GiuocoPiano-4c3 and Moeller Attack 01

Giuoco Piano – Attacking with 4.c3Richard Westbrook, 2006.

1

White can play for an attack at move four with c2-c3 (instead of d2-d3, 0-0, or other move.) It is a time-honored, aggressive line which gives the first player good chances. This lesson explores some of the main lines from White’s perspective and provides sample games. We reach the first important position after the moves:

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 …XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-sn-+05+-vl-+-+-04-+LzPP+-+03+-+-+N+-02PzP-+-zPPzP01tRNvLQmK-+R0xabcdefghy

6… Bb4+

Other moves are less accurate: e.g.,6... Bb6?7.d5 Ne7

If 7...Nb8 8.e5 Ne4; andIf 7...Na5 8.Bd3 c5 White has fine play.

8.e5 Ne4 9.0–0 0–0 10.Qe2 Nc5 11.b4 Na6 12.d6 cxd6 13.exd6 Ng6 14.Bg5 Qe8 15.Be7 Kh8 16.Nc3 Nxb4 17.Rae1 Nc6 18.Bxf8 Qxe2

19.Rxe2 Nxf8 20.Re8 Kg8 21.Nd5 g6 22.Ne7+ 1–0. Euwe-Jutte, 1927.

7.Nc3 …

White sometimes plays 7.Bd2 or 7.Nbd2, but the text is the most accurate.XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-sn-+05+-+-+-+-04-vlLzPP+-+03+-sN-+N+-02PzP-+-zPPzP01tR-vLQmK-+R0xabcdefghy

7... Nxe4

7... 0–0? 8.e5 Ne4 9.0–0! Nxc3 10.bxc3 Bxc3 11.Ng5! Bxa1?

Black must find 11... d5 12.Qd3 g6 13.Qxc3 dxc4 14.Be3 Qd5 White will win the c4-pawn, but the exchanges equalize the position.

12.Qh5! h6

This is "Greco's Mate" pattern, but there is no mate unless Black blunders. Nevertheless, White wins decisive material.

13.Nxf7!! d5 14.exd6! Rxf7 15.Bxf7+ Kf8

15... Kh8?16.Bxh6!! Bf5!?17.Bg5+ Bh7 18.Bxd8 Rxd8 19.Bg6 Kg8 20.Qxh7+ Kf8 21.Qh8#.

15... Kh7?16.Bxh6! Qxd6 17.Bf4+ Qh6 18.Bxh6 gxh6 19.Qg6+ Kh8 20.Qxh6#.

16.Bc4! Qf6!? 17.Re1 Bf5 18.d7 g5 19.Re8+ Kg7 20.Rxa8 Bg6 21.Rg8+ Kh7 22.Rxg6! Qxg6 23.Qe2 Black is “toast.”

One hundred years ago, after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4Bb4+ 7.Nc3 d5 instead of 7…Nxe4, was a popular continuation for Black.

(See diagram, top of next column.)

7... d5.XIIIIIIIIY8r+lwqk+-tr07zppzp-+pzpp06-+n+-sn-+05+-+p+-+-04-vlLzPP+-+03+-sN-+N+-02PzP-+-zPPzP01tR-vLQmK-+R0xabcdefghy

But we now know this to be bad, because after

8.exd5! Nxd5 9.0–0!! …White is threatening to win a piece, and after (I) 9... Nxc3 10.bxc3 …

Perhaps even stronger is 10.Qe1+ Ne4 11.Qxe4+ Qe7 12.Qd3.

10... Bxc3? 11.Qb3! …

White's threats against f7 and c3 are decisive. For example,XIIIIIIIIY8r+lwqk+-tr07zppzp-+pzpp06-+n+-+-+05+-+-+-+-04-+LzP-+-+03+Qvl-+N+-02P+-+-zPPzP01tR-vL-+RmK-0xabcdefghy

11... Bxa1 12.Bxf7+ Kf8 13.Ba3+ Ne7

White has several winning paths; they should all be studied carefully!

The best is the amazing14.Bg8!! Qe8

14... Rxg8??15.Ne5 Be6 16.Qxe6 Qe8 17.Qf5+ Qf7 18.Qxf7#.

15.Re1 …XIIIIIIIIY8r+l+qmkLtr07zppzp-sn-zpp06-+-+-+-+05+-+-+-+-04-+-zP-+-+03vLQ+-+N+-02P+-+-zPPzP01vl-+-tR-mK-0xabcdefghy

Threatening Rxe7 followed by a quick mate.For example, (skip Black’s 15th move.)16.Rxe7 c5 17.Rf7+

Or, 17.Bxc5 Be6 18.Rxe6+ Qe7 19.Rxe7 Rxg8 20.Qf7#.

