1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.e3 c5 5.Nf3 Nc6 6.a3 {A good waiting move. The idea is to move White's light squared bishop to c4 in one move instead of two in the event Black plays 6...dxc4. White also threatens to capture at c5 and then play b4 and Bb2. 6.Bd3 dxc4 7.Bxc4 when White's bishop has moved two times to get to c4.} dxc4 7.Bxc4 cxd4 8.exd4 {White has open lines as compensation for his isolated d-pawn.} Be7 9.O-O O-O 10.Be3 {This is not the best move since the bishop on e3 acts as a big pawn while it blocks the e-file for White's major pieces. 10.Re1 would give White's pieces more activity.} Bd7 {10...b6 With the idea of 11...Bb7 would keep the d-file open thus putting greater pressure on the isolated d-pawn.} 11.Qd3 {11.d5 would lead to massive exchanges after 11...exd5 12.Nxd5 Nxd5 13.Bxd5} Rc8 12.Rac1 Qa5 13.Ba2 Rfd8 14.Rfe1 Be8 {Black clears the d-file so his rook can pressure the isolated d-pawn.} 15.Bb1 {White forms a battery on the b1-h7 diagonal.} g6 {This move not only stops any attack White might get against the h7 square, but it also allows Black' dark squared bishop to attack the d-pawn from the g7 square.} 16.Qe2 Bf8 17.Red1 Bg7 18.Ba2 Ne7 19.Qd2 Qa6 {19...Bc6 20.Nd5 Qxd2 21.Nxe7+ Kf8 22.Nxg6+ hxg6 23.Nxd2 would leave White a pawn ahead.} 20.Bg5 Nf5 {Black has a big advantage due to his pressure on White's isolated d-pawn.} 21.g4 {This weakening of White's kingside is a mistake even if the knight had to go backwards. 21.Be3 With the idea of activating the king knight with 22.Ne5 would be a better idea.} Nxd4 22.Nxd4 e5 23.Nd5 Rxc1 24.Qxc1 {24.Rxc1 exd4 25.Nxf6+ Bxf6 26.Bxf6 Qxf6 would give Black a winning advantage due to his extra pawn and White's exposed king.} exd4 25.Rxd4 Nxd5 26.Rxd5 {Not 26.Bxd8 Bxd4 27.Bxd5 Qe2 when Black has an attack on three White pawns b, f and g.} Rxd5 27.Bxd5 {White's bishops are clearly more active, but there is a significant weakness on the kingside.} Qe2 28.h3 {The h-pawn no longer enjoys the protection of the king.} h6 {Black cannot capture this pawn.} 29.Bc4 {29.Bxh6 Bxh6 30.Qxh6 Qd1+ 31.Kh2 Qxd5} Qf3 30.Qe3 Qd1+ 31.Kh2 Bc6 {31...hxg5 32.Qxe8+ Kh7 33.Bxf7} 32.Be7 Be5+ 33.f4 {Now White's king is even more exposed, and all of a sudden the Black bishops are more active than the White ones. Now Black has a winning sacrifice. Try to find it yourself.} Bxf4+ 34.Qxf4 Qh1+ 35.Kg3 Qg1+ {White resigned, since the only legal move allows a crushing fork:} 36.Kh4 Qe1+ 37.Qg3 Qxe7+ 38.g5 Qe4+ 39.Qg4 Qe1+ 40.Qg3 hxg5+ 41.Kg4 Qe4+ 42.Kxg5 Qxc4 43.Qb8+ Kh7   0-1

1.e4 e5 2.f4 exf4 3.¤f3 g5 4.h4 g4 5.¤e5

This is known as the Kieseritzky variation in the King's gambit where White's idea is to put immediate pressure on Black's f7 square.

5...¤f6 6.¥c4 d5

Black must stop White from coming in on the f7 square.

7.exd5 ¥d6

7...Bg7 preparing to castle while adding protection to Black's kingside should be preferred.

