Chess Student Analysis
Grandmaster Marcin Kaminski's analysis of chess games played by his students. He gives special attention to the critical moments, and in pointing out areas of possible improvement.
Student - Opponent
1.Nf3 d5 2.c4 c6 3.e3 Nf6 4.Nc3 e6 5.d4 Nbd7 6.Bd3 dxc4 7.Bxc4 b5 8.Bd3 Bb7 9.0-0 a6 9...b4 is an interesting alternative. In my opinion Black has very good chances to equalize here, for instance 10.Ne4 Be7 11.Nxf6+ Nxf6 12.e4 0-0 and now: a) 13.Qe2 13...c5 14.dxc5 Nd7 or 14...Rc8 with an equal position. b) 13.e5 Nd7 14.Be4 Rb8 15.a3 bxa3 16.b4 (the best novelty of Chess Informant 78) 16...f5! 17.Bd3 Nb6 18.Bxa3 Nd5 19.Bc4 Qb6 and Black was okay in Khalifman-Bareev, Dortmund 2000. 10.e4 c5 11.d5 We have reached the main position of this line. Black has to choose between 11...Qc7 or 11...c4, as the other moves are not very promising. 11...exd5?! 12.exd5 Nxd5? A terrible mistake. Black should care more about his King than for a pawn. Anyway, White is much better in all variations and the analysis of this position is very good. 13.Nxd5 Bxd5 14.Bxb5! A simple tactic. After this Black doesn't win a pawn and, even worse, his King stays in the center without the smallest compensation. 14...axb5 15.Qxd5 Be7 16.Rd1 The strongest move. 16...Ra6? The immediate 16...Qc8? is losing after 17.Ng5. Instead, 16...Ra7 was the only chance, e.g. 17.b4 0-0 18.Be3 Qc7 19.bxc5 Nxc5 20.Ne5 and now the only move to keep the game going is 20...Ra6. 17.Bf4 17.Bg5 was another way to prevent 17...Rd6 and win the game. 17...Qc8 After 17...Re6 White can introduce the last piece with 18.a4! bxa4 19.Rxa4 Nb6 20.Qb3 Qc8 21.Qb5+ Kf8 22.Ra7, planning Be3, b4 or immediate b4. 18.Ng5 Rf6 18...Bxg5 19.Bxg5 Re6 20.Re1 is winning for White. 19.Bg3?
25.Nh7!!+ Rxh7 26.Qxh7 Re6 27.Qh8+ Ke7 28.Rxe6+ Qxe6 29.h3 is
only unclear.
21.Ne4
The rest is easy...
21...Re6 22.Nd6+ Bxd6 23.Bxd6 Qc6 24.Qg3 g5?
24...g6 25.Rac1
25.Qxg5 1-0
Opponent - Student
1.d4 c5 2.d5 f5
This line seems to be too risky for Black. I would not recommend that students play 2...f5 too often. White has many ways now to get a clear advantage.
3.g4!?
Of course 3.Nc3 is more popular, but with 3.g4 White tries to take advantage of Black's light-squared weakness immediately.
3...fxg4 4.e4 d6 5.h3
5.Bb5+ Bd7 (5...Nd7 6.Qxg4 a6 7.Be2 Ngf6 8.Qg2 g6 9.h4 looks very good for White.) 6.Bxd7+ Qxd7 7.h3 Nf6 8.Nc3 Na6 9.Bg5 gxh3 10.Nxh3 with good compensation for the sacrificed pawn.
5...Nf6 6.Nc3
A novelty. Instead, 6.hxg4 Bxg4 7.f3 Bd7 8.Nh3 Na6 9.Ng5 Qb6 10.Nd2 h6 11.Bh3 Bxh3 12.Rxh3 Nc7 13.c4 Rg8 14.Qa4+ Kd8 15.Ne6+ Nxe6 16.dxe6 g5 was seen in Belakovskaia-Ehlvest, Stratton Mountain 1999.
6...g6
6...Na6 would have been interesting. It covers the square e6 after ...Nc7 and to prepares ...b7-b5.
7.hxg4 Bxg4 8.f3
8...Bc8?
Wasting time. The move 8...Bd7 is much better. The square d7 is not needed for the Knight at b8, which should be developed on a6 and then moved to c7.
9.Nh3 Bg7 10.Nf4 Na6 11.Bb5+
This move wouldn't have been possible if Black had played 8...Bd7.
11...Kf7 12.a4
Avoiding the counterplay connected with ...b7-b5.
12...Nc7 13.Bc4 Re8 14.Qe2 e5!
Otherwise White could finish development with Bd2 and 0-0-0, and then start to attack Black's King on the open "g" and "h" lines.
15.dxe6+ Bxe6
Avoiding 15...Nxe6 16.Be3 Kf8 17.0-0-0 Qb6 18.Qh2 and White wins.
