Here's a selection of basic attacking ideas for attacking the King castled king's-side; the Queen's-side stuff at the end needs attention. These are the building blocks from which winning attacks are made; examples from actual play are given below. Unless you are playing a particularly unalert opponent, one idea alone will not be forceful enough to win: rather, each decisive idea is usually accompanied by a "supporting cast" of other features of the position.

Rook on eighth rank

Example: Nielsen - Bohm,Hans [C52] cr, 1979

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 d6 7.Qb3 Qd7 8.dxe5 dxe5 9.0-0 9...Bb6 10.Rd1 Qe7 11.a4 a6 12.Ba3 Qf6 13.a5 Ba7 14.Bd5 Nge7 15.Ra2 0-0 16.Bxc6 bxc6 17.Rad2 Rb8

  Perhaps its most common setting is in the late middle-game or ending:

Italian diagonal

This is surely the most basic attacking theme and is present throughout the examples below. I give two more direct exmaples:

Example: Schiffers - Harmonist [C55] Franfurt, 1887

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Bd2 Bxd2+ 8.Nbxd2 d5 9.exd5 Nxd5 10.Qb3 Nce7 11.0-0 0-0 12.Rfe1 c6 13.a4 Qc7 14.Rac1 Nf4 [14...Qf4] 15.Ng5 Neg6

Supporting cast: Knight on g5, Rook on eighth rank(!)

16.Re8 Rxe8 17.Bxf7+ Kh8 18.Bxe8 Ne2+ 19.Kh1 Nxc1 20.Nf7+ Kg8 21.Nh6+ Kf8 22.Qg8+ Ke7 23.Bxg6 hxg6 [23...gxh6 24.Qf7+ Kd6 25.Ne4#] 24.Qxg7+ Kd8 25.Qf8+ Kd7 26.Ne4 Qd8 27.Qd6+ Ke8 28.Nf6+ 1-0

 

Example: euwe - thomas [D69] (EUWE), 1934

1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 0-0 6.Nf3 Nbd7 7.Rc1 c6 8.Bd3 dxc4 9.Bxc4 Nd5 10.Bxe7 Qxe7 11.0-0 Nxc3 12.Rxc3 Black now plays the final part of Capablanca's freeing manoeuvre. 12...e5 13.dxe5 Nxe5 14.Nxe5 Qxe5 15.f4 Qe7 White has a temporary advantage in development, which is particularly clear in the positions of the Bishops. If White does not sieze the moment, the advantage will vanish, and Black's last move gives White the chance he needs.

  Now White can count up several advantages - good Bb3, good Rooks, exposed enemy King. Black may still organise a defence, given time. 20...Bb7 Now each Bishop looks good, but the other advantages have yet to be neutralised. [20...Be6 costs a pawn: 21.Bxe6 fxe6 22.Qg4+ Qg5 (22...Kh8 23.Rc7) 23.Qxe6+ Kh8 24.Rxf6 Rg8 (24...Rfe8 25.Qf7) 25.Rf2; 20...f5 21.Qh5] 21.Rcxf6 Qe4 22.Qd2 Kh8 [22...Rad8 23.Qg5+ Kh8 24.Rxf7] 23.Bxf7 Rac8 [23...Rad8 with good drawing chances 24.Qg5 (24.Qf2 Qe7 25.Bb3 Rxf6 26.Qxf6+ Qxf6 27.Rxf6 Bd5) 24...Rg8 25.Bxg8 Rxg8 26.Rf8 Qxg2+ =] 24.R6f2 Rcd8 [24...Qg4] 25.Qg5 25...Rd6 [25...Qd4 26.Bd5 Qg7 (26...Rxf2 27.Qxd8+ Kg7 28.Qg5+ Kf8 29.Qg8+ Ke7 30.Re1+ Kd6 31.Bxb7) 27.Rxf8+ Rxf8 28.Rxf8+ Qxf8 29.Qe5+ Qg7 30.Qe8+] 26.Bd5 1-0 26...Rxf2 27.Qg8# 1-0

Perhaps the commonest is the sacrifice Rf1xNf6 to eliminate the key defender of h7. But there is another that should be in every player's repertoire:

Castling Queen's-side

This is both more aggressive and more risky than castling King's-side. With O-O-O, the Rook is immediately placed for action in the centre, but the King is one square closer to danger. The defensive front a2-b2-c2-d2 is one square longer. The move Kc1-b1 may be necessary to secure the a-Pawn after a move or exchange of the Nc3.

  Much else is similar: for every Rf1xNf6 sacrifice White makes on the King's-side there is a ...Rc8xNc3 on the Queen's-side.

  Differences are due mostly to (a) prior movements of the c-pawn - where we might expect the f-Pawn to be still on f2, the c-Pawn often is out of line; and (b) Pawn storms where there is opposite-side castling - when Pawns may more freely be used to open lines away from your own King. [You can of course use Pawn storms when both sides have castled King's-side if the centre is closed or only semi-open, as in many Sicilian positions]. These differences have the consequence that play is much sharper and (because of the slowness of Pawns) careful timing is needed.

  Below I give an example of the consequence of moving the c-Pawn (Bodens's mate) and a typical situation with mutual mating attacks with opposite-side castling.

Example: Opposite-side castling [B75] 1993

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 Nc6 8.Qd2 a6 9.0-0-0 Bd7 10.g4 Rc8 11.Be2 0-0 12.h4 Opposite-side castling and asymmetric pawns/files usually adds up to a race to mate the opponent's King. Both sides may throw pawns forward to open up lines for the attack. Black in these situations has a head start in that the c-file is already open, but can always have another file with ...b7-b5-b4 12...Nxd4 13.Bxd4 Qa5 14.Kb1 e5 ! 15.Be3 Be6 16.a3 Rfd8 17.Bg5 Rd7 18.h5 Rdc7