8.d4 ¤h5 9.¤c3 ¥f5

9...O-O removing the king from the center would have been a better plan.

10.¤e2 ¥xe5 11.dxe5 f3 12.gxf3 gxf3 13.¥g5 f6

13...fxe2 14.Qxe2 White has a double attack on Black's queen and knight.

14.exf6 £d6

14...fxe2 15.Qxe2+ Kf8 would allow White a mating attack.

15.£d4 fxe2 16.¥xe2 £g3+ 17.¢d2 O-O

Black's king will come under fire since he has just castled onto the open g- file.

18.¦ag1

Black resigned since after his queen moves, the open g-file would win the game for White. 18. Rag1 Black resigned due to White's mating attack down the open g-file.

Anderssen vs  Kieseritzky

1.e4

Known as the "Immortal Game" this magnificent example of Adolf Anderssen's combinative powers is still considered one of the best games of all time.

1...e5 2.f4 exf4 3.¥c4 £h4+ 4.¢f1 b5

The Bryan Counter-Gam bit where Black wishes to draw the bishop away from the a2-g8 diagonal.

5.¥xb5 ¤f6 6.¤f3 £h6

The Black queen proves to be out of play here. Better was 6...Qh5.

7.d3 ¤h5

7...g5 was a more natural way to defend the f-pawn.

8.¤h4

8.Kg1 would stop Black's threat of Ng3+ winning the exchange. However, White would now drop a piece instead.

8...£g5 9.¤f5 c6

9...g6 10.h4 Qf6 11.Nc3 gxf5 12.Qxh5 would give White the lead in development.

10.g4 ¤f6 11.¦g1

This piece sacrifice pursues White's agressive policy started with 8.Nh4. The important d5-square will now become available.

11...cxb5 12.h4 £g6

The queen is a useless bystander now.

13.h5 £g5 14.£f3

Threatens to trap the Black queen with 15.Bxf4.

14...¤g8

So Black is forced to retreat to the home square.

15.¥xf4 £f6 16.¤c3

Although White has only two pawns for a piece he has a winning position due to his large lead in development. Black's pieces, with the exception of the queen and the b-pawn, are all on their original squares.

16...¥c5 17.¤d5

This introduces a double rook sacrifice, where White will give up both of his rooks, even though he is already a piece down.

17...£xb2 18.¥d6

Thus begins the "Immortal Sacrifice".

18...£xa1+

18...Bxd6 19.Nxd6+ Kd8 20.Nxf7+ Ke8 when White would have a forced mate in two.

19.¢e2 ¥xg1

The best defense, as noted by Steinitz, was 19...Qb2, but fortunately for posterity Kieseritzky didn't figure that out. 19...Qxg1 would again allow White a forced mate.

20.e5

By blocking the queen off the protection of his g-pawn. White is threatening to mate in two with 21.Nxg7+ Kd8 22.Bc7 mate.

20...¤a6

Black covers the c7 square from White's dark squared bishop. However, just when you think Black might defend, Anderssen explodes the position with yet another brilliant line.

21.¤xg7+ ¢d8 22.£f6+

By sacrificing the queen White has mate next move.

22...¤xf6

The only move.

23.¥e7#

A forced mate by three minor pieces while Black still has most of his pieces on the board. Truly a magnificent game...The Immortal Game.

This is an example of a rook and pawn endgame, also just called a rook endgame . Even though White has more pawns, they are scattered and isolated. The doubled pawns are particularly weak, so Black actually has the advantage.

42.¦d8 ¦d3 43.d5 f4 44.d6 ¦d2+ 45.¢f1 ¢f7

White's pawn has advanced down the board, but the Black king takes an active role in the defense.

46.h5 e3 47.h6 f3

Now Black has established mating net. The threat is Rd1 mate. White actually resigned, because the only escape from mate is to move the king away from the pawns, but then Black gets a queen:

1.e4 e5 2.c3 ¤f6 3.d4 ¤xe4 4.dxe5 ¥c5

The opening has turned into a very sharp position, and now White turns up the heat!

