Compared to to classical} (1... e5 {the Sicilian has the  advantage of leading to position with an unbalanced pawn structure, which - at  least if you ask me - makes the game more interesting.}) 2. Nf3 d6 {Playing  the Black side of a chess game at a high level one could say that there are  two main strategies: 1. Forcing play, constantly simplifying and keeping the  balance. 2. Trading in information; making moves that keep a maximum of  uncertainty as to how you will proceed. (The famous GM Adorjan even goes as  far as saying that Black has an "advantage" in information, since White makes  the first move and therefore is the first to show his/her hand. These ideas  are exemplarily explained in Jonathan Rowson's book "Chess for Zebras")} 3.  Bb5+ ({Until a few years ago} 3. d4 {was played almost universally. After} cxd4  4.

I wonder to what extent he will keep this attitude in their upcoming match?}) 3... Nd7 ({Last year, in  the Masters final, these two chess giants had an encounter with the same  colours.

Qxd4 a6 {Black wants to "clarify" the position; the point is that Black does  not have a good alternative to taking the knight on d7, whereas if Black had  waited with a7-a6, then the situation might have changed and the bishop could  have stayed on the board.} 6. Bxd7+ Bxd7 7. c4 {White is at a junction here  and can choose between two quite different types of setups. The one in the  game says: "you have the bishop pair (which is supposed to be good) but I have  a lot of space and will try to smother you slowly".

Ne1 $1 {A general trend in both chess  and go is that the new generations are less concerned with what is "proper" or  - as we say in the chess world - "principled". The development in computer  chess has proven that there are more possibilities than we might otherwise  have thought. Here - however - we have an example of a common occurrence in  chess; a position where principles collide! On one hand you are not supposed  to move backwards with pieces, nor "forget about development" (bishop on c1  stays where it is). On the other hand the knight that just moved is on a  mission, heading for the weak square d5. (Weak in the sense that it cannot be  protected by a Black pawn).} O-O {With this move Black finishes the basic  developing phase. Now comes the old tricky question: where to put the rooks?}  15.

Ergo, when White puts one of the knights there...} 22. Ned5 {then Black plays}  Bd8 $1 {avoiding trades. Now White has to find an efficient use for Nc3.} (  22... Bxd5 23. Nxd5 Bd8 24.

Nxc8 {with a complete disaster.}) ({Still this  move surprises me a bit. The normal thing to do here would be to move the King  towards the center and not away from it:} 24... Kf8 {The only reason - that I  can see - why the World Champion would play differently is that - in some  lines - the h-pawn could be harassed with Be3 if Black continues with g6. A  bit too subtle too bee true maybe, but I really cannot see another reason. I  weaker player might think that the King could get into trouble because of the  two knights, but I very much doubt such a thought would enter the mind of the  World Champion.}) 25. Kf1 {In the endgame (a somewhat diffuse concept, but  here it depends on the fact that there are no queens on the board) the Kings  should walk towards the center.

The equivalent operation in chess is much simpler;  calculating the material. A short calculation of that sort gives us at hand  that White is leading with one pawn (1 point), but the problems for Black does  not stop there. Further reasons for worry is the weak pawn on a5, the passive  knight on f8 and the doubled e-pawn. Black's compensation consists of an  active rook on the second rank and a semi-active bishop. These compensatory  aspects of the position are good enough at the moment, but can easily cease to  be; they are both of a dynamic nature, whereas the White advantage is of a  static nature. If White can disarm the Black activity, then White should win  rather easily.}) 27... Bxd5 $1 28. Rxd5 Rxc3 29. Nxc3 Rc6 30. Be1 Nc5 31.
