D52 Hoang,T.-Harvey,B., Cambridge Springs

Harvey, Bryan (1493) – Hoang, Truman (952)

D52 QGD Cambridge Springs Defense – Tampa (R3), May 15, 2010  [Notes by Hoffer]

This game was a missed opportunity for 9-year-old Truman against a player 6 years older and rated 600 points higher! This was a wild and very entertaining game!

1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Nbd7 5.Nf3

Bryan realizes he cannot try to win the d5 pawn as it would lose his Knight to the old Elephant Trap of: 5.cxd5 exd5 6.Nxd5?? (Better is 6.e3 c6 7.Bd3 Be7 8.Qc2 0–0 9.Nf3 Re8 10.0–0–0 Nf8 11.h4 Be6 12.Kb1 Rc8 13.Ka1 a6 14.Qb1 b5 15.Rc1 h6 16.Bf4 c5 17.dxc5 Bxc5 18.Nd4 Bd7 19.f3 Qb6 advantage Black, Bacrot,E (2594)-Karpov,A (2696), Cannes 2000 ½–½, 46 ) 6…Nxd5! 7.Bxd8 Bb4+ 8.Qd2 Kxd8–+ 9.e4 Re8 10.f3 f5 11.Bd3 Nf4 12.Kd1 Bxd2 13.Kxd2 Nxg2 14.Nh3 fxe4 15.fxe4 Nf6 16.Ng5 Nf4 17.Nf7+ Ke7 18.Ne5 Bd7 19.Rhg1 g6 20.Be2 Rad8 21.Ke3 Ne6 22.d5 Nc5 23.Kd4 b6 24.b4 Nb7 25.Raf1 c6 0–1 Mayet,K-Harrwitz,D, Berlin 1847.

5…c6 6.e3 Qa5

The Cambridge Springs Defense which has been used by Kasparov, Karpov, Smyslov, and Alekhine. The alternative of the Orthodox Defense is a boring fight for tempos behind a wall of pawns: 6…Be7 7.Qc2 0–0 8.Rd1 h6 9.Bf4 b6 10.Be2 Bb7 11.0–0 Nh5 12.Be5 f6 13.Bf4 Nxf4 14.exf4 f5 15.Rfe1 Bd6 16.Bd3 = Kasparov,G (2838)-Adianto,U (2598), Batumi 2001 ½–½, 49.

7.Bd3?!

After the game, Bryan realized he had played an inaccurate move here and asked me to suggest an improvement for White. Better is 7.Nd2! Bb4 8.Qc2 0–0 9.Be2!  [9.Bd3?? falls into another trap which costs White a piece. 9...dxc4! (discovering the attack 10...Qxg5) 10.Bxf6 cxd3! (a nice Zwischenzug) 11.Qxd3 Nxf6–+ winning a piece.] 9…c5 10.0–0 cxd4 11.Nb3 Qb6 12.Na4 Qc7 13.Nxd4 dxc4 14.Bxc4 Bd6 15.Rac1 Bxh2+ 16.Kh1 Bd6 17.Nb5 Qb8 White is better. Ivanchuk,V (2729)-Bacrot,E (2717), Wijk aan Zee 2006 ½–½, 43;

