Black can hope to make a point about the early development of the Bishop by attacking b2. Sometimes White plays it as a gambit, sometimes White defends with Qc1/Qc2, sometimes White blocks with Qb3, when the Queens are likely to be swapped. One thing that I got out of looking at London games by Bronstein and others is the paradoxical power of doubled pawns. Sometimes Qb3 Qb6 Qxb6 axb6 (or the same with a swap on b3) showed the doubled pawns as a weakness, but sometimes the open a-file and chances to break twice with the b-pawn proved stronger. The creative Bronstein can be found on both sides of the argument.

In practice, passive or too-simple play by Black can lead to trouble, and, with a space or development advantage, White can attack happily on either side of the board. I've lost and struggled against the London throughout my chess career, and watched Peter Lane (formerly of this parish) have some real walk-throughs against strong players with this system. Repertoire books (Soltis 1988, Johanssen & Kovacevic 2009) do give unrealistic numbers of White wins (2/40 losses in Soltis) but they also give you some recipes about how to play, and a player with a plan will usually beat a player without one. It all depends on what ideas you can bring to the game. Magnus Carlsen brings more to a game than most, and he can beat top Grandmasters with the London. [p] John Cox had a superb introduction to 'Dealing with d4 Deviations': [BLOCKQUOTE] I begged Everyman Chess to let me write this book. All my chess-playing life I have had a terrible record against these feeble variants, as I saw them. The final straw was being utterly slaughtered by Richard Pert in a London league match in the 4 e3 line in Chapter 9. I wanted the incentive to study them and give myself the opportunity to put this right. And for me, it's worked splendidly. I believe I have really learned something about these systems, and if I am able to pass on to the reader the confidence I have now gained myself, then the job will have been well done. ... [p] I think it's worth examining why I used to do so badly against these systems. Dealing with these openings successfully is a matter of psychological approach among other things – it's not by chance that every work from Black's point of view called them 'annoying' or some synonym. I set out what I now feel were my main failings in this area in the hope others might recognize some of theirs and be inspired to remedy them at less cost in points than I managed. [p] 1) The most obvious point – I didn't actually have a repertoire at all against, say, the Colle. You just play chess, right? Develop the pieces and equalize. I remember Grandmaster Vlatko Kovacevic playing the Colle against me back before databases. I had no idea this was his customary weapon of mass destruction, and I thought I must have sat down at the wrong board. A GM playing 3 e3?? [p] With that attitude, it won't surprise you to learn I got torched on the kingside around about move 25. Only the fact that the game was played in a comparatively minor event has saved me from appearing in every Colle book since on the wrong end of a classic White crush. Time has mercifully obscured the details, but I know I went ...d5 and ...c5. Pretty soon a knight appeared on e5 and I didn't seem to be able to shift it. Shortly after that, either the h- or the g-pawn arrived on the premises. Then came Re3, Qh5, and the next thing I knew I was looking like something out of 1001 Winning Chess Combinations. That wasn't the only such debacle, either; every time my opponent played one of these vile things I was behind on the clock as I worked on my conception of the wheel, and just as you'd expect some of my wheels came out square. Hopefully the remedy to this is obvious – you hold it in your hands. [p] 2) I was bored by these openings: I didn't consider them interesting. [p] 3) Not only did I not consider them interesting, I didn't consider them dangerous. [p] 4) A less obvious point, this: to combat these openings successfully requires a good knowledge of many structures. A good chess education, in fact. [p] 5) I didn't experience the adrenalin surge I got defending 'my' openings. [p] 6) Lastly, I wasn't playing set-ups I was happy and had experience with. [p] John Cox [/BLOCKQUOTE] [p] And a little tribute to England's most notable exponent of the system: [BLOCKQUOTE] It personally brings back some memories of Michael Franklin at some quickplays in London I used to play at. A very strong player, and a very frustrating player to play against. Imagine fantastic quality Staunton sets, and that horrid London system bishop cutting across the diagonal, just waiting with its little cutesy pigeon hole on h2 made by the h3 move, to puncture the opponents pawn structure etc - and kill all the enthusiasm of the up and coming young players. [p] If you imagine Michael Franklin as a kind of chess Dracula, sucking all the enthusiasm and counterplay out of the position and his opponents, you begin to feel the nature of the opening and the people that really excel at using it. And yes even with a minority attack, those sorts of players will just wait to pounce on any weaknesses you dare create on the Queenside. They literally look forward to you entertaining them trying to attack them anywhere waiting to pounce on weaknesses created ... [p] Tryfon Gavriel [/BLOCKQUOTE] Let's look at some specific lines.
