**Creating problems**

Winning a game of chess is all about creating problems for our opponent. A wolf is a stronger chess player than a rabbit, and so is the fox. The problems you create can be completely diverse in nature. Fierce attacks and brave sacrifices put your opponent under extreme pressure and even if a sacrifice turns out to be incorrect in the light of analysis, it might be too much to take for your opponent in the heat of the battle. The many incorrect but highly successful sacrifices of Mikhail Tal provide ample evidence for this. However, problems and pressure can also come along in the shape of subtle positional play, capitalizing on structural flaws, such as weak pawns or weak squares. But that’s not all. The perfect fox also incorporates psychological warfare in his overall strategy. Let’s say you have a superior position, in which your opponent cannot do very much. On the other hand, his position is too solid to be taken by storm. Normally, the best thing to do is to engage in maneuvering. Top priority is not to lose control and to preserve the favorable status quo. Next on the agenda is looking for ways to improve your pieces or to create further weaknesses in his structure. If all your pieces are located in good positions and there is no easy (risk free) way to create more weaknesses in his camp, the next thing to do is – to do nothing. What I mean is the smart way of doing nothing, of course. Playing Kh1-g1-h1-g1…. might infuse him the idea of just copying you with Kh8-g8-h8-g8….Your doing nothing must look like some kind of constructive plan. It can also incorporate simple to meet threats, like little pin pricks. The whole process will be tiring for your opponent. He will also have a lot of time to think about his past mistakes, which brought him into such a passive situation. This mixture of boredom, tiredness and self-conflict could finally prove too much tension or dis-ease for him to endure. He might want to leave all of this behind and then it happens, this weakening pawn move which will finally trigger his demise.

Freedom

Freedom is universally regarded as something positive, as it is a basic requirement of human nature. However, there is also a downside to it, as having more freedom also means having more options to harm yourself. The concept of negative flexibility is based on this simple truth. Self-harming is normally related to either a wrong or unclear perception of reality (for instance a situation or a system like chess) or a wrong perception of oneself. This second point has a lot to do with being unaware of self-sabotaging programs which constantly run in the background. According to experts, the brain is operating 95% of the time in this often destructive auto-pilot mode and only 5% in the state of full consciousness. It is possible that all vices originate in some way from ignorance or bad perception. Professionals in all areas of life are trying to take advantage of these human shortcomings. In the capital markets laymen are punished for being too greedy, too fearful, too impatient or for being overconfident. Smart business men exploit the vanity of other protagonists in order to get hold of valuable information. Chess is another area, where sinning (disrespecting reality) means asking for trouble. The above example was featuring lack of patience. Let’s move on to laziness.

**Laziness**

Playing 1.e4 is high maintenance and hence comes with obligations. If you are not willing to honor them by putting in the necessary amount of hours, all you get is equal positions with White and most likely inferior positions with Black (given that you display the same behavior pattern with both colors). That way, chess becomes an uphill fight. If you wonder why you are getting outperformed by less talented peers… Well, the perma-handicap you are playing with could be the answer.

By capitalizing on negative flexibility, the Four Knights concedes a lot of room for white players to sin in the context of laziness. The most popular line for the lazyman is **1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Nxc6 bxc6 7.Bd3? **(correct is 7.e5)

The motivation is clear. By releasing the tension in the center with 6.Nxc6 White is permitted to finish his development undisturbed with 7.Bd3, 8.0-0 and then, for example 9.Qe2, 10.b3, 11.Bb2. Evidently, you don’t need to know any theory when deciding to play such a chain of nondescript routine moves. In post 57 I presented the statistics of the tabiya of 6.Nxc6, which arises after 6..bxc6 7.e5 (not 7.Bd3?) Nd5 8.Ne4 Qc7 9.f4 Qb6 10.c4 Bb4 11.Ke2 f5. The game count is 570.

Now, let’s have a look at the statistics of 7.Bd3?

More than 115o games have continued with inferior moves, of which 7.Bd3 is the biggest part with 923 games. The conclusion is that you meet doubtful moves twice as much as the critical main lines. Obviously, this puts the apparent menace coming from 6.Nxc6 in a somewhat different perspective.

After 7.Bd3 d5 your engines indicates instant equality. No wonder, if you consider Black’s superiority in the center. As a matter of fact, this majority gives Black already a slight positional initiative. It is White who has a smaller margin of error and who has to try a bit harder to maintain the balance. A minimalist approach would have been to cover this topic very briefly, as equality means “mission accomplished” within the context of a black repertoire. I could have indicated some basic plans and then moved on to my work on other, more critical lines. Instead, I covered this variation in great detail:

As you can see, it stretches over 12 single analyses. This explicit treatment is in line with my overall philosophy of providing my clients with the biggest possible degree of orientation. Of course, nobody is forced to study the entire material. Everyone can decide for himself, what he regards as necessary, critical or interesting. In any case, it is good to have the material in its entirety for reference purposes. If you play a blitz game on a server, you can look up afterwards whether your way of playing was in line with my theory. If you are a friend of active learning (see post 50) you will insert your blitz game in the material and analyze it with an engine, thus enriching my original work.

There is yet another, more specific reason for the extensive coverage of 7.Bd3, which has to do with being street wise. We have to be aware of what has relevance not only in academia but also in real life. As the above statistics indicate, 7.Bd3 is more popular than anything else. This is particularly true for the subjective reality of my clients, which plays out mostly on the level between 1900 and 2300. Here, dubious moves such as 7.Bd3 are even more frequent than suggested by the general statistics above, which are mainly based on master games.

Equalizing with Black is the predominant aim in opening theory. However, what about being flexible and shifting your aim according to the actual position? As I mentioned before, with his mobile pawn center Black can already start thinking in terms of playing for an advantage, in case White is acting carelessly. Hence, my intention was to highlight the big amount of =+-potential which is hiding in the position.

My decision for the example line presented below derived from the notion that it might be of highest interest to see what happens, if White plays in the most aggressive manner. As it is line 3 (65) of the above list, the analysis just jumps right into the topic. Introductory words are only given in the first line (63).

Together with post 57 I have provided you now with a good idea of what to expect from my material. If you happen to be interested in the 143 analyses, please have a look at my Four Knights sub-page, which has been updated recently.
