So now there is another school of thought, saying White players can get better practical chances by avoiding the main lines after 2. c2-c4, and instead play with a more solid centre for activity on the wings, or perhaps playing a simple developmental move and only playing in the centre when Black's activity has been limited.
One other common theme is to play the Bc1 out early, to exchange off the Black Knight on f6 (the best defender of the castled King) and perhaps create weaknesses. We can see all these themes at work in the following game, where the wily Korchnoi leads the young Karpov up an unfamiliar alley and duffs him up:
