The Tarrasch Trap is a variation of the Ruy Lopez, Steinitz Defense, where White wins material through a direct tactical sequence straight out of the opening. It is also called the Dresden Trap since the seminal game was played there (Tarrasch-Marco, Dresden 1892). This Trap is particularly instructive because it combines many tactical elements: Remove the Guard, Pin, Skewer, Fork and Weak Back Rank.
Here's Tarrasch defeating Marco with the Tarrasch Trap: 1. e4 e5 2. Nf3 Nc6 3. Bb5 d6 4. d4 Bd7 (Black avoids giving up the center with 4 ... exd4 5. Nxd4) 5. Nc3 Nf6 6. 0-0 Be7 7. Re1:

Black's position with the centralized minor pieces is known as the Blackburne Formation. Here the move 7. Re1 sets up the Tarrasch Trap, since the Pe4 is now defended twice. Black does best to play 7 ... exd4 which gives White a distinct spatial advantage (8. Nxd4 Nxd4 9. Bxd7+ Qxd7 10. Qxd4), but doesn't lose any material. Instead 7 ... 0-0? falls into the Trap: 8. Bxc6 (not 8. dxe5!? Nxe5 and the Trap is off) Bxc6 (if 8 ... bxc6 9. dxe5 dxe5 10. Nxe5 wins a Pawn, a typical motif in the Ruy Lopez) 9. dxe5 dxe5 10. Qxd8 (10. Nxe5!? Qxd1 forces the Re1 or the Nc3 off the Pe4 and Black holds the balance) Raxd8 (we'll examine 10 ... Rfxd8 later) 11. Nxe5 Bxe4?! (+1.71 versus 11 ... Bd7 +0.84 per Junior 8):

This appears to win back the Pawn, compared to 11 ... Nxe4?? 12. Nxc6 (Remove the Guard) and White wins a piece (12 ... bxc6 13. Nxe4). But after 11 ... Bxe4?! White plays 12. Nxe4 Nxe4 13. Nd3 blocking the d file (13. Rxe4?? Rd1+ mates) with a Skewer on the Ne4 and the Be7. The game continued 13 ... f5 14. f3 Bc5+ 15. Nxc5 (not 15. Kf1!? Bb6 holds) Nxc5 16. Bg5 Rd5 (if 16 ... Rde8 17. Be7 wins the Exchange; on 16 ... Rd7 17. Be7 Na4 18. Bxf8 Kxf8 +2.21/15 [50M] per Crafty) and White finished it off with 17. Be7 Re8 18. c4 1-0:

White wins the exchange (18 ... Rxe7 19. Rxe7 or 19. cxd5), otherwise Black loses the Nc5 if the Rd5 moves.
Now let's evaluate 10 ... Rfxd8 instead, to see how it alters the Tarrasch Trap theme. White would still play 11. Nxe5 Bxe4?! (Black should bail out down a Pawn with 11 ... Bd7 or 11 ... Be8) 12. Nxe4 Nxe4 13. Nd3 f5 14. f3 Bc5+ 15. Kf1! (not 15. Nxc5 Nxc5 16. Bg5 Rd7 =) Rf8 16. Ke2 (not 16. fxe4!? fxe4 regains the piece):

Both the Bc5 and the Ne4 are under attack, so White wins a piece.
Here's a training game I played against a student: 1. e4 e5 2. Nf3 Nc6 3. d4 d6!? 4. Bb5 (transposing to the Ruy Lopez) Bd7 5. Nc3 Nf6 6. 0-0 a6? 7. Bxc6 Bxc6 8. dxe5 dxe5 9. Qxd8+ Rxd8 10. Nxe5:

This game resembles the Tarrasch Trap, with the added benefit that Black hasn't castled yet so the open e file might cause real problems (like 10 ... Bxe4?! 11. Re1 Bf5 12. Ng6+). Play continued 10 ... Nxe4?! (10 ... Bd7 is better) 11. Nxc6 (Remove the Guard) Nxc3 12. Nxd8 and here Black slipped up with 12 ... Kxd8?? allowing 13. bxc3 and White won a Rook and the game. Instead the Zwischenzug 12 ... Ne2+ 13. Kh1 Kxd8 leaves Black down the exchange, although the Ne2 will be hard to extricate after 14. Be3.
Another game I recently played as White on the Internet, where the Steinitz Defense to the Ruy Lopez seems to be fairly popular: 1. e4 e5 2. Nf3 Nc6 3. Bb5 d6 4. d4 Bd7 5. 0-0 Nf6 6. Nc3 Be7 7. Re1 0-0? 8. Bxc6 Bxc6 9. dxe5 dxe5 10. Qxd8 Raxd8 11. Nxe5 Bb4 12. Nxc6 bxc6 13. f3 Rfe8 14. Be3 c5 15. Red1:

And White won the endgame (1-0).
Tarrasch published his analysis of this variation in the February 1891 issue of "Deutsche Shachzeitung" one year before his game against Marco, and reportedly he only spent four minutes on the entire game. Be prepared! :-)

The Desperado Line is an important subvariation of the Fork Trick tactic. After 4 ... Nxe4! White interposes 5. Bxf7+!? forcing 5 ... Kxf7 and then recapturing 6. Nxe4, but this allows Black to gain the center with 6 ... d5:
The results are overwhelmingly in Black's favor (75% wins), as Black gains a classic center (Pawns at d5 & e5) plus the Two Bishops on an open board. The Black King is temporarily exposed but often hides at g8 or retreats to e8, and then Black completes development while castling by hand. Using the chessgames.com database with 39 reference games, here are White's choices for Move 7: 7. Neg5+ 18, 7. Ng3 14, 7. Nc3 5 and 7. Nfg5+ 2.
1) 7. Neg5+ Kg8 and now White plays 8. d3 or 8. d4 to protect the Ng5, otherwise 8 ... e4 hits the Nf3 and wins a piece (Remove the Defender).
a) Lenzer-Lasker (Germany, 1913): 8. d3 h6 9. Nh3 g5 (threat 10 ... g4) 10. Nd2 Rh7 11. f3 Bxh3 12. gxh3 Rf7 13. Nb3 Qf6 14. Rf1 Re8:

Black has a clear advantage and won after 15. Qe2 Re6 16. Bd2 Nd4 17. Qd1 Nxf3+ 18. Ke2 Ng1+ 19. Ke3 Bc5+ 20. d4 exd4+ 21. Kd3 Qg6+ 22. Rf5 Qxf5# 0-1. Extra credit if you work out the continuation after 20. Nxc5 instead.
b) Instead of 8. d3 h6 9. Nh3 g5 10. Nd2, I ran 10. Nhg1 through Fritz 7 which suggested 10 ... Rh7 11. Ne2 Qd6 12. Be3 Rf7 13. 0-0 Bg7 [-0.75/11] and Black has a fine center and a great game:

c) Ronga-Sinkovics (Hungary, 1996): 8. d4 h6 9. Nh3 Bg4 10. dxe5 Nxe5 11. Nhg1 Bc5 12. Bf4 Ng6 13. Bg3 Qd7 14. Qd3 Re8+ 15. Ne2 Bf5 16. Qd2 Be4 17. 0-0-0 Bxf3 18. gxf3 c6:

Play continued 19. f4 Ne7 20. Nd4 Bxd4 21. Qxd4 b6 22. Rde1 Nf5 23. Qd3 Kh7 24. Re5 Rxe5 25. fxe5 c5 26. c4 d4 and Black won (0-1, 40).
2) 7. Ng3 is best met by 7 ... e4 kicking the Nf3 back to g1.
a) Hubel-Kuhne (Germany, 1918): 8. Ng1 Bc5 9. Nxe4!? Re8 (9 ... dxe4? 10. Qh5+ & 11. Qxc5) 10. d3 Kg8 11. Qh5 Bb4+ 12. c3 dxe4 13. cxb4 exd3+ 14. Be3 Nxb4 15. Kf1 Nc2 16. Rc1 d2 17. Rd1:

Black to Play and Win: 17 ... Rxe3! 18. fxe3 Bg4! 0-1 (19. Qxg4 Nxe3+ & 20 ... Nxg4, otherwise 19 ... Bxd1).
b) Beres-Odler (Slovakia 2000): 8. Ng1 Bc5 9. N1e2 Bg4 10. h3 Bxe2 11. Qxe2 Rf8 12. 0-0 Kg8 13. d3 Nd4 14. Qd1 Qh4:

Black has a big advantage in space plus pressure against f2. 15. dxe4 dxe4 16. Kh1 Rad8 17. Qg4 Qxg4 18. hxg4 Nxc2 and Black won (0-1, 38).
3) 7. Nc3 is also best answered with 7 ... e4. Wall-Watt (Sunnyvale, 1986): 8. Ng1 Bf5 9. Nge2 d4 10. Ng3?! dxc3 11. Nxf5 Qf6! (Double Attack) 12. Ng3 cxb2 and Black won quickly (0-1, 22).
4) 7. Nfg5+?! is tricky but easily met by either 7 ... Ke8 or 7 ... Kg8 and both White Knights are under attack.
a) Fritz 7 gives 7. Nfg5+?! Ke8 8. Qh5+ g6 9. Qf3 Bf5 (blocking access to the f7 and f6 squares) 10. d3 h6 [-2.00/11]. White loses a Knight.
b) Black must be extra careful to avoid 7. Nfg5+?! Kg8 8. Qf3 dxe4? 9. Qf7#, or 8 ... Qe7 9. Ng3 Qxg5? 10. Qxd5+ with Mate in Two. There are other lines involving Qb3+ mating if Black doesn't mind the crucial a2-g8 diagonal, thus 7 ... Ke8 is actually safer than 7 ... Kg8. If Black does play 7 ... Kg8, Fritz 7 says 8. Qf3 Qd7 9. Ng3 h6 10. Nh3 Nb4 [-1.56/13] as best play.
The Fork Trick is analogous to the Fried Liver Attack in that all students should review the material, with the expressed understanding that you won't see these lines very often as you face better opposition. Good Luck! =) 2/5/2008
Here are three games from a Game in 15 minutes Blitz tournament in South Bend, Indiana.
1/21/2008
C) 6. Bb5
6. Bb5 pins the Nc6 so White will regain the Pawn after 6 ... dxe4 7. Nxe5:

Black now has two good moves: 7 ... Qd5 and 7 ... Qg5.
1) Seymour-Steinitz (London, 1875): 7 ... Qd5 8. Bxc6+ bxc6 9. Ng4 Ba6 10. Ne3 Qd4 11. f3 Bc5 12. fxe4 0-0:

Black has sacrificed a Pawn for a huge lead in development and soon gains a crushing attack: 13. d3 f5 14. Qf3 Rae8 15. Nxf5 Rxf5! 16. Qxf5 Bb4+ 17. Kd1 (17. c3 Qxd3) Bxd3! 18. Qg5 (18. cxd3 Qxd3+) Bxc2+! 19. Kxc2 Qxe4+ 20. Kb3 Rb8 21. a3 Bd2+ 22. Ka2 Qc4+ 23. Kb1 Qd3+ 24. Ka2 Qb3+ 25. Kb1 Bxg5 0-1.
2) Schmidt-Lasker (New York, 1893): 7 ... Qd5 8. Bxc6+ bxc6 9. d4 Ba6 10. c3 Bd6 11. Qb3 0-0 12. Qxd5 cxd5:

The Queen trade leads to an interesting endgame, although Black has the Two Bishops and the better development. 13. Nd7 Rfe8 14. Be3 h6 15. h4 Kh7 16. Nc5 Bc8 17. Kd2 Rf8 18. b3 f5 19. g3 f4 20. gxf4 Bxf4 21. Bxf4 Rxf4 22. Rh2 Bg4 23. Rg1 Raf8 24. Ke1 h5 25. Rg3 R8f7 26. Rhg2 R4f6 27. Nb7 Bf3 28. Rh2 e3! 29. fxe3 Bg4 30. c4 dxc4 31. bxc4 Rb6 32. Nd8 (32. Nc5 Rb1+ 33. Kd2 Rb2+) Rf8 33. Rgg2 Rxd8 34. Rc2 Rb1+ 35. Kd2 Bf5 0-1.
3) 7 ... Qg5 is noteworthy because the chessgames.com database contains 5 games and Black won all 5:
a) Dietmar-Basagic (Hartberg, 1991): 7 ... Qg5 8. Nxc6 Qxb5 9. Nd4 Qe5 10. Ne2 Bf5 11. Ng3 Bg6 12. 0-0 0-0-0 13. Qe2 Bd6 14. c3 Rhe8 15. f4 exf3 16. Qxe5 Bxe5 17. Rxf3 Rd3 18. Kf2 Rxf3+ 19. Kxf3 Bd3 (Black maintains a strong bind) 20. b3 Bf6 21. Bb2 h5! 22. Nf1 (22. Nxh5? Be2+) Re2 23. Rd1 g5 24. h3 g4+ 25. hxg4 hxg4+ 26. Kxg4 Rxg2+ 27. Kh3 Bxf1 28. Rxf1 Rxd2 29. Rxf6 Rxb2 30. Rxf7 b6! 31. b4 Rxa2 32. Kg4 Rg2+ 33. Kh3 Rc2 34. Rf3 Kb7 0-1. The R&P endgame is an easy win.
b) Buzinger-Castiglione (Slovakia, 1993): 7 ... Qg5 8. Nxc6 Qxb5 9. Nd4 Qg5 10. Rg1 (10. 0-0? Bh3) Bc5 11. d3 Qe5 12. Ne2 exd3 13. Qxd3 Bf5 14. Qd1 Rd8 15. Bd2 0-0 (Black smartly develops instead of grabbing Pawns) 16. Qc1 Rfe8 17. Be3 Bxe3 18. fxe3 Qxh2 19. Kf2 Qe5 20. Nd4 Rxd4! 21. exd4 Qe2+ 22. Kg3 Qg4+ 23. Kf2 (23. Kh2 Qh4#) Qxd4+ 24. Kf1 Bd3+! 25. cxd3 Qxd3+ 26. Kf2 Re2+ 0-1. Great mating attack which concludes after 27. Kf1 Rd2+ 28. Ke1 Qe2#.
c) Rohan-Skacel (Czechoslovakia, 1996): 7 ... Qg5 8. d4 Qxg2 9. Rf1 Bd6 10. Nxc6 a6! 11. Ba4 Bd7 12. Be3 bxc6 13. Qd2 Qf3 14. h4 0-0 15. Qe2 Qxe2+ 16. Kxe2 f5 17. Bb3+ Kh8 18. d5!? f4 19. Bd4? (19. Bd2) c5 0-1. Black wins the exchange after 20. Bc3 Bb5+.
d) Olsen-Bryn (Tromso, 2006): 7 ... Qg5 8. d4 Qxg2 9. Rf1 a6 10. Bxc6+ bxc6 11. Qh5 g6 12. Qg5 Qxg5 13. Bxg5 Bg7 14. Bf4 c5 15. dxc5 g5 16. Bg3 (16. Bxg5? Bxe5) f5 17. f4 Bxe5 18. fxe5 f4 19. Bf2 e3 20. Bg1 Bh3 21. Rf3 Bg2 0-1. After pocketing the exchange, Black's protected passed Pawns are decisive.
e) Flermoen-Lie (Tromso, 2007): 7 ... Qg5 8. Nxc6 Qxb5 9. Nd4 Qe5 10. Nb3 Bd6 11. Qe2 (11. 0-0? Qxh2#) Bf5 12. c3 0-0 13. Nd4 Bd7 14. b3 Rae8 15. Bb2 Qg5 16. h3 c5 17. Nc2 Qxg2 18. 0-0-0 Qf3 19. Qxf3 exf3 20. c4 Re2 21. Rdf1 Rfe8 22. Ne3 f6 23. h4 h5 24. Rfg1 Kf7 25. Nd5 Rxf2 26. Rxg7+!? Kxg7 27. Nxf6 (the Discovered Check will regain some material, except ...) Ree2 28. Rg1+ Kf7 0-1. 29. Nxd7 Rxd2 and White gets killed on the second rank.
D) 6. Qe2
6. Qe2 wins the Pawn right back (6 ... dxc4 7. Qxc4) but after 7 ... Be6 Black has the Two Bishops on an open board:

1) Rysan-Drtina (Slovakia, 1994): 8. Qa4 f6 9. d3 a6!:

White must play 10. c3 or 10. c4 to give the Qa4 an escape square. Instead White missed the danger and lost after 10. Nc3?? Bb4 0-1 as the Queen is trapped with 11 ... b5.
2) NN-TP (Internet, 2004): 8. Qb5 Qd5 9. Qxb7?? (White wins material, yes?) Qxe4+ (no) 10. Kf1 Rb8 11. Qxc7 Qxc2 12. Nxe5? (White wins material, yes?) Qd1# (no) 0-1. Gotta love miniatures. ;>D
E) 6. Nc3
6. Nc3? loses a Pawn to 6 ... dxc4 and Black is better:

1) Anasco-Massenzano (Argentina, 1994): 7. Qe2 Bg4 8. Qxc4!? Bxf3 9. gxf3 Nd4 10. Qd3 Qf6 11. Nd5 Qxf3 12. Qxf3 (12. Nxc7+?! Kd8 13. Nxa8? Qxh1#) Nxf3+ 13. Ke2 Nd4+ 14. Kd1 0-0-0 (clever play by Black) 15. Nc3 f5 16. Ne2 Nf3 17. h4 Be7 18. Ng3? Nxh4 19. Ke2 e4 20. b3 Bf6 21. Rb1 g5 22. Ba3 Rhe8 23. Rbd1 f4 24. Nh5 Be5 25. Bb4 Re6 26. Rdg1 Nf3 27. Rd1 Nd4+ 28. Kf1 Nxc2 29. Ba5 e3 (White is lost) 30. Nxf4 Bxf4 31. Rxh7? e2+ 0-1.
F) 6. Bb3
6. Bb3? dxe4 and the Nf3 must retreat to g1, leaving White down a Pawn:

1) Cassar-Payet (Moscow, 1994): 7. Ng1 Bf5 8. g4!? Bg6 9. f3?! Bc5 10. Qe2 Qh4+ 11. Kd1 Qf2 12. Qxf2 Bxf2 13. Nh3 Bb6 14. Bd5 exf3 15. Bxf3 Nd4 16. Bxb7 Rb8 17. c3 Nc2 18. Bc6+ Ke7 19. Rb1 Ne3+ 20. dxe3 Bxb1 and Black won (0-1, 46).
G) 6. Nf6+
6. Nf6+ returns the piece to ruin Black's Pawns, although this leaves Black up a Pawn after 6 ... gxf6:

1) Fluck-Diehle (Marburg, 2000): 7. Bb5 Qd6 8. d3?? Qb4+ 9. Bd2 Qxb5 and Black won (0-1, 15).
H) 5. Nxe5
Instead of 5. Nxe4 d5 leading to the previous Move 6 options, 5. Nxe5?! is a rare sacrifice which I have seen more than once on the Internet. White may be so startled by Black's play (4 ... Nxe4!) that they want to "get even" for such bold audacity. Or perhaps White is hoping for 5 ... Nxe5 6. Qe2 (6. Nxe4 d5 still works - 7. Qe2 dxe4 8. Qxe4 Qe7) Nxc4 7. Nxe4 (7. Qxe4+ Qe7) Nb6? 8. Nf6# or 9. Nd6#. So instead Black should play 7 ... Qe7 8. Qxc4 f5 winning a piece.
I) 5. 0-0
Another variant from the Fork Trick can occur when White plays 5. 0-0!? turning the opening into an intentional Pawn sacrifice. 5 ... Nxc3 6. dxc3 is the Boden-Kieseritzky Gambit by transposition and Black must endure some pressure to keep the Pawn plus (6 ... f6 7. Nh4 g6) and eventually untangle.
Next time we'll cover the Desperado Line where White answers 4 ... Nxe4! with 5. Bxf7+!? Kxf7 6. Nxe4 and examine further play for both sides. 11/12/2007
The Fork Trick is a stock tactic that all 1. e4 e5 players should know. It frequently occurs in beginner games simply because inexperienced players are taught two sound opening principles: Knights before Bishops, and develop your KB to an active square. The key position most commonly arises from the Giuoco Piano, Two Knights Defense with 1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Nc3?! or else the Four Knights with 4. Bc4?!:

This exact formation can occur by transposition in the Vienna Game (1. e4 e5 2. Nc3) and Bishop's Opening (1. e4 e5 2. Bc4). Now Black plays 4 ... Nxe4! which is a sham sacrifice, since 5. Nxe4 d5 immediately regains the piece:

From here Black wins over 50% of all games, suggesting that the Fork Trick not only equalizes but gives Black the better game. Notice Black has the only Pawn in the center, plus open lines for both Bishops to develop, moreover Black often gains the Two Bishops which is a big advantage on an open board. The chessgames.com database contains 102 games with the Fork Trick, and these statistics for White at Move 6:
Source: http://www.chessgames.com/perl/explorer?node=1510412&move=6&moves=e4.e5.Nf3.Nc6.Bc4.Nf6.Nc3.Nxe4.Nxe4.d5&nodes=21720.21721.21722.21723.24145.24146.24098.24479.1510411.1510412
A) 6. Bd3
6. Bd3 is the most popular choice and scores best for White (40% win, 30% draw, 30% loss) out of the Move 6 options. Black usually responds 6 ... dxe4 7. Bxe4 Bd6 to defend the Pe5 (otherwise 8. Bxc6 & 9. Nxe5), and now the results become more equal (37% win, 32% draw, 32% loss)

