Sicilian.
As white - Queen's Gambit Accepted, King's Indian Defence, Queen's Gambit Declined
Against 1.e4 - Sicilian, Caro-Kann, Scandinavian
Against 1.d4 - Queen's Indian, Blumenfeld Gambit, Queen's Gambit Declined
As white - The London system, Queen's Gambit Declined, The English opening
Against 1.e4 - The Caro-Kann, The Sicilian: Taimanov variation, The Sicilian: Hyperaccelerated Dragon
Against 1.d4 - The Kings Indian defense, The Dutch Leningrad variation, The Dutch Stonewall variation,
But in all honesty most of the time I only play the first from every category, especially in serious games.
OK a slight twist on the ever-present 'what's your favourite opening' topic... What are your three favourite openings in each of these categories? :
* As white
* As black against 1.e4
* As black against 1.d4
