Jussupow-Rubinstein System (3. e3) is a solid but not too ambitious variation for White. This setup most often includes Bd3, O-O, b2-b3, Bb2 and c2-c4. Black has a choice between the immediate d7-d5 and c7-c5 or a more or less symmetrical piece arrangement: b7-b6, Bb7, d7-d5 and Bd6.
The Colle System is a very simple plan for White and, as such, quite suitable for the beginners. White plays e2-e3, Bd3, O-O, c2-c3 and Nbd2, often followed by Ne5 and f2-f4.
London System (3. Bf4) has some similarities with the 3. e3 system. White usually proceeds with e2-e3, h2-h3, Bd3 and O-O. Black, again, has a few paths to obtain equal chances, but White’s cautious play typically does not allow his opponent too much activity.
[Diagram: White to Move] Black seems able to defend from White’s threats, and black Queen is planing to flee over b4 to a5. How should White continue to obtain the advantage?