1) Forgacs-Caro (Coburg, 1904): 8. d4 Nxd4 9. Nxd4 exd4 10. Qxd4 0-0 11. Bd2 Qe7 12. 0-0-0 Be5 13. Qe3 c5:

This middlegame looks even, although Black has more space. The game went 14. Bc3 Re8 15. Rhe1 Bxc3 16. Qxc3 Be6 17. f4 Qc7 18. Qf3 Qb6 19. f5?! (19. a3) Bxa2 20. Bxb7? Qh6+ 0-1 (21. Rd2 Rxe1+, or 21. Qe3 Rxe3).
2) Tarrasch-Lasker (Berlin, 1916): 8. d4 exd4 9. Nxd4 0-0 10. Be3 Qh4 11. Bxc6 bxc6 12. g3 Qh3 13. Qe2 c5 14. Nb3 Bg4 15. Qf1 Qh5:

White has very weak light squares on the Kingside, meanwhile the White King is stuck in the center. Black closed it out with 16. Nd2 Rfe8 17. Rg1 Rab8 18. Nc4 Be5 19. h3!? Bxh3 20. Qe2 Bg4 21. Qd3 Rbd8 22. Nxe5 (Desperation) Rxd3 23. Nxd3 Rxe3+! 0-1 (24. fxe3 Qh2).
3) Tartakower-Reti (Vienna, 1920): 8. d4 exd4 9. Bxc6+ bxc6 10. Qxd4 0-0 11. 0-0 Bf5 12. b3 c5 13. Qc3 Qd7 14. Ba3 Qb5:
White is much more active here versus the previous game, yet Black has the Two Bishops. Play went 15. Rfe1 Rfe8 16. Ne5 Re6?! 17. Nxf7! Rae8 (17 ... Rxe1+ 18. Rxe1 Kxf7 19. Qf3) 18. Rxe6 Rxe6 19. Bb2! Bf8 (19 ... Kxf7 20. Qxg7+) 20. Ng5 Rg6 21. Qf3! Qd7 (21 ... Rxg5 22. Qd5+ Kh8 23. Qf7 Qb8 24. h4) 22. Rd1 Rd6 23. Rxd6 Qxd6 24. h4 h6 25. Qxf5 hxg5 26. hxg5 Qd1+ 27. Kh2 Qh5+ 28. Kg3 Bd6+ 29. Be5 Qe2 30. Bxd6 cxd6 31. g6 1-0. A famous win for White out of the Fork Trick in the opening.
4) Those three games featured 8. d4 opening the center, but White does far worse with 8. d3 because the Be4 is awkwardly placed. Chavez-Sagalchik (Alajuela, 2006): 8. d3 Ne7 (8 ... f5!? 9. Bxc6+ saves the piece) 9. 0-0?! (9. Nd2 f5 10. Bf3) f5 10. Bg5 fxe4 11. Bxe7 Qxe7 12. dxe4 0-0:

Black is a piece up with an easy win: 13. Qd5+ Kh8 14. g3?? Rxf3 15. Rad1 Bh3 16. Rd3 Qf6 17. Qxb7 Rf8 18. Qxa7 Rxd3 19. cxd3 Qf3 20. d4 Qg2# 0-1.
B) 6. Bxd5
6. Bxd5 is the direct approach, forcing 6 ... Qxd5 and now White can either defend the Ne4 with 7. d3 or else retreat 7. Nc3 hitting the Qd5. This line has personal significance as my first training games ever with Peter and Michael Chen both reached this position:

1) Peter-Tony (St. Joseph, 4/7/06): 7. Nc3 Qd8 8. 0-0 Bg4 9. Re1 Be7 10. h3 Bxf3 11. Qxf3 Nd4 and Black won (0-1, 45).
2) Michael-Tony (St. Joseph, 4/7/06): 7. d3 Bg4 8. 0-0 Nd4 9. c4 Qe6 10. Qa4+ c6 11. Nfg5!? Qg6 and Black won (0-1, 28)
3) Hermann-Charousek (Budapest, 1896): 7. Nc3 Qd8 8. 0-0 Bd6 9. d3 0-0 10. h3 f5 11. Re1 Bd7 12. Qe2 Qe8:

Black has a clear advantage, owning the center and controlling more space. 13. Be3 Qg6 14. Kh1 f4 15. Bd2 Nd4 16. Nxd4 exd4 17. Ne4 f3 18. gxf3 Bxh3 19. Rg1 Qh5 20. Rg5 Qh4 21. Kg1 Bh2+! 22. Kh1 (22. Kxh2 Bf1+) Bf1! 23. Qd1 (23. Qxf1 Bg3+) Be2! 0-1 (24. Qxe2 Bg3+ mates).
4) Bickenbach-Keres (Poznan, 1943): 7. Nc3 Qa5 (this seems more active than 7 ... Qd8) 8. d3 Bg4 9. Bd2 Nd4 10. Ne2!? Nxf3+ 11. gxf3 Qd5!:

The pin on the Pf3 wins material. 12. Nc3 Qxf3 13. Qxf3 Bxf3 14. Rg1 0-0-0 and Black won (0-1, 30).
5) Nielsen-Hammer (Helsingor, 2007): 7. Nc3 Qd8 8. d3 Bg4 9. h3 Bh5 10. g4 Bg6 11. Qe2 Bb4 12. Bd2 Qd6 13. 0-0-0 0-0-0:

Chances are even, yet again Black has more space. 14. Ne4 Bxd2+ 15. Rxd2 Qe6 16. Kb1 h5 17. g5 h4 18. Qe3 Bf5 19. Nc5 Qd5 20. Ne4 b6 21. Nc3 Qe6 22. Ne1 Nd4 23. Ng2 Qc6 24. f4 Rhe8 25. fxe5 Nxc2! 26. Qf2 (26. Rxc2 Bxd3; 26. Kxc2 Rxd3!) Nd4 27. Rc1 Nf3 28. Ne4? Nxd2+ 29. Qxd2 (29. Nxd2 Bxd3+) Qxe4! 0-1.
This section covered 6. Bd3 and 6. Bxd5 after the Fork Trick.
Next time we'll look at other options on Move 6. Please let me know if you find any typos or mistakes in this article. Keep studying! =) 10/19/2007
The universal question from juniors and students: "How can I get better at chess?" Sometimes the easy questions are the hardest, yet anyone can create a successful strategy for improvement, no matter what your present level. Here are some ideas to become stronger at chess:
1) PLAY. The first step is to play – play play play play play. This should be easy, because you already enjoy chess. Try to play serious games (taking notation, using clocks, touch move, no takebacks) on a regular basis. Your local chess club is a great place to find training games against quality opposition, and don't feel uneasy about recording the moves. (We'll cover that next.) The Internet features around-the-clock opportunity to play serious games at time controls from g/5 (blitz) up to 3-7 days/move (correspondence/slow chess). Free playing sites include the Free Internet Chess Server (FICS), ChessAnyTime and Yahoo for live play, or GameKnot and Queen Alice for correspondence. Note Internet chess carries the inherent drawback that your opponent might be using computer help, and you won't know for sure, yet it's still good practice for you. If you do play on the Internet, don't ever cheat, as you will never learn anything.
Many beginning players will improve dramatically just through frequent play. Of course, this will only take you so far, since at some point you have to understand why you lose. Moreover, one might easily overestimate their own ability until facing more experienced opposition. It can be an unpleasant surprise to visit a club or tournament packed with serious players who can exploit unsound tactics or risky strategy. This is the juncture where many enthusiasts drop out of competitive chess permanently, but you can and will improve if you just stick with it through this phase. You should aim for games with longer time controls if you want to improve, as blitz chess is typically won or lost based on blunders and oversights, or else it can degenerate into an unfair win/loss on time.
2) REVIEW. The analysis session between both players immediately following a game is called a post mortem. This practice is often overlooked or minimized, but reviewing your games with your opponent right afterwards is incredibly helpful. You can discuss opening play, alternate variations, missed tactics, quicker wins, drawing resources, all at your leisure with no time pressure. It's best to replay that game following your written scoresheet, thus you should record the moves during play instead of trying to reconstruct everything later. One word of caution: this is not the time to tell your opponent how lucky they are, or how bad they were, or any other confrontational posing. Even if they really were lucky during the game, do not say that. The post mortem should be a positive exchange of ideas for next time, with definite mutual benefit and no sour aftertaste. Be polite and gracious toward your opponent. And if they don't want to go over your game for whatever reason, then don't press the issue.
Another helpful way to review your game involves using a computer to analyze the moves on both sides. There is a small learning curve from a terminology standpoint (nodes, ply), also the clunky phrases plugged into the software can be jarring ("the Knight feels good on f4" & "Rxg8 doesn't get the bull off the ice" & such). But computers are extremely sharp at picking up missed tactics and finding quicker winning sequences. I have Fritz 7 which is very user friendly, but any engine you choose will quickly become indispensable to your improvement. To this end, don't feel obligated to find the latest, greatest, and most expensive product; just find one and use it.