The Cambridge Springs gained a revival from: 7.cxd5 Nxd5 8.Qd2  (8.Qb3!? Bb4 9.Rc1 c5 10.Bc4!? 0–0 11.0–0 cxd4 12.exd4 Bxc3 13.bxc3 a6± 14.Rfe1 b6 15.Bd2 b5 16.Bxd5 exd5 17.Qxd5 Nb6± Kramnik,V (2785)-Dreev,A (2607), Moscow 2007 0–1, 40) 8…N7b6 9.Nxd5 Qxd2+ 10.Nxd2 exd5 11.Bd3 a5 12.a4 Bb4 13.Ke2 Bg4+ 14.f3 Bh5 15.h4 0–0 16.g4 Bg6 17.b3 Bxd3+ 18.Kxd3 Rfe8 19.Rac1 c5 20.Bf4 Rac8 21.dxc5 Nd7 22.c6 bxc6 23.Rhd1 Nc5+ 24.Kc2 f6 25.Nf1 Ne6 26.Bg3 Red8 27.Bf2 c5 28.Nd2 c4 29.bxc4 Nc5 30.e4 d4 31.Nb1?  (31.Ra1 d3+ 32.Kc1 Bxd2+ 33.Kxd2 Nb3+ 34.Kc3 Nxa1 35.Rxa1 d2 36.Rd1 Rb8 37.Bg3 Rb4 38.Bc7 Rc8 39.Bxa5 Rcxc4+ 40.Kxd2 Rxa4 41.Bc3 Kf7 Black has a slight edge) 31…d3+ 32.Kb2 d2 0–1 Karpov,A (2705)-Kasparov,G (2715), Moscow 1985.

A) 7…Bb4!? 8.Qc2 Ne4:

a) Another common Cambridge springs trap occurs after 9.Rc1?? Nxg5–+ 10.Nxg5 dxc4 0–1 Lylov,I (2251)-Novichkov,V (2405), Dubna 2001;

b) Not 9.Bxe4?! dxe4 10.Ne5 Nxe5 11.dxe5 Qxe5 12.Bf4 Qa5 13.0–0 f5 14.Rfd1 e5 15.Bg3 0–0 and Black stands better. Malinichev,K (2290)-Khruschiov,A (2453), Volodarskij 2007 0–1, 24;

8.Qc2??

Bryan falls into the very same trap as did Igor Lylov vs. Vadim Novichkov in his game in the note above. Much better is 8.cxd5 Nxc3 9.bxc3 Qxc3+ 10.Ke2 Qb2+ 11.Nd2 exd5 12.a3 (12.Bf4!?=) 12…Be7 (12…Bd6!?) 13.Bxe7 Kxe7 14.Re1 Nf6 (14…c5!) 15.Kf1 Re8 (15…Qc3) 16.Nf3 (White should have set up a Queen trap: 16.Nb3! Bg4 17.f3 Bxf3 18.gxf3 Qxh2 19.Re2 Qh1+ 20.Kf2 Qh2+ 21.Ke1 Qh1+ 22.Kd2 Qxf3 23.Qg1±) 16…Kf8 17.Ne5 Qc3 18.Qe2 Kg8 19.Rec1 Qa5 20.Rc5 Qc7 21.Qc2 Rxe5! 22.dxe5 Qxe5 23.Rb1 Qxh2 24.f3 h5 25.Bf5?

A very sloppy game indeed!

8…Nxg5–+ 9.Nxg5 dxc4 10.Bxc4 Qxg5 11.0–0 Nb6

This Knight may be better placed on the Kingside for defense. 11…Qd8 12.f4 Nf6 13.Qb3 g6 14.Rf3 Bg7 15.Raf1 0–0–+

12.Bd3 Bd6?!

Now that Truman has completed his piece winning combination, he should take a break to reanalyze the position. Black is ahead by a black squared Bishop. Therefore, a desperate White is poised to attack with f4-f5. Truman should consolidate his advantage and build a fortress around his King by with an impenetrable fianchetto as White does not have a black-squared Bishop to break in. Truman should then withdraw his Queen from vulnerability to tempo shots by keeping her on the dark squares, safely castle his King, cut off any counterplay (such as answering f4 with …f5) and finally develop his Queenside pieces. Better is 12…g6! 13.f4 Qe7 14.Ne4 Bg7 15.Rf3 0–0 16.g4 f5–+

13.Ne4 Qd5?!

When ahead like this, Black should play it safe and not subject his Queen to being a tempo target. Better is 13…Qe7 14.a4 Bd7 15.Qb3 0–0 16.Nxd6 Qxd6 17.e4 Qc7–+

14.f4 f5 15.Ng5 Be7 16.Nf3 Qd7?!

