The Italian Game begins 1.e4 e5 2.Nf3 Nc6 3.Bc4. Thisclass covers the Two Knights Defence with 3...Nf6 4.Ng5!Other fourth moves were discussed in the last magazine.

4. . . . Bc5!? (diagram 1)A daring move called the Traxler Counterattack. At first

sight, it looks like a mistake because it allows a captureon f7. But White must play very accurately to get anadvantage against this tricky gambit.The obvious 5.Nxf7? is too risky. The knight forks the

queen and rook, but White has a lot of problems to solveafter 5...Bxf2+! Here are some possibilities:

6.Kxf2 Nxe4+ 7.Ke3? Qe7!7.Ke2 Nd4+ 8.Kd3 b5!7.Kg1 Qh4

8.Qf3 Rf88.g3 Nxg3!

9.hxg3 Qxg3+9.Nxh8 d5 10.Qf3 Nf5!

6.Kf1 Qe7 7.Nxh8 d5!8.Qf3 Bh4!8.exd5 Nd4

The right way to deal with the Traxler is 5.Bxf7+! Then5...Kf8 blocks in the rook on h8. After 6.Bb3 d5 7.exd5 Nd48.Ne6+, White is great. So Black normally plays ...

5. . . . Ke76. Bb3!

Also good is 6.Bd5.

6. . . . Rf8Black develops the rook and

stops a fork by 7.Nf7.

7. 0 - 0 (diagram 2)

Now that the white king is castled, the danger of acounterattack is over. The book line goes 7...d6 8.Nc3Qe8 9.Nd5+ Kd8 10.c3! h6 11.d4 exd4 12.Nxf6 Rxf6 13.e5!White stands better.

Our next topic is the Fritz Variation, named for Germanplayer Alexander Fritz. After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf64.Ng5, Black continues with the usual 4...d5, instead of4...Bc5, and then 5.exd5 Nd4!? (diagram 3, next page).

Other options for Black are 5...Nxd5?, which allows theFried Liver Attack (covered in our previous class) and5...Na5!, the best move. We look at it later in this lesson.

Traxler Counterattack

Scholar’s Mate 139 98 Scholar’s Mate 139

If Black’s goal is to make a tactical mess, then the Fritzis the right defence. White can get the edge, but only bywalking along a tightrope of precise moves.

6. c3! (from diagram 3)The necessary first step. Other moves favour Black:

6.0-0? b5! 7.Bb3 h6 8.Nf3 Bg46.d6? Qxd6!

7.Nxf7? Qc6!8.0-0 Qxc4 9.Nxh8 Nxc28.Nxh8? Qxg2! 9.Rf1 Qe4+

9.Be2 Nf3#!7.Bxf7+ Ke7 8.Bb3 Nxb3

9.axb3 h6 10.Nf3 e4 11.Ng1 Kf76. . . . b5!

White has good play after 6...Nf5?! 7.d4 exd4 8.0-0!

7. Bf1!This surprising retreat is

White’s best choice. 7.Bd3? Bf5! 8.Bxf5 Nxf57.Bb3?! Nxb3 8.Qxb3 Qxd57.cxd4 bxc4 8.dxe5 Qxd5!

(9.exf6 Qxg5 or 9.Nf3 Nd7)7. . . . Nxd5!

Keeping things complicated. See diagram 4.

If Black retreats the knight on d4 with 7...Nf5, White getsan easy game by 8.Bxb5+ Bd79.Qa4.

8. Ne4!Things are less clear after:8.cxd4 Qxg5 9.Bxb5+ Kd8

10.Qf3 Bb7 11.0-0 Rb88.Nxf7 Kxf7 9.cxd4 exd4

10.Qf3+ Nf6!? 11.Qxa8 Bc5

8. . . . Qh4!9. Ng3 (diagram 5)

The position is still messy but White has the upper hand.Some sample lines:

9...Bb7 10.cxd4 0-0-0 11.Be2 Nf4 12.0-0 Bxg2

13.Bf3 Bxf1 14.Qxf19...Bg4!? 10.f3

10...Nf5 11.Bxb5+ Kd8 12.0-0 Bc5+ 13.d4 exd4 14.Ne4

10...e4! 11.cxd4 Bd6 12.Bxb5+ Kd8 13.0-0 exf3 14.Qb3!