5.£g4 ¤xf2 6.£xg7 ¦f8

White's invasion is more dangerous than Black's.

7.¥g5 f6 8.exf6 d5 9.¥e2 ¥g4

This minor nuisance can be dealt with in an obvious way.

10.¥xg4 ¤xg4 11.f7+ ¦xf7 12.£xf7+ ¢xf7 13.¥xd8 ¤f2

Black has made far too many moves with this knight, which now moves into a position from which it will never escape.

14.¥h4 ¤xh1 15.¤f3 ¤c6 16.¤bd2 ¦g8 17.¢f1 d4 18.cxd4 ¤xd4 19.¤xd4 ¥xd4 20.¤f3 ¥b6 21.¦e1 h6 22.¦e7+ ¢f8 23.¤e5 ¦g7 24.¤d7+ ¢g8 25.¦xg7+ ¢xg7 26.¤xb6 axb6

White wins because Black's knight is trapped. Notice that this would be true even if the White king were far away, since the bishop on h4 controls all of the escape squares for the knight.

This is another game against Royalty (see also Morphy-Lyttleton). The present game is better known, having been played at the Paris Opera during a performance of the Barber of Seville. Talk about distractions!

1...e5 2.¤f3 d6 3.d4 ¥g4 4.dxe5 ¥xf3 5.£xf3 dxe5 6.¥c4 ¤f6 7.£b3 £e7 8.¤c3

Given the  circumstances of the game, Morphy just didn't feel like capturing the pawn at b7. That would have taken the fun out of the game!

8...c6 9.¥g5 b5 10.¤xb5

That's more like it! Morphy sacrifices a knight for the b-pawn instead of capturing it for free at his 8th turn.

10...cxb5 11.¥xb5+ ¤bd7 12.O-O-O ¦d8

Both knights are pinned, and Morphy now trades one pin for another.

13.¦xd7 ¦xd7 14.¦d1 £e6 15.¥xd7+ ¤xd7

Black has an extra piece, but White checkmates in two moves. If you can't find Morphy's brilliant finish on your own, continue on and let Gambit show you. Either way, it is a pleasant sight!

[White "Morphy"]
[Black "Carr"]
[Result "1-0"]
[PlyCount "49"]

1.e4 h6 2.d4 a5

A time-honored strategy when playing against a blindfolded opponent is to adopt an obscure, and often bad, opening, in the hope of creating confusion. It is a bad idea, and rarely works!

3.¥d3 b6 4.¤e2 e6 5.O-O ¥a6 6.c4 ¤f6 7.e5 ¤h7 8.f4

White has superior development and complete domination of the center. Morphy hardly seems to be confused by his opponent's ridiculous opening strategy.

8...¥e7 9.¤g3 d5 10.£g4 O-O

This is knows as "castling into it".

11.¤h5

Suppose Black plays 11... g6 here. How could you bring the game to a rapid close.

11...g5

Black has little choice but to create this major weakness on the kingside.

12.fxg5 hxg5 13.¥xh7+ ¢h8

13...Kxh7 14.Nf6+ Bxf6 15.Rxf6 and checkmate will follow shortly.

14.¤f6 dxc4 15.¥c2

Everyone at Electronic Arts hopes that you will never, ever, be in such dire straits as Black is here, even if your opponent is blindfolded! Black now uses a combination to exchange queens, but loses material.

15...£xd4+ 16.£xd4 ¥c5 17.£xc5 bxc5 18.¥xg5

Black's position cannot be said to be much improved. Fortunately, Morphy does not allow Mr. Carr to live long enough to suffer greatly.

18...¤c6 19.¦f3 ¢g7

Now Morphy forces checkmate in 6 moves.

1.e4 e5

Morphy's opponent is not just an ordinary citizen, but a British Lord and President of the British Chess Association. All of which is of no use when seated at the chessboard against Morphy, even when Morphy is blindfolded!

