[center]Epine Dorsal: Horseman Defense (Janisch Opening/Monte Carlo Variation)[/center][center]Position after [/center]

• This is the Monte Carlo Variation of the Janisch Opening. It was first played in London, 1851 by Anderssen against Löwenthal, but was seldom seen over the next half century. It made a steady appearance at a series of international tournaments held in Monte Carlo in the early twentieth century. The debut is also called the Nimzovich Attack, but JR Opening Catalog doesn't like to use the same name for multiple ideas and we will leave the name Nimzovich with ideas of playing Black's King's Bishop to b4 and pinning White's Knight at c3.
• Properly speaking, the Janisch is the variation covering 1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.d4 d5 6.Bd3 Be7 7.O-O Nc6 8.c4, while what we call the Janisch (1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.d4) is called the Classical Petroff. However, we don't like to overuse the word Classical, either.

• [font color="darkorchid"]17.Kb1 d4 18.Bxd4 Bxd4 19.b4 Rxe1+ 20.Rxe1 Qxh5[/font] remains equal.

18.a3

• If [font color="red"]18.Qd1 Qa5 19.Kb1[/font] then:
• If [font color="red"]19...Nc5 20.Bxc5 Qxc5[/font] then:

[center]WHITE: Hikaru Nakamura[/center][center]Position after 20.Bd3f5[/center]

20...Na4!

• Hit 'em where they ain't. --Ted Williams
• That's baseball, but it applies in chess as well. Black strikes at the queenside where White has no defenders and gains more freedom.
• If [font color="red"]20...Ne4?! 21.Bxe4! Rxe4 22.f3 Ra4 23.Bd4[/font] then:
• [font color="red"]23...Bxd4 24.cxd4 c5 25.Re7 Rxd4 26.Qe2 Rxf4[/font] is equal.
• [font color="darkred"]23...Qd8 24.Qd2 b5 25.Be5 Qe7 26.Kb1[/font] is equal.

21.Qd3 Nc5?!

• Black could have sacrificed on c3 here, but instead chases the Queen.
• If [font color="red"]21...Nxc3! 22.Bd2 d4 23.Bh7+ Kh8[/font] then:
• [font color="red"]24.Be4 Qc5 25.Bf3[/font] gives Black a trementous position.
• The theme of the sacrifice at c3 comes up often in the next dozen or so moves.
• If [font color="darkred"]24.bxc3?[/font] then [font color="darkred"]24...dxc3 25.Be3 Rad8![/font] leaves White no time to save the Queen on account of [font color="darkred"]26.Qe2 Qxa3+ 27.Kb1 Qb2#.[/font]

22.Qd1 Qb5!?

• Why doesn't Black just play 22...Na4 and try to get it right the second time?

23.Qe2!

• White dodges a bullet.

23...Qa4

• Accepting the invitation to exchange Queens is no better.
• If [font color="red"]23...Qxe2 24.Rxe2 Ne4 25.Rhe1 Nd6 26.Bg4 Re4[/font] gives Black only a small advantage in space.

24.Qd1!?

• White should leaves his Queen in contact with the weak pawn at c3.
• If [font color="red"]24.Qd2! Ne4 25.Bxe4 dxe4 26.Qe2 Rad8 27.Rd1[/font] is equal.

24...Ne4!?

• Black again contemplates the possibility of sacrificing at c3.
• If [font color="red"]24...Rad8![/font] then:
• [font color="red"]25.Bd4 Ne4 26.Rhg1 Kf8 27.f3 Bxd4 28.cxd4 Nd6[/font] gives Black stronger pawns and active pieces.
• [font color="darkred"]25.Bxc5?! Qxf4+! 26.Kb1 Qxf5 27.Rxe8+ Rxe8 28.Bxa7 Re4[/font] gives Black more freedom; White has the advantage in space, but cannot bring more force to the kingside fast enough. Speed, as it other sports, is an important element of chess.

25.Bxe4?!

• White allows Black a free hand in the center.
• If [font color="red"]25.Qd3[/font] (again, the c3 pawn needs to be overprotected) then:
• [font color="red"]25...Rad8 26.Bxe4 dxe4 27.Qe2 Qa5 28.Rhg1 Rd5 29.Rd1 Red8[/font] gives Black a small advantage in space.
• [font color="darkred"]25...Nd6!? 26.Rhg1 Nxf5 27.Qxf5 Re6 28.Rd1 Qc4[/font] gives Black a small advantage in space.

