The London System
Memorization of complex opening lines is not worthwhile for players below master strength. It is boring and time consuming. Also it is far better for us mere alphabet players to understand the why's and wherefores. With this in mind, I have been investigating opening systems--note the word "systems" which means we are not following a memorized line. So far the best one I have come across is the London System which is often played by the top grandmasters. Here White places his Pawns at d4, e3 and c3; his Knights at f3 and d2; and his Bishop at f4.
The basic strategy for this opening is for White to present an inpregnable front so that any assault by Black weakens Black himself. Keep an eye on Black's King. If he castles make threatening moves to entice weakening "defensive" moves. If Black does nothing to weaken himself seek to lock the center and advance on pawns the Queen side seeking to crush your enemy slowly to death. One of the ideas in this system is occupation of e5 by White's Knight, Bishop or Pawn