17... Kxg8 18.Rd7+ Qe6 19.Qxe6+ Kf8 20.Bxc5#.

So, after 15.Re1, Black might play15... Bxd4 16.Nxd4 Rxg8 17.Qf3+ Qf7 18.Bxe7+ Ke8 19.Bg5+ Be6 20.Qd5!! g6

21.Nxe6 Rg7 22.Bh6 Rb8 23.Nxg7+ Kf8 24.Ne8+ Kg8 25.Nf6+ Kh8 26.Qxf7 Rd8 27.Bg7#

Other winning paths (although not quite as strong) are -XIIIIIIIIY8r+lwq-mk-tr07zppzp-snLzpp06-+-+-+-+05+-+-+-+-04-+-zP-+-+03vLQ+-+N+-02P+-+-zPPzP01vl-+-+RmK-0xabcdefghy

14.Rxa1 Bf5 15.Re1 g6 16.Ng5 threatening Qd3 with a crushing attack.

And,14.Ng5 Qxd4 15.Re1 (15.Rd1 is good, too.) 15... g6 16.Be8! Qf4 17.Rxe7 is overwhelming.

Returning to Black’s 7th move error, 7…d5?XIIIIIIIIY8r+lwqk+-tr07zppzp-+pzpp06-+n+-sn-+05+-+p+-+-04-vlLzPP+-+03+-sN-+N+-02PzP-+-zPPzP01tR-vLQmK-+R0xabcdefghy

after 8.exd5 Nxd5 9.0-0, even worse is for Black is

(II) 9... Bxc3?10.bxc3 Nxc3 11.Qe1+ which loses a piece.

If 10... 0–0 (instead of …Nxc3)11.Qc2 threatens Ng5 and allows White to build a strong attack. For example,XIIIIIIIIY8r+lwq-trk+07zppzp-+pzpp06-+n+-+-+05+-+n+-+-04-+LzP-+-+03+-zP-+N+-02P+Q+-zPPzP01tR-vL-+RmK-0xabcdefghy

11... h6

Not, 11... Nf6? 12.Ba3 Re8 13.Ng5 Be6 14.Nxe6 fxe6 15.Rae1 Nd5 and the knight has to return, but White still has a strong attack after - 16.f4 threatening Rf3-h3, with Bd3 to add pressure to the light squares. +-.

12.Re1 Bg4

Not, 12... Be6?! 13.Bxh6!! gxh6 14.Rxe6 fxe6 15.Qg6+ Kh8 16.Qxh6+ Kg8 17.Qxe6+ Kg7 18.Bxd5 +-.

Weaker is 17...Kh8 18.Qh6+ Kg8 19.Qg6+! Kh8

20.Ng5 forcing Black to give up the queen in order to stop mate.

13.Ne5 Nxe5 14.Rxe5 c6 +/-.

If 14... Nf6? 15.f3 Be6 16.Bxe6 fxe6 17.Rxe6 +-.

If Black errs at move 7, then after 8.exd5! Nxd5 9.0–0!! …XIIIIIIIIY8r+lwqk+-tr07zppzp-+pzpp06-+n+-+-+05+-+n+-+-04-vlLzP-+-+03+-sN-+N+-02PzP-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

Relatively best is (9C) 9... Be6 10.Bg5 Be7 11.Bxd5 Bxd5 12.Nxd5 Qxd5 13.Bxe7 Nxe7 14.Re1 but White has a strong position. Wilhelm Steinitz beat Bardeleben (Hastings, 1895) in a classic game from here.

Returning to the main line, after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Nc3 Nxe4, White continues -

8.0–0! …

Greco analyzed this line around 1620, but his ideas were disregarded for over two hundred years! (See diagram, top of next page.)

8... Bxc3!

This is the most dangerous move for White to face.

Harmless is 8... Nxc3 9.bxc3 Bxc3 XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-+-+05+-+-+-+-04-+LzP-+-+03+-vl-+N+-02P+-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

White has two good continuations 10A) 10.Ba3! d5 11.Bb5 Bxa1 12.Re1+ Be6 13.Qa4 Rc8!? 14.Bxc6+ bxc6 15.Ne5 Qf6 16.Rxa1 Bd7 17.Re1 Kd8 18.Qxa7 Re8 19.Bc1 …Threatens Bg5!! White's pressure is compensation for the material sacrificed.

10B) 10.Qb3!? Bxa111.Bxf7+ Kf8

Not 11... Ke7?? 12.Re1+! …Leads to mate and is stronger than Bg5! 12... Kf8 13.Bh5 d5 14.Qxd5!! Be6 15.Qxe6 Qe7 16.Qf5+ Qf6 17.Ba3+ Nb4 18.Bxb4+ c5 19.Bxc5+ Kg8 20.Qd5+ Qf7 21.Qxf7#.

12.Bg5 Nxd4 13.Qa3+ Kxf7 14.Bxd8 Rxd8 15.Rxa1 Ne6 16.Re1 …White’s lead in development is compensation for the material deficit, but a win is far from certain.

Even the sacrifice on f7 can be played, but it can be refuted with best defense.XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-+-+05+-+-+-+-04-+LzP-+-+03+-vl-+N+-02P+-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

10C) 10.Bxf7+?! Kxf7 11.Bg5 Qg8 (amazingly, best!)12.Qb3+ d513.Qxc3 …With approximately equal chances if White acts quickly. The long-term prospects probably favor Black.

Finally, if after 8.0-0!, XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-+-+05+-+-+-+-04-vlLzPn+-+03+-sN-+N+-02PzP-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

If Black also castles, 8...0–0 9.d5! (9.Nxe4? d5!) Bxc3 10.bxc3 Ne7 11.d6 …and White went on to win in Spielmann-Cohn, Carlsbad, 1911. But safer is 11.Re1!

Back to the main line. After the moves, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Nc3 Nxe4 8.0–0! Bxc3,

White plays 9.d5! XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-+-+05+-+P+-+-04-+L+n+-+03+-vl-+N+-02PzP-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

This is the "Moeller Attack," named for Jorgen Moeller whose 1898 analysis put new life into this variation. The best way for Black to defend is 9...Bf6. Black can also try:(9a) 9…Na5?!;(9b) 9…Nd6?!;(9c) 9…Ne7!?;(9d) 9…Ba5!?; or(9e) 9…Ne5!?.

(9a) Dubious is 9...Na5 10.Bd3! Nc5 11.bxc3 Nxd3

11... 0–0? 12.Bxh7+!! Kxh7 13.Ng5+ Kg6

If 13... Kg8 14.Qh5 Re8?Black must play ...Qxg5 to survive.15.Qxf7+ Kh8 16.Qh5+ Kg8 17.Qh7+ Kf8 18.Qh8+ Ke7 19.Qxg7+ Kd6 20.Qg6+ Re6

If 20... Kxd5? 21.Rd1+ Kc4 22.Rd4+ Kxc3 23.Bb2+ Kxb2 24.Qb1+ Kc3 25.Qb4+ Kc2 26.Rd2#.

21.dxe6 dxe6 22.Nf7+ +-

14.h4!! …Threatens h5 as well as Qg4, both of which are devastating. For example, (skip Black’s move)

XIIIIIIIIY8r+lwq-tr-+07zppzpp+pzp-06-+-+-+k+05sn-snP+-sN-04-+-+-+-zP03+-zP-+-+-02P+-+-zPP+01tR-vLQ+RmK-0xabcdefghy

15.Qg4 Kf6 16.Re1 Ne6


7

17.Nxe6 fxe6 18.Bg5+ wins the queen and more.

And 15.h5+ Kh6 16.Qg4 …threatens mate in 3; or Nxf7+ picks up the queen.

Returning to the variation 9...Na5!? 10.Bd3! Nc5 11.bxc3 Nxd3 -

12.Qxd3 0–0 13.Ng5 …

Worth considering is the thematic 13.d6 cxd6?! 14.Ng5 g6 15.Ne4 +/-.

13... g6 (13...f5 14.d6!) 14.Qh3 (or d6) h5 15.Ne4 …White has an excellent game.

After White plays 9.d5! XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-+-+05+-+P+-+-04-+L+n+-+03+-vl-+N+-02PzP-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

(9b) Weak is 9...Nd6?Because it is too cramping. 10.dxc6 Nxc4 11.Qe2+ Be5

Not 11... Qe7?! 12.Qxc4 Ba5 13.Bg5 …White has regained his piece! +-.13... f6 14.Qd5 dxc6 (14...fxg5? 15.cxb7)15.Qxa5 0–0

16.Rfe1 +-.

12.Nxe5 Nxe5 13.Qxe5+ Kf8

(13...Qe7?? 14.Qxg7 Rf8 15.Bg5!)

14.cxd7 Bxd7 15.Be3 +/-;


(9c) Somewhat better is 9...Ne7!? 10.bxc3 …

But the Ne4 is a problem since it lacks a good retreat. For example, 10...0–0 …

10... Nxc3? 11.Qd4!; or,

10... Nd6!? 11.Bb3 0–0 Black has trouble completing his development.