25...Rxe4!

• Black takes a fair advantage in space.

26.Rhg1 Rae8 27.Rg3?!

• White prepares to double the Rooks at the g-file, hoping for some counterplay.
• [font color="red"]27.Kb1 b6 28.Qd3 Qc4 29.Rd1 Qxd3 30.cxd3 R4e7[/font] continues to give Black a fair advantage.

[center]BLACK: Anish Giri[/center]

[center][/center]

[center]WHITE: Hikaru Nakamura[/center][center]Position after 27.Rg1g3[/center]

27...Kh8!

• This is an excellent example of a prophylactic move. Black continues to put pressure on the c-pawn and has power in the e-file.

28.Reg1 Qc4 29.Kb1 c5 30.Qd3!?

• It's too late for this now.
• If [font color="red"]30.Qf3! Qb5 31.Qg2[/font] then:
• [font color="red"]31...Rg8 32.Bc1 Qd7 33.Rd3 Qf5 34.f3 Re7[/font] continues to give Black a fair advantage in space.
• White is threatening [font color="darkred"]32.Rxg7 Bg5 33.Rxg5 hxg5 34.Qxg5[/font] with to follow soon.

30...b6!

• Black reinforces his kingside before taking specific measures.

31.Qxc4?!

• Even the exchange of Queens provides no relief.
• [font color="red"]31.Rd1 Qxd3 32.cxd3 R4e7 33.d4 c4 34.Rdg1 Re4[/font] continues to give Black a fair advantage in space.

[
31...Rxc4!

• Black again threatens to sacrifice on c3, which would be devastating even without Queens on the board.

32.Rd1?!

• The threat is idle. Taking on d4 would only make Whit vulnerable on the back rank.
• If [font color="red"]32.Bd2 Rce4 33.Rd3 Rd8 34.Kc1 Kh7[/font] gives BLack a better center, command of the e-file and stronger pawns.

32...d4!

• White's Bishop goes reeling back.

33.cxd4 cxd4 34.b3?

• White has been teetering since his 30th move, but now the game slips beyond hope.
• Better is [font color="red"]34.Bd2 Re2 35.Rf3 Rc5 36.f5 Kh7 37.c3 Rc4[/font] when Black has a pair of active Rooks., but it will take more work to break through White's defense.

[center]WHITE: Hikaru Nakamura[/center][center]Position after 34.b2b3[/center]

34...dxe3!!

• This is the right way to sacrifice the exchange.
• [font color="red"]34...Rxe3?[/font] is the wrong way to sacrifice the exchange; White wins after [font color="red"]35.fxe3! Rc3 36.Rd3 Rxd3 37.cxd3 dxe3 38.Rxe3[/font] when Black has no compensation.

35.bxc4 exf2 36.Rf3 Re1

• If [font color="red"]36...Bh4[/font] then:
• If [font color="red"]37.c3 Re2 38.Kc1 Kg8 39.a4 g5[/font] then:
• If [font color="red"]40.fxg5[/font] then after [font color="red"]40...hxg5 41.Rd8+ Kg7 42.Rd7 Kh6 43.Rfxf7 Kxh5[/font] Black wins easily.
• If [font color="magenta"]40.hxg6[/font] then Black wins after [font color="magenta"]40...fxg6 41.Rh3 Re1 42.Rh1 Kg7.[/font]
• If [font color="darkred"]37.Rh3[/font] then Black wins after [font color="darkred"]37...g5 38.Rdh1 g4!! 39.Rxh4 Re1+.[/font]

37.Kc1 Bd4 38.c3 Be3+

• Also good is [font color="red"]38...Bc5 39.Kd2 Be3+ 40.Kc2 f5 41.Rxe3 Rxe3[/font] when 42...Re1 assures the queening of the pawn.

39.Kc2 f5 40.a4 a5 41.c5 Bxc5 0-1

• [font color="red"]42.Kd2 Be3+[/font] then:
• [font color="red"]43.Kc2 43...Kh7 44.Rd3 Bc5[/font] leaves Black up a piece.
• If [font color="darkred"]43.Rxe3[/font] then Black wins after [font color="darkred"]43...Rxd1+ 44.Kxd1 f1Q+.[/font]
• Mr. Nakamura resigns.