Fritz Variation

Next up is the main line of the Two Knights Defence. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5

5. . . . Na5! (diagram 6)

Black sacks a pawn and attacks the bishop on c4. Whitecan guard the bishop by 6.d3 (hoping for 6...Nxd5? 7.Qf3).But Black gets good play with 6...h6! 7.Nf3 e4! 8.Qe2 Nxc49.dxc4 Bc5. So White usually plays:

6. Bb5+ c66...Bd7 7.Qe2 Be7 8.Nc3 0-0 9.0-0 is worse for Black.

7. dxc6 bxc6 (diagram 7)

Here White has two good options. The first is 8.Qf3, theBogoljubov Variation (diagram 8), named after a famousGerman grandmaster. The whitequeen pins the black c-pawn.(8...cxb5? 9.Qxa8)

Black offers another pawnthen with 8...Rb8! Taking it by9.Bxc6+ Nxc6 10.Qxc6+ Nd7!11.d3 Be7 gives Black veryactive play. A safer approachfor White is 9.Bd3 h6 10.Ne4,settling for one pawn.

White’s other option is:8. Be2 (diagram 9)

Now black gains time by attacking the white knight.

8. . . . h69. Nf3 e4!

10. Ne5 Bd6(diagram 10)

White can guard the knightwith f4 or d4. Both lead tosimilar positions after Blackcaptures en passant.

11.f4 exf3 12.Nxf3 0-0 13.0-011.d4 exd3 12.Nxd3 Qc7

13.b3 0-0 14.Bb2 Ne413.h3 0-0 14.0-0 Bf5 15.Nd2

In each case, the game is balanced. Black has betterdevelopment. White has an extra pawn. This is a typical situation in the Two Knights Defence.

Would you rather have the pawn or the active pieces?

Hello, friends. We’ve got a fun show for youtonight. A famous chess champion is joining us.

That’s right, Marley. Our special guest is the“Greatest Of All Time”.

But, Mort, this is a goat, not the G.O.A.T.

Well, maybe he’s a great goat!

I don’t think so, Mort. He looks pretty ordinaryto me. Can he even play chess?

Hard to say, Marley. All he does is eat stuff.

ADOLF ANDERSSEN(1818 - 1879)

One of the great masters of attack, this Germanprofessor of mathematics was considered thebest player in the world after he won the firstinternational tournament at London in 1851.

“Chess is the gymnasium of the mind.”

ANDERSSEN OPENING 1.a3He was famous for aggressive play in the King's Gambitand Italian Game, but the opening that bears his nameis a way for White to give the "first move" to Black.

Anderssen was fearsome at the chessboard,but was admired for his kindness and goodmanners away from it. Two of his most brilliantvictories are known as the "Evergreen Game"and the "Immortal Game".

However, it’s not time to resign. White can score half apoint with the queen sacrifice 1.Qg7+!, forcing a “perp”.1...Kxg7 2.Rxf7+ Kg8 (2...Kh6? 3.Rxh7#) 3.Rg7+ Kh84.Rxh7+ Kg8 5.Rhg7+!

IN LIKE A LION,OUT LIKE A LAMBIN LIKE A LION,OUT LIKE A LAMB

It was the last day of February, the coldest month ofthe year. Time again for the annual match between thelions and the lambs.

There was a chill in the air, and dark clouds on thehorizon, but that didn’t stop the crowd from filling thestadium. Nobody wanted to miss the big event.

Banners were flying and tails were wagging, as thecontestants took the field. One lamb, one lion. Theywould play a single game to decide everything. “A fleece as white as snow” versus “the king of beasts”.

It promised to be a classic battle. The lions have always dominated their opponents. But

like a patch of blue in a stormy sky, the sheep still keepa glimmer of hope in their hearts. Maybe this will be theyear they win. Maybe this will be their time to shine.

It all depends on one little lamb. Would she be a herotoday? Or just another lamb to slaughter?