11.Re1 Nf6 12.d6! cxd6!? 13.Bg5 Nf5 14.Qc2! …White has a good game.


8


(9d) The rare 9...Ba5!? 10.dxc6 dxc6 11.Qa4 Bb6 12.Bxf7+ Kxf7 13.Qxe4 certainly favors White.

Finally, After White plays 9.d5! XIIIIIIIIY8r+lwqk+-tr07zppzpp+pzpp06-+n+-+-+05+-+P+-+-04-+L+n+-+03+-vl-+N+-02PzP-+-zPPzP01tR-vLQ+RmK-0xabcdefghy

(9e) A complicated line is 9... Ne5 10.bxc3 Nxc4 11.Qd4 0–0

If 11... Ncd6? 12.Qxg7 Qf6 13.Qxf6 Nxf6 14.Re1+ Kf8 15.Bh6+ Kg8 16.Re5 Nfe4 17.Re1 f6 18.Re7 Nf5 19.R1xe4 Nxh6 20.Re8+ Kg7 21.R4e7+ Nf7

22.Rxh8 Kxh8 23.Rxf7 Kg8 24.Re7 (or Rxf6) +-.

12.Qxe4 Nb6

12... b5 13.a4 c6 14.axb5 cxb5 15.d6 +/=. Black has difficulty in untangling the position. In Dzindzhichashvili-Karpov, 1988, after 15.Qd4 Black misdefended with 15...Nb6 when ...Bb7 would have given him the better game.

13.d6 (A blocking sacrifice!) cxd6 14.Ng5 f5

If 14... g6 15.Qh4 h5 16.Ba3 Qf6 17.Rfe1 Nd5 18.Rad1 Nxc3 19.Rxd6 Ne2+

Not 19... Qd8?? 20.Bb2! Qa5?? 21.Nxf7 Rxf7 22.Rxg6+ Kh7

22... Rg7? 23.Qf6 Ne2+ 24.Rxe2 Qe1+ 25.Rxe1 Rxg6 26.Qxg6+ Kf8 27.Re8#.

23.Rg5! +-.

20.Kf1 Qf4 21.Qxf4 Nxf4 22.Rd4 Ne6 23.Nxe6 dxe6 24.Bxf8 Kxf8 25.Rc1 +/= .

10.Re1 Ne7!

Castling now is risky for Black:10... 0–0?!11.Rxe4 Na5!? 12.Bd3 d6 13.g4! … This thrust is thematic in these kinds of positions! 13... h6 14.h4! …XIIIIIIIIY8r+lwq-trk+07zppzp-+pzp-06-+-zp-vl-zp05sn-+P+-+-04-+-+R+PzP03+-+L+N+-02PzP-+-zP-+01tR-vLQ+-mK-0xabcdefghy

11.Rxe4 d6

Again, Black must be careful about castling! 11... 0–0!? 12.d6! cxd6 is unclear. But not, 12... Ng6? 13.Qe2! followed by Bxf7+ etc.

10

We have reached an important position! Black has only two significant moves:13...0–0 and 13...h6. The modern move is

13... h6!14.Qe2! …

White can try an interesting sacrifice, but Black has an adequate defense: 14.Nxf7?! Kxf7 15.Qf3+ Nf5!

Not 15... Kg8? 16.Rae1 Qf8 (16...Ng6? 17.Re8+!) 17.Qc3 Bf5 18.Rxe7 +-.

16.g4 Qf6 (16...Rf8 17.gxf5 Kg8) 17.gxf5 =/+.

14... hxg5 15.Re1 Be6

Black must close the e-file! If 15... 0–0? 16.Rxe7! +/-.

22.Qb3 …White's pressure is compensation for the pawn.

In the main line, the traditional move is 13... 0–0, but this allows -XIIIIIIIIY8r+lwq-trk+07zppzp-snpzpp06-+-zp-+-+05+-+P+-sN-04-+L+R+-+03+-+-+-+-02PzP-+-zPPzP01tR-+Q+-mK-0xabcdefghy

14.Nxh7! …

Other moves for White are insufficient!

14... Kxh7 15.Qh5+ Kg8 16.Rh4 f5

Black can also play ...f6, but should fight for space at every opportunity!

17.Qh7+ Kf7 18.Rh6 (stops ...Ng6) Rg8The only reasonable move. 19.Re1 Kf8

If 19... Qf8 20.Bb5 threatens Ree6, which wins instantly. 20...Rh8 21.Qxh8 gxh6 22.Qh7+ Kf6 23.Rxe7 Qxe7 24.Qxh6+ leads to perpetual check.