16.Nxe6 Nxe6
Due to the pair of Bishops, Black's King weakness, and weak pawns d6 and h7, White is more than compensated for the pawn.
17.Bg5
17.Be3 was also good.
17...h6 18.Be3 Nh5 19.Qg2?
White lost everything with this move. Better was 19.Qd3 Qb6 20.0-0-0 with advantage.
19...Bxc3+! 20.bxc3 Qf6 21.Kd2
21...Rad8?
The critical moment in the game. Black realizes that everything is fine and he loses his concentration! This is a typical mistake and it's rather hard to avoid. Even top players often lose their concentration and make big mistakes, like missing a piece "en prise" in one move. After 21...Nhf4 22.Qg4 d5 23.exd5 Rad8 24.Rxh6 Nxd5 25.Bxd5 Rxd5+ 26.Kc1 Qxc3 27.Qxg6+ Kf8 Black is winning.
22.Qg4
White could simply take a pawn with 22.Bxh6.
22...d5??
Why not defend the h6-pawn with 22...Rh8 instead?
23.Bxd5 Rxd5+ 24.exd5
It's over now.
24...Nef4 25.Rae1 Nxd5 26.Qd7+ Ne7 27.Bxc5 Qg5+ 28.Be3 Qa5 29.Bd4 Qg5+ 30.Kd1 Nf4 31.Re5 Qg2 32.Rhe1 Qxf3+ 33.Kc1 Nfd5 34.Rxd5, 1-0
After getting a good position Black made two blunders a row, 21...Rad8 and 22...d5. To strengthen your play work on your concentration and practice calculating variations deeper.
Student - Opponent
1.e4 c5 2.c3 Nf6 3.e5 Nd5 4.g3 d6
Another promising line for Black is 4...Nc6 5.Bg2 Qc7!
5.exd6 e6
After 5...Qxd6 6.Bg2 Nc6 7.Ne2 g6 8.d4 cxd4 9.Nxd4 Bg7 (9...Ndb4!?) 10.Nxc6 Qe6+! Black has no problems.
6.Bg2 Bxd6 7.Nf3 Nc6 8.d4
8.0-0 0-0 9.Na3 is another possibility, but White cannot count on an advantage there either: 9...Be7 10.d3 b6 11.Nc4 Bb7 12.a4 Qc7 13.Qe2 Rad8 with equal chances in Rozentalis-Rogers, 1993.
8...0-0 9.0-0 cxd4
The most often-played move. Other interesting lines are 9...b6 and 9...b5!?.
10.Nxd4 Nxd4
10...Bd7!?.
11.Qxd4 Qc7
12.Bxd5?
For the pawn Black gets terrific compensation - the Bishop pair, development, the "d" and "e" files are open for Black's Rooks, and light-squared weakness around the White King are surely worth the pawn. 12.Bd5? is a big strategic mistake. According to theory, the best continuation is 12.Nd2 which leads to an equal position. Tournament games shows that White can get small advantage.
12...Be5
Better than the immediate 12...exd5.
13.Qe4 exd5 14.Qxd5 Be6
The sequence 14...Bh3 15.Re1 Rad8 16.Qf3 Rfe8 guarantees good compensation too, but the game move is better.
15.Qf3 Rad8 16.Be3
White can save the game, but only if he develops the Queenside and exchanges some pieces - even if it costs him a material loss. This is a difficult position in which to offer advice.
16...Bd5
Black's pieces are placed perfectly. The plan of attack is very similar to the Marshall Gambit in the Ruy Lopez, where the typical method is to take advantage of the weak light squares by playing f7-f5-f4.
17.Qf5
If 17.Qg4 f5 18.Qh4 f4 followed by ...Rd6-h6 with a decisive attack.
17...g6 18.Qg5 f5
18...b6 is also interesting, when Black threatens to play ...Bb7 and ...Qc6. Probably the best defense would be 19.Bd4 which is much more concrete and better.
19.Bxa7?
Taking such a pawn is always dangerous. 19.Bd4 was much better, e.g. 19...b6 (19...Bxd4 20.cxd4 f4 21.Nc3 Bf3) 20.Bxe5 Qxe5 21.Nd2 Bb7 with very strong compensation.
19...Qc6?
If 19...f4 20.Bd4 Bxd4 21.cxd4 Rf5 with compensation. Better is 19...b6! 20.Qe3 (20.Re1 Bf6 is winning for Black) 20...f4 21.Qxb6 Qc8! 22.c4 Ba8 with the following position:
White cannot save himself.
20.Nd2 b6 21.Rfe1?
21.Qe3 Bc7 22.c4! complicates the position.
21...Bf6
Better than 21...Bc7.
22.Qe3 Rd6
White's position is difficult. He has developed pieces but the Bishop on a7 is lost.
23.Rad1
23.Qf4 Ra8 24.Bxb6 Qxb6 and 3 pawns for the piece. Black's Bishop pair is too strong in open positions.
