8 Nxc4) 19 . . . Nf6 Black's position is much easier. The game move threatens both 18 Ne5 and - more importantly - 1 8 Ng5 Bxg2
19 Qxh7ch Kf8 20 Qh8 mate. If Black tries to emancipate himself by 17 . . . d5 18 cxd5 exd5 (18 .. . Nxd5 19 e4) 19 Ng5 g6 20 e4 wins at least a pawn. Two extra points if you saw these variations. 17 Rd2, intending to double Rooks on the d-file, is a mistake: l 7 .. . Nb5 1 8 Qd3 d 5 and Black can defen
�
. Deduct a point for 1 7 Rd2. Agam no points for 17 c5. 1 7 b5 leaves the c4 pawn weak: no points.1 7 ... Bxf3
18 Bxf3
One point. Nothing for other recaptures. The scope of the White Bishop is now enhanced and 18 . . . d5 is prevented: 1 9 cxd5 exd5 20
e4.
18 ... Ne8
1 9 Bb7!
Five points. The move played switches the Bishop to the queenside, where White controls more squares, and disrupts the harmony of the enemy pieces. 19 e4 is less flexible, but deserves two points. 1 9 Rd2 d6 20 R l d l has the demerit of leaving White's c4 pawn weak. No points for 1 9 c5 bxc5 20 bxc5 intending c5-c6, which is too committal.
19 ... Rc7
20 Ba6
One point. The completion of the maneuver outlined in the previous note. No other move scores.
20 ... Rc6
21 Qb3
Three points. Preventing 2 1 . . .d5 and improving the position of the Queen, e.g. 2 l . . .d5 22 Qa4 Rd6 (22 .. . R 7c7 23 Bb5 wins) 23 cxd5 Rxd5 24 Rxd5 followed by 25 Rc8 wins. Now 2 l . . .Nc7? would lose the exchange to 22 Bb7.
Two points for 2 1 e4, which also increases the pressure on
Black's position. 2 1 c5 allows 2 1 . . .d5, so no points. Also no points for 2 1 Bb5 Rd6 with freeing exchanges.
2 1 ... Qb8
22 Qa4
Two points. Threatening to win a pawn by 23 Rxd7 and improving the position of his Queen. Deduct a point for 22 c5 which loses a pawn, while 22 e4 allows counterplay via 22 .. . Qe5.
No points for 22 b5 - a positional error. However 22 Rd4, although slow, earns a point.
22 ... Rc7
23 Qb5
Two points. The Queen has finally arrived at its most aggressive position. Take two bonus points if you visualized this position when playing your 2 1 st move. 23 e4 just gains one point.
23 ... Nf6
24 f3
One point. Karpov intends to restrict the Black pieces still more by 25 e4. However 25 c5, three points, was stronger, when the White queenside pawns would begin an advance.
24 ... dS
25 cS
Two points. Still the most inc1s1ve continuation is this