2.f4 exf4 3.¤f3 g5 4.h4 g4 5.¤e5

This position was frequently seen in games played in the 19th century.

5...d6 6.¤xg4 ¥e7

Black gains time by attacking the weak pawn at h4.

7.d4

White occupies the center, achieving one of the primary objectives of the opening.

7...¥xh4+ 8.¤f2 ¥xf2+

It might have been nice to maintain this pin a bit longer, but Black wants to be able to bring the knight at g8 into the game.

9.¢xf2 ¤f6 10.¤c3 £e7 11.¥xf4 ¤xe4+ 12.¤xe4 £xe4 13.¥b5+

A powerful move, threatening a nasty pin with Re1.

13...¢f8

13...c6 14.Re1

14.¥h6+ ¢g8 15.¦h5

White is closing in for the kill. The king is trapped along the back rank, so if White can get a rook or queen to the e- file and then to e8, the game ends.

15...¥f5 16.£d2

The threat is Re1.

16...¥g6 17.¦e1

The move that was set-up by 13.Bb5+ finishes the game, as if the queen moves, Re8+ mates.

1.e4 e5 2.¤f3 ¤c6 3.¥c4 ¤f6 4.d4 exd4 5.¤g5 d5 6.exd5 ¤xd5

This loses, as Black's king becomes too exposed.

7.O-O ¥e7 8.¤xf7

Now Black's king will get dragged to e6 where it will shortly die of exposure.

8...¢xf7 9.£f3+ ¢e6 10.¤c3

This beautiful sacrifice has two purposes. First, White gets ready to bring his queen rook into the fight, and second, Black's d- pawn is drawn away from its post keeping the d-file closed. Black can't decline, since d5 is attacked.

10...dxc3 11.¦e1+ ¤e5 12.¥f4 ¥f6 13.¥xe5 ¥xe5 14.¦xe5+

Now it will be White's rook, queen and bishop against Black's bare king, not a fair fight.

14...¢xe5 15.¦e1+ ¢d4 16.¥xd5

Black's king has nowhere to run to.

16...¦e8 17.£d3+ ¢c5 18.b4+

1.e4 d5 2.exd5 £xd5 3.¤c3 £a5 4.d4 e5

A mistake since opening up the position will favor the side who is better developed and in this case it's to White's advantage. 4...Nf6

5.dxe5 £xe5+ 6.¥e2 ¥b4 7.¤f3

White shows a deep understanding of the position. By giving up a pawn he will gain the advantage of having his pieces developed.

7...¥xc3+ 8.bxc3 £xc3+ 9.¥d2 £c5 10.¦b1

White has developed four pieces to Black's one due to the sacrificed pawn.

10...¤c6 11.O-O ¤f6 12.¥f4 O-O

12...Nd5 would allow White to win a piece.

13.¥xc7

White stands much better since he has regained his sacrificed pawn while keeping his lead in development.

13...¤d4 14.£xd4 £xc7

14...Qxc2 With the idea of attacking both bishops would backfire after 15.Bc4 when White hangs on to his extra piece.

15.¥d3 ¥g4 16.¤g5 ¦fd8

17.Bxh7+ Nxh7 18.Qxg4 Nxg5 19.Qxg5 Qxc2 20.Rxb7 Qxa2 allows Black to keep the material even.

18.¦fe1

White has a big advantage due to his better development.

18...a5 19.£e7 £xe7

19...Rd7 Here White has a forced mate in two.

20.¦xe7

The exchange of queens has increased White's advantage due to his rook being on the seventh rank.

20...¤d5

20...Rf8 21.Bc4 would force Black to part with his f-pawn.

21.¥xh7+

21.Rxf7 h6 when Black would win material because of the double attack on both the White rook on f7 and the knight on g5.

21...¢h8 22.¦xf7 ¤c3 23.¦e1 ¤xa2 24.¦f4

With the idea of catching the Black king in a mating net after a future Rh4.

