My advice to beginners is to not stick with one opening, but to play them all. Include wild openings like the Kings Gambit and Danish Gambit, as well as strategic openings like the Queen's Gambit. You will be out of 'the book' very quickly, and that's actually good. You'll be learning to play, rather than recall.<p>Another piece of advice: Study endgames before openings. Learn about K + P vs K, the elementary mates, (K + 2B vs K, and K + N + B vs K). Then keep going. I have had to 'finish off' opponents in tournament conditions with these combinations of pieces.<p>Lastly: Best chess book ever: <i>Winning Chess</i> by Fred Reinfeld and Irving Chernev. Of the dozens of chess books I've owned, this one is head and shoulders above the rest. All about middle game tactics, and mating patterns.