3) ANNOTATE. After you have reviewed the game with your opponent, and ideally before you run it through an engine, write down your own comments and variations for your game, as thoroughly and completely as possible, and then add your annotations to the gamescore. Greater detail is always better, however this process takes some practice to limit stating the obvious ("White develops the Bishop" & "Black attacks the Queen" & such). Your first attempts might be quite shaky, but we all have to start somewhere. Ultimately your favorite efforts should go into a Best Games Collection that you keep in a notebook or else post on an Internet blog for future reference.
Botvinnik wrote, "It is vital to check one's analyses thoroughly, including those that have already been published." Indeed, World Champions from Steinitz to Anand have all strongly recommended that amateurs should annotate their own games as a crucial means to understand their own play and improve for next time. Note Alekhine, Botvinnik and Fischer were particularly outstanding annotators, mostly due to their blunt honesty and sincere attitude regarding mistakes, so studying their annotated games would be highly instructive. Remember that annotations could always be edited and corrected later, as sometimes an outside reviewer would find a suggestion or hole in your analysis.
4) STUDY. Botvinnik again: "To broaden one's chess outlook it is useful to study the game collections of the leading chess players. To improve one's accuracy of calculation, one should solve endgame studies and analyze games abounding in tactical ideas." One easy way to start would be finding reference games with the same opening as one of your games, to compare how a master handles their middlegame and endgame versus your example. Then you could cite that reference into your annotations for later. Naturally chess books contain a wealth of information, even though the opening theory becomes quickly dated, and there are several magazines devoted to chess. A serious student should visit their library or search the Internet before purchasing any books or magazines, as there is literally unlimited wordage to be found out there. The Exeter Chess Club is a popular Web site with lots of useful instruction at the student/junior level. I frequently visit chessgames.com which features a large database of master games along the ability to kibitz (post comments) on specific games within that database, plus other message boards on specific openings and famous players. As you find games and information, consider writing an article on an opening variation you like, or else create a tactics quiz, or cover an endgame subject. Whenever you read an article, you may learn a lot, but whenever you write an article, you will learn a ton.
Remember no study time is wasted if you're learning something. At the same time, try to concentrate your time on openings you play, common endgames, and solving puzzles. In my opinion, the five most common ways for beginners to win or lose is 1) tactics 2) tactics 3) tactics 4) tactics 5) missed tactics. So study tactics already. On the Internet, the Emrald Chess Tactics Server offers free timed puzzles to solve, so you can truly test yourself against the clock which is great practice. Like anything else, the more practice, the better you'll get. Beyond that, the more you know about tactics, the better your annotations will be, and thus the better player you'll become.
5) COACH. The best way to learn is to teach. Whatever your present level, you still know an immense amount about chess, and therefore you could use your knowledge to teach and instruct less experienced players. Showing up at chess club to play against a beginner and then reviewing that game with them is one form of coaching. Any school with a chess program would welcome your help and guidance, for as much time as you have to spare. And the age factor is irrelevant; the teacher is usually older than the student, but it could easily go the other way so both can learn together.
Don't put any pressure on yourself to develop structured teaching plans or detailed study schedules for students, although it does help to be systematic and organized. You could spend an hour reviewing the Ruy Lopez or the Sicilian or any other standard opening, sharing ideas and preferences and traps. Maybe you could study Rook and Pawn endgames together (a common area for improvement that we all need), or play through one classic game at length. Some folks create study groups to review the latest "Chess Life" cover to cover, going over games and content together. Another good idea is to present one of your games as a puzzle for your student to solve, and vice versa. The possibilities are truly endless.
Hopefully these guidelines will give you some ideas and inspiration to improve your own chess, and to help others improve as well. Good luck!