24...¦a6 25.¥d3

Black resigned since the further loss of material is unavoidable. White threatens 25.Nf7+ winning the rook on e8 and 25.Bxa6.

Better is 3.c3 at once.

Suppose White takes the pawn at e5.

4.¥c4 ¥e7 5.c3 d6 6.£b3

There isn't anything to be done about the pawn at f7, because 6...Nh6 will be met by 7.Bxh6.

The development of the queen knight in this position was a Morphy specialty. 9. d5 was favored by another great attacking player: Adolf Anderssen.

Black's idea is to put pressure on the White d-pawn. However, this is a mistake since the Black queen will be subject to attack on f6.

26.£e8+ ¦f8 27.¥xd5+ £f7 28.¥xf7+ ¦xf7 29.£e5 ¦f6 30.h6

Black resigned since he has no compensation for his lost material.

1.e4 e5 2.¤f3 ¤c6 3.¥c4 ¥c5 4.b4

The Evans Gambit where White sacrifices a pawn for rapid development.

4...¥xb4 5.c3 ¥c5

This move allows White to play d4 with gain of a tempo on the dark squared bishop. 5...Ba5 From a5 the dark squared bishop doesn't have to worry about losing a tempo when White advances pawn to d4.

6.O-O d6 7.d4 exd4

7...Bb6 is another possibility.

8.cxd4 ¥b6 9.¥b2

Since the bisho p moves again in a few moves 9.Nc3 should be preferred. 9.Nc3 Bg4 10.Bb5 Kf8 11.Be3 would give White compensation for his pawn.

9...¤f6 10.e5

This move  is inconsistent with White's previous Bb2 since e5 didn't need any preparation. 10.d5

10...dxe5 11.¥a3 ¥e6 12.¤bd2 e4

Black already has a won game as White has no compensation for his lost material.

13.¦e1

Although this piece sacrifice does not work White decided to go down fighting.

13...exf3 14.£b3 £xd4

Black has his own attack on White's f2 square.

15.¤xf3

15.Bxe6 would allow Black a mate in two.

15...£xf2+ 16.¢h1 O-O-O

Now that the Black king has reached safety White could resign at any time.

17.¦xe6 fxe6 18.¦f1 ¤e4

Black ends the game with a little combination based on White's weakened back rank.

19.¦xf2 ¤xf2+ 20.¢g1 ¦d1+

Takes advantage of White's weak back rank.

21.£xd1

White resigned because of his material deficit.

1.d4 d5 2.c4 e6 3.¤c3 ¤f6 4.e3 c5 5.¤f3 ¤c6 6.a3

A good waiting move. The idea is to move White's light squared bishop to c4 in one move instead of two in the event Black plays 6...dxc4. White also threatens to capture at c5 and then play b4 and Bb2. 6.Bd3 dxc4 7.Bxc4 when White's bishop has moved two times to get to c4.

6...dxc4 7.¥xc4 cxd4 8.exd4

White has open lines as compensation for his isolated d-pawn.

8...¥e7 9.O-O O-O 10.¥e3

This is not the best move since the bishop on e3 acts as a big pawn while it blocks the e-file for White's major pieces. 10.Re1 would give White's pieces more activity.

10...¥d7

10...b6 With the idea of 11...Bb7 would keep the d-file open thus putting greater pressure on the isolated d-pawn.

11.£d3

11.d5 would lead to massive exchanges after 11...exd5 12.Nxd5 Nxd5 13.Bxd5

11...¦c8 12.¦ac1 £a5 13.¥a2 ¦fd8 14.¦fe1 ¥e8

Black clears the d-file so his rook can pressure the isolated d-pawn.

15.¥b1

White forms a battery on the b1-h7 diagonal.

15...g6

This move not only stops any attack White might get against the h7 square, but it also allows Black' dark squared bishop to attack the d-pawn from the g7 square.

16.£e2 ¥f8 17.¦ed1 ¥g7 18.¥a2 ¤e7 19.£d2 £a6

19...Bc6 20.Nd5 Qxd2 21.Nxe7+ Kf8 22.Nxg6+ hxg6 23.Nxd2 would leave White a pawn ahead.