This move wastes two tempos. Truman wins easily as long as he completes his development! Better is 16…0–0 17.b3 Bd7–+

17.Ne5 Qc7 18.e4 Bf6?

Don't move the same piece repeatedly! It is much better to get your next piece out and well-developed, especially when you have yet to castle and develop your Queenside. Better is18…g6 19.Rad1 0–0 20.Rf3 Bd7–+

19.exf5 Bxe5?

Seven out of Truman's last eight moves have been with this dark squared Bishop or his Queen when he has not castled or developed Bc8 & Ra8! It's time to gain a tempo and attack the dangerous Bd3 with: Better is 19…Nd5! 20.Rae1 Nb4 21.Qe2 0–0 (21…Nxd3 22.Nxd3 0–0 23.fxe6 looks too dangerous.) 22.Bc4 Nd5 23.fxe6 Bxe6 24.Nxc6 (24.f5 Bf7 25.Qg4 Rae8 26.Nxf7 Qxf7–+; 24.Bxd5 Bxd5 25.Qd3 Rae8+-) 24…Nxf4 25.Bxe6+ Kh8 26.Rxf4 Qxf4–+

20.fxe5 0–0?

Black finally castles, but it is right into White's attack. Truman should have played 20…Nd5! 21.fxe6 Ne3 22.Qb3 Nxf1 23.Rxf1 Qe7 24.Rf7 Qxe6–+

21.f6! g6?

This should have been the losing move as it invites a Bishop sac at g6. On 21…gxf6 22.Rxf6 Rxf6 23.exf6 e5 24.Qf2 Be6 (24…Nd5 25.Qg3+ Kh8 26.dxe5 with compensation) 25.Re1 Nd5 26.Qh4 Qf7 27.Rxe5 (27.dxe5 Kh8) 27…Nxf6 28.Rg5+ Kf8 29.Qh6+ Ke8 30.Rg7 Qf8 31.Bxh7 Rc8 32.Qg5 Nxh7 33.Rxh7 Rd8 34.Rxb7 Bd7 35.Rxa7 Qd6 36.Qe5+ Qxe5 37.dxe5 Rb8 38.b3 Rb5 39.h4 Rxe5 White has the edge;

Best is 21…Kh8! 22.fxg7+ Qxg7 23.Rxf8+ Qxf8 24.Rf1 Qb4 25.Qf2 Qe7 26.Qf3 Bd7 27.Qh5 Be8  (27…Kg8 28.Rf6 Qg7 29.Bxh7+ Qxh7 30.Rg6+ Qxg6 31.Qxg6+ Kh8 32.h4 Re8 33.h5 Nd5 34.g4 Re7 35.g5 b6 36.Kf2 Bc8 37.Kf3 Ba6 38.h6 Bc4 39.b3 Bb5 40.Kg3+-) 28.Rf8+  (28.Qh6? Nd7!) 28…Kg7 29.Qxh7+  (29.Rxe8 Rxe8 30.Qxh7+ Kf8 31.Qh8+ Kf7 32.Qh7+=) 29…Kxf8 30.Qh8+ Kf7 31.Qh7+ Kf8 32.Qh8+=

22.Bxg6!+-

This is the second lead change.

22…hxg6

There is no defense. 22…Nd5 23.Rf3+-.

23.Qxg6+ Kh8 24.Rf3 Qh7 25.Rh3 Qxh3 26.gxh3??

Incredibly, Bryan was apparently so thrilled to capture Truman's Queen, he misses MATE-IN-ONE, and loses his own Queen in the process! Better is 26.Qg7#, in my country.

26…Rg8–+

This is the third lead change.

27.Qxg8+ Kxg8 28.Kf2 Bd7 29.Rg1+ Kf7 30.Rg7+ Kf8 31.h4 Rd8??+-

This is the fourth lead change. Truman totally disregards the danger from White running his h-pawn, which had to be addressed immediately with 31…Be8! 32.Rxb7 Rd8 33.Rxa7 Rxd4 34.Rh7 Rd2+ 35.Kg3 Rxb2 36.Rh8+ Kf7 37.Rh7+ Kg8–+

32.Rh7??