23...Ra8 24.Bxb6 Qxb6
It is better to keep Queens on the board (25.Qf4), but that would hardly change the situation. White is already lost, and the rest of the game needs no commentary. White has no chance even to stir up complications; the end is a simple realization of material advantage.
25.a3 Qxe3 26.fxe3 Rb6 27.e4 fxe4 28.Nf1 Bc6 29.Rd2 Rab8 30.Rf2 Kg7 31.Ree2 Rb3 32.Ne3 Be7! 33.a4 Bc5 34.Kg2 Bxa4 35.h4 Bb5 36.Re1 Bd3 37.Kh3 Bxe3 38.Rxe3 Rxb2 39.Rxb2 Rxb2 40.g4 Kf6 41.Kg3 Ke5, 0-1
Opponent - Student
1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 Ne7 5.Qg4 A better option for White is 5.a3 Bxc3 6.bxc3 c5 which leads into main lines of the French Defense. If 6....b6 7.Qg4 Ng6 8.h4 gives White better chances. 5...c5 6.Qxg7 Rg8 7.Qh6 cxd4 8.a3 Qa5 8...Bxc3+ 9.bxc3 Qc7 is also promising for Black. 9.axb4 Qxa1 10.Nb5 Nf5 11.Qd2
11...Kd8
A very interesting novelty. Before now 11....Na6 was played,
but 11...Kd8 looks very logical as c6 is surely a much better place for the
Knight than a6. Also interesting is 11....Kd7 with the same idea.
12.Nf3
12.Ne2 Nc6 13.Ng3 a6 14.Nxf5 (14.Nd6 Nxd6 15.exd6 Nxb4;
14.Na3 Nxb4 15.Nxf5 exf5 16.Be2 Na2! 17.Qa5+ Ke7 18.Qc5+ Ke8)
14...exf5 15.Nd6 Nxe5 16.f4 Ng4 17.Nxf7+ Kc7; 12.Nd6 Nxd6 13.exd6. This
position would be even better if Black's King were on d7 (11....Kd7!?), although
Black has an advantage here after 13...Nc6.
12...Nc6 13.g3?
Waste of time. Also bad is 13.h3? Nxb4 14.g4 Na2!; but
13.c3!? dxc3 14.bxc3 a6 (14...a5 15.Bd3 and though Black is still better, White
gets some counter chances.) 15.Na3 with the idea h3, g4 could give White
better chances than in the game.
13...Qa4?!
13...Nxb4 looks stronger after 14.Be2 (14.Nfxd4 Nxd4
15.Nxd4 Na2 16.Nb3 Qb1 17.Bd3 Nxc1 18.0-0 Nxb3 19.cxb3 Qa2; 14.Bh3 Nxc2+ [A
new tactical possibility!14....Na2 is also possible.] 15.Qxc2 Qa5+ 16.Bd2
Qxb5 17.Bxf5 exf5 18.Nxd4 Qc4) 14...Na2 15.0-0 Nxc1 16.Rxc1 Qxb2.
14.Bd3
14.Nd6? Qxb4 (or 14...Nxe5) 15.c3 dxc3 16.bxc3 Qc5
17.Nxf7+ Kc7.
14...Nxb4?!
Unfortunately 14...Qxb4 is not as good as it looks after
15.Qxb4 Nxb4 16.Bxf5 exf5 17.Bg5+! Kd7 18.e6+! fxe6 19.Ne5+ Ke8 20.Nc7+ Kf8
21.Bh6+ Ke7 22.Nxa8 Bd7 23.Nc7 Rc8 and the position is unclear; for example
24.Bg5+ Kd6 25.Bf4!? Kxc7 26.Nd3+ Kb6 27.Nxb4 a5 28.Nd3 Rxc2.
Instead, 14...Bd7 was better. It doesn't look like it, but
White can open the "d" line very fast (by playing c3, Bxf5) and
then Black's King might be in danger. So 14....Bd7 not only develops a piece but
is a defensive move.
15.Bxf5 Qxb5
15...exf5 16.Nfxd4 and White finally gets compensation for the
sacrificed material.
16.Bxh7 Rh8 17.Bd3!?
17.Nxd4 Qb6 (17...Qc4 18.b3 Qc7 19.0-0 Rxh7 20.Qxb4 Qxe5
21.Ba3) 18.c3 is also interesting. Black already has lost his material
advantage and his bad coordination between pieces makes the position unclear.
17...Nxd3+ 18.cxd3 Qc5 19.0-0 Bd7 20.Qf4 Kc7 21.Nxd4?!
21.Bd2 would cause Black more trouble. Thanks to his
very active pieces White is already better.
21...Qe7 22.Be3
22.Bd2 is better again. White's idea is to prepare Bb4
now. Black must also remember that Nd4-f5 is a possibility.
22...Rac8?