20.¥g5 ¤f5

Black has a big advantage due to his pressure on White's isolated d-pawn.

21.g4

This weakening of White's kingside is a mistake even if the knight had to go backwards. 21.Be3 With the idea of activating the king knight with 22.Ne5 would be a better idea.

21...¤xd4 22.¤xd4 e5 23.¤d5 ¦xc1 24.£xc1

24.Rxc1 exd4 25.Nxf6+ Bxf6 26.Bxf6 Qxf6 would give Black a winning advantage due to his extra pawn and White's exposed king.

24...exd4 25.¦xd4 ¤xd5 26.¦xd5

Not 26.Bxd8 Bxd4 27.Bxd5 Qe2 when Black has an attack on three White pawns b, f and g.

26...¦xd5 27.¥xd5

White's bishops are clearly more active, but there is a significant weakness on the kingside.

27...£e2 28.h3

The h-pawn no longer enjoys the protection of the king.

28...h6

Black cannot capture this pawn.

29.¥c4

29.Bxh6 Bxh6 30.Qxh6 Qd1+ 31.Kh2 Qxd5

29...£f3 30.£e3 £d1+ 31.¢h2 ¥c6

31...hxg5 32.Qxe8+ Kh7 33.Bxf7

32.¥e7 ¥e5+ 33.f4

Now White's king is even more exposed, and all of a sudden the Black bishops are more active than the White ones. Now Black has a winning sacrifice. Try to find it yourself.

33...¥xf4+ 34.£xf4 £h1+ 35.¢g3 £g1+

White resigned, since the only legal move allows a crushing fork:

36.¢h4 £e1+ 37.£g3 £xe7+ 38.g5 £e4+ 39.£g4 £e1+ 40.£g3 hxg5+ 41.¢g4 £e4+ 42.¢xg5 £xc4 43.£b8+ ¢h7 0-1

1.f4 d5 2.e3 ¤f6 3.b3 e6 4.¥b2 ¥e7 5.¥d3 b6 6.¤f3 ¥b7 7.¤c3 ¤bd7 8.O-O O-O 9.¤e2 c5 10.¤g3 £c7 11.¤e5 ¤xe5 12.¥xe5

Just compare the relative activity of the bishops! Black is already in serious trouble.

12...£c6 13.£e2 a6

White has completed development and is ready to attack. The position of the rook at a1 cannot be improved, for the moment. Lasker starts by eliminating one of the few defenders of the Black king. But he doesn't part with the Be5.

14.¤h5 ¤xh5

White could simply recapture at h5 with a strong attack, but by sacrificing a piece the momentum is greatly increased.

15.¥xh7+ ¢xh7 16.£xh5+ ¢g8

Now White might like to transfer a rook to the h-file, but this is too slow, because Black is ready to play d5-d4 and threaten mate at g2. Then he could sacrifice some material in return and stay in the game.

17.¥xg7

A brilliant move which threatens mate at h8.

17...¢xg7 18.£g4+ ¢h7

Now the queen guards g2 and White can threaten the sideways equivalent of a back rank mate.

19.¦f3 e5

The only defense. Now the Black queen can come to h6.

20.¦h3+ £h6 21.¦xh6+ ¢xh6 22.£d7

This wins one of the bishops, and the game now is decisively in White's favor.

22...¥f6 23.£xb7 ¢g7 24.¦f1 ¦ab8 25.£d7 ¦fd8 26.£g4+ ¢f8 27.fxe5 ¥g7

27...Bxe5 28.Qh5! f6 29.Qxe5 shows another method of exploiting the pin on the f-file.

28.e6 ¦b7 29.£g6

White exploits the pin in the maximally efficient way.

29...f6 30.¦xf6+ ¥xf6 31.£xf6+ ¢e8 32.£h8+ ¢e7 33.£g7+

Now the rook at b7 falls, so Black gives up.