Passed pawns must be pushed! Neither one of these guys seems to have the patience to analyze a winning transition into the endgame. They are both playing scared. It is vital to remain active and not passive in the endgame. Better is 32.h5! Be8 33.h6 Rxd4  (33…Bg6 34.Rxg6 Rd7 35.Rg7 Rxg7 36.hxg7+ Kf7 37.Kf3+-) 34.h7 Rh4 35.Kg3 Rh6 36.Rg8+ Kf7 37.h8Q Rxh8 38.Rxh8 Nd7 39.Rh7+ Kf8 40.Kf4 Nc5 41.Rh8+ Kf7 42.h4 Nd3+ 43.Ke4 Nf2+ 44.Kd4 c5+ 45.Kxc5 Ne4+ 46.Kd4 Ng3 47.Rh7+ Kf8 48.Rxb7+-

32…Kg8–+

This is the fifth lead change. This move works is the King goes into the corner on the next move to disrupt the pawn most likely to Queen. More efficient is 32…Be8! 33.h5 Rxd4 34.Rh8+ Kf7 35.Kg3 Rd1 36.Rh7+ Kg8 37.Rg7+ Kf8 38.h6 Rg1+ 39.Kf4 Rxg7 40.hxg7+ Kg8 41.Ke4 Bg6+–+.

33.Rg7+ Kf8??+-

This is the sixth lead change. The King always needs to be in front of the pawn threatening to promote. The f7 pawn was not a threat as an immediate f7 hangs the supporting Rg7.  Better is 33…Kh8 34.Rg4 Rg8 35.Rf4 Kh7–+

34.Rh7??–+

This is the seventh lead change! White again puts his Rook in the way of keeping his h-pawn from scoring a touchdown! It is becoming clear White hopes to draw. Allowing any consideration of drawing into your mind is POISON. This is an excellent example. Offering draws is a sign of weakness and lack of confidence. Accepting such an offer should only be done with major suspicion and after sober analysis of the position. It should only be done if you are busted or playing a far superior opponent.  Better is 34.h5! Be8 35.h6 Rxd4 36.h7 Rh4 37.Kg3 Rh6 38.Rg8+ Kf7 39.h8Q Rxh8 40.Rxh8+-

34…Be8 35.Rh8+ Kf7 36.Rh7+  ½–½!?

Bryan correctly offers the draw here as he realized he was lost. Truman innocently accepted the offer in a position that would require a major blunder to lose. Never accept draws in a position such as this, especially when you have nothing to lose. Make 'em prove it! White's position was hopeless. Play may have best continued with:

a) 36…Kg8 37.Rxb7 Rxd4 38.Rxa7 Rxh4 39.Kg3 Re4 40.Re7 Bd7 41.b4 Rxb4 42.Rg7+ Kh8 43.Rf7 Rb5 44.Rf8+ Kh7 45.a4 Ra5 46.Rb8 Nc8 47.Rb4 c5 48.Rg4 Nb6 49.f7 Ra8 50.a5 Nd5 51.Rc4 Kg7 52.f8Q+ Kxf8 53.Rxc5 Nb4 54.h4 Nd3 55.Rc3 Nxe5 56.Ra3 Nc4 57.Ra2 Rxa5 58.Rf2+ Ke7 59.Rf3 Nd6-+

b) Or 36…Kg6 37.Rg7+ Kh5 38.f7 Bxf7 39.Rxf7 Rd7 40.Rf6 Rxd4 41.Rxe6 Rd2+ 42.Kg3 Nd5 43.Re8 Rxb2 44.Rh8+ Kg6 45.h5+ Kf5 46.h6 Kg6 47.h7 Rxa2 48.e6 Re2 49.Rb8 Re3+ 50.Kf2 Kxh7 51.Rxb7+ Kg6 52.Rxa7 Rxe6–+
