P.S.
Here's what Wikipedia has to say about the London System-- https://en.wikipedia.org/wiki/London_System
The London System is a chess opening that begins with 1.d4 and 2.Bf4 or 2.Nf3 & 3.Bf4. It is a "system" opening that can be used against virtually any black defense and thus comprises a smaller body of opening theory than many other openings. The London System is one of the "Queen's Pawn Game", where White opens with 1.d4 but doesn't play the Queen's Gambit. It normally results in a closed game.
Sverre Johnsen and Vlatko Kovačević, in the introduction to their 2005 book Win with the London System, state:
Basically the London is a set of solid lines where after 1.d4 White quickly develops his dark-squared bishop to f4 and normally bolsters his centre with [pawns on] c3 and e3 rather than expanding. Although it has the potential for a quick kingside attack, the white forces are generally flexible enough to engage in a battle anywhere on the board. Historically it developed into a system mainly from three variations:
1.d4 d5 2.Nf3 Nf6 3.Bf4
1.d4 Nf6 2.Nf3 e6 3.Bf4
1.d4 Nf6 2.Nf3 g6 3.Bf4.
The corresponding Encyclopaedia of Chess Openings codes are D02, A46, and A48.
I recently received some free video files from Andrew Martin. He was pushing his Foxy Videos series. Since fhe files he sent me were free and free is my favorite word I took a look. The videos were about the London System. The London System gives white development and mobility and black winds up with a restricted game. I tried this system out in some of my own online games and sure enough Martin was right. This is a great system! Just as an example I put a game below that I got from Chessgames. com.
If anyone else is interested in this system and has thoughts, games and/or ideas he would like to share please do send them in. I would be very much intereested in your comments as well as tricks and traps and such for this system.
