CHESS FUNDAMENTALS,“Bring out N's before bringing out B's.”

3 … Bb4 4 b3

THE IDEAS BEHIND THE CHESS OPENINGS, "Most promising for White, if Black persists in avoiding the Four Knights', is 4 Bb5, so that on 4 ... Nge7 (of course 4 ... Nf6 is possible); d4! exd4 6 Nxd4 gives him the better center position."

4... Nf6 5 Bb2

TEACH YOURSELF BETTER CHESS, "B's are best deployed on the longest diagonals - the ones from corner to corner."

5 … O-O 6 d3 d6 7 Qd2? Bg4 8 O-O-O

MASTERING THE CHESS OPENINGS, "One of the most important guidelines in chess is to protect your K from harm."

8 … BxNf3 9 g2xBf3 BxNc3 10 QxBc3 Nd4 11 f4! Re8 12 fxe5 dxe5 13 Rg1

MODERN ART OF ATTACK, "The attack against an opposite castled opponent can focus on the creation and efficient use of an open file."

13 … Rc8 14 Qd2??

RYBKA recommends 14 f4, to keep up the pressure.

14 ... c5

15 Qh6

THE GAME OF CHESS, "One of the most frequent and most dangerous forms of attack is the pin."

15 … g6

THE COMPLETE CHESS PLAYER, "So long as the pawn in front of K remains unmoved, it is relatively difficult to work up a convincing attack; but let one of these lowly pawns advance a step, and very often the whole castled position totters on the brink of disaster."

16 Bh3 Rc6 17 Kb1 Nf3 18 Rg3 Nxh2

RYBKA recommends 19 Rh1 +-; bringing another piece into action and trapping the N.
