Chess is full of surprises that even a world champion like Magnus Carlsen, with encyclopedic knowledge of opening theory, can still be caught napping. A very fine performance by the tournament runner-up.

W: T. Radjabov (AZE)

B: M. Carlsen (NOR) Pirc Defense

1. d4     g6; 2. e4     d6; 3. Nf3     Nf6; 4. Nc3    Bg7

The Pirc Defense (named after five-time Yugoslav champion Vasja Pirc (1907-1980), has not been popular among leading GMs in recent years owing to its modest outlook, which allows white to establish a center with pawns on e4 and d4. As former world champion Garry Kasparov once said, “The Pirc Defense is hardly worth using in tournaments of highest category, as it gives white too many opportunities for anybody’s liking.”

5. Be2    O-O; 6. O-O    a6

Normally 6....Nc6 is played. Nevertheless, black’s last, intending an early ....b5, is acceptable.

7. a4      Nc6; 8. Be3     b6

8....e5 is a fair alternative, according to the engine.

9. d5      Nb8

The retreat of black’s knight seemed passive. . A better try is 9....Nb4.

It is vital to play 20....Qc8, as suggested by the engine. After the text, white gains substantial positional superiority..

21. axb5    axb5; 22. Bf2     h5; 23. Ra5!    ....

An excellent move which gains a pawn, while his queenside attack goes on unabated.

23....      Rxa5; 24. bxa5    Ra8; 25. Nxb5    d5; 26. Nd4    Nf6?

27. a6!     ....

The march of the a pawn is a sight to behold and perplexing to black.