White TTTT HHHH EEEE LLLL AAAA MMMM BBBBBlack TTTTHHHHEEEE LLLLIIIIOOOONNNN

1. e4With a confident smile anda nod to her fans, the lambis off to an excellent start.

1. . . . d5The Scandinavian Defence.

The lion raised a paw androared as he pushed hispawn into the centre.

2. exd5 Nf6Black plans to take backon d5 with the knight. Morecommon is 2...Qxd5 3.Nc3Qa5 (or 3...Qd6).

3. d4If White tries to keep the

pawn by 3.c4, Black playsthe gambit 3...c6! 4.dxc6?!(4.d4 cxd5) 4...Nxc6 5.Nf3e5 with advantage to Black.Another line goes 3.Bb5+

Bd7 4.Bc4 when Black canchoose between 4...Bg4 or4...b5!? 5.Bb3 a5.

However, the advance 6.d5is not as good as it looks.White should settle for aslight advantage with 6.a3Na6 7.d5 Nc5 8.Qd1. (Not8.Qb5?, which would losethe queen following 8...e69.dxc6 b6! and 10...a6.)

6. . . . b5! This pawn sacrifice was areal surprise to the lamb,and to the spectators.

7. Qxb5Keeping the knight on c6

pinned. On other moves,black saves the knight.

The game is level after7.cxb5 Nd4 8.Na3 (8.Qxb4?Nc2+) 8...e6 9.dxe6 Bxe6or 7.Qd1 Nd4! 8.Na3 e5.

7. . . . Nc2+ Forking king and rook. Thec2 square is no longerguarded by the queen.

8. Kd1 Bd7!Much better than 8...Nxa19.Qxc6+ Bd7 10.Qa6, withan unclear position.

9. dxc69.Kxc2 loses the queen tothe knight fork 10...Nd4+.

4. c4

The lamb takes charge ofthe centre and drives theblack knight away. Shewas selected to representthe sheep because of heraggressive qualities.On thechessboard, that is!

4. . . . Nb4Usually black retreats herewith 4...Nb6, but this lionhas his own aggressiveideas.

5. Qa4+White is playing to win theblack knight. A simple wayto get the better positionwas 5.a3 N4c6 6.Be3.

5. . . . N8c6

6. d5 ?! The sheep all jumped outof their seats and cheeredlike crazy when this movewas made. HooRaH!

All the lions stood and roared as the band played theirvictory song. They had won again.

The sheep, saddened by another defeat, hung theirheads proudly. It had been a good game.

In the distance, lightning flashed across the cloudy sky.Thunder rumbled, the cold winds blew, and snow beganto fall. The blizzard had arrived.

It was the worst storm of the year, and the start to along week of freezing days and frigid nights.

52 Scholar’s Mate 139

It's easy. The board has 8 filesand 8 ranks. Files are the rowsof squares that go up and down.Each one is named by a smallletter. Ranks are rows that gosideways. Each one is namedby a number.Every square also has a name.

The first part is its file and thesecond part is its rank. In thisdiagram, a white pawn movedto e4 and a black pawn to e5.

When moves are written down,the first capital letter shows thepiece which moves. Q is queen.B is bishop. R is rook. N is usedfor knight because the king is K.If there is no capital letter, thatmeans a pawn moves.

Next is the square that thepiece moves to. Bc4 says that abishop moves to the square c4.When a piece is captured, an xis put before the square. Qxf7means a queen takes on f7.

If a pawn captures, the letterof the file it starts on is givenfirst, then an x followed by thesquare it takes on. exd5 says apawn on the e-file captures onthe square d5.

When two pieces of the samekind can go to the same spot,another letter is put after thepiece to show what file it camefrom. Rae1 tells us that a rookon the a-file moves to e1.

If the pieces that can move tothe same spot are on the samefile, then their rank number isadded. N6e4 means the knighton the 6th rank moves to e4.

Here are some special symbols:+ check# checkmate

e. p. en passantO - O castles kingside

O - O - O castles queenside1 - 0 white wins0 - 1 black wins

½ - ½ draw! excellent move? mistake!? cool move?! weird (weak) move
