The Swedish GM Ulf Andersson is famous for his extreme dry playing style. In his games, his main objective is to stifle his opponents activities with the help of astute prophylactic maneuvers. Once this is fulfilled, he will slowly increase the value of his own assets by patiently accumulating small advantages. Very often, he will reach an ending with a small but enduring edge. Instead of being tired and unfocused, which happens to many other players, Andersson is fully energized here, because he thrives in this sort of position. His style of slow accumulation enables him to win games against strong opponents, where it is sometimes difficult to find any grave mistakes in their play. It appeared as though they were sucked into a slowly revolving vortex. I am convinced, that the following game of mine qualifies for having “Andersson grade”:

1) I went for a rigid structure which was favorable for me due to my opponent’s weak square d5.

2) After that, the game was one-sided. The only likely result was a draw or 1-0. This is exactly what Andersson likes. Even if the chance for the draw is very high compared to the chance of him winning, he might go for it as long as the chance of him losing is nil. Accordingly, the draw rate of his games is quite high. But, whenever his opponent defends with only second best moves, he will relentlessly pounce on that. Consequently, a slight initial advantage might be enough for Andersson, because his opponents tend to add to that later on.

3) I almost won the game without tactics. I only had to calculate some short variations in moments, in which I had to decide about the most efficient way to turn the bench vice another round. Defensive calculations have not been necessary at all.

4) I was very patient throughout the entire game and improved my position whenever I could before taking actions.

But please, have a look and decide for yourself.

universal significance of knowing the most important pawn structures. In
contrast to specific variations, which depend on your ability to memorize them
and hardly contain any exterior value, the knowledge of structures is the true
essence of your chess wisdom. It is neither bound to one place (a specific
line) nor does it depend on time (it cannot be refuted, like a specific order
of moves, hence it is timeless!). Consider the knowledge of structures your

corrections to your position as possible. They might be useful later on. Can
you imagine, with this harmless king move alone, I achieved four different
goals! Maybe you want to figure them out by yourself....Okay, here they are: 1. I
overprotected the Nf3 2. I moved away my king from a potential check on the
first rank (that could save me a tempo later). 3. I moved the king closer to
the center. Maybe, he will continue to f3, who knows. And 4., well that is
a bit of a Grandmaster secret, a method I used in many, many games. Maybe it
is the single most powerful weapon of all...... I passed the DUTY of moving
back to my opponent! After all, it is only when it is his turn to move, that
he can commit a mistake, right? According to my experience, there is hardly
anything as difficult as making a move when all you can do is wait. It is a
psychological problem. Being in a passive position is painful, and the natural
impulse is to get rid of this pain, by creating counterplay, for instance. But
what if there is no genuine counterplay? What if all the pseudo-active moves
only lead to more weaknesses and more problems in reality?} h6 {The motivation
of his move is clear, but now we have another pawn on black (the bishop cannot
use h6 for the moment) and even more light-squared weaknesses.....} 22. a4 $1 {
[%cal Ra4a5,Ra5a6] Diagram [#] Of course, it is important to use the board in
its entire width to attack your opponent. Black has to reckon now with
additional motives: 1. a4-a5xb6, thus creating a weakness on b6 which might
be attacked by Qb3 and Nc4 2. a4-a5-a6, thus creating a potential far
advanced passed pawn (Whites knight might attack the pawn a7 from b5, or, after an
exchange of queens, there might follow Nc4xb6!). 3. a4-a5 followed by Qa6.
This third plan looks like the most realistic one. By not changing an b6,
Black cannot actively defend his b-pawn with Qc6 (attacking e4), because he
still has to look after his pawn on a7. Depending on the circumstances, I
might transfer my king's knight to c4, augmenting the pressure on b6.} Nc6 {

the dangerous a-pawn.} 23. Nd5 {Finally! I worked for this to happen since I
