1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. e3 ({This came as a surprise. My opponent
usually goes} 4. Nf3 dxc4 5. a4 Bf5 6. Ne5 {when most lines lead to a tactical
fight that suits well an attacking player. However, I was going to avoid that
kind of stuff, relying on chess catenaccio i.e. the line} e6 7. f3 c5 8. e4 Bg6
9. Be3 cxd4 10. Qxd4 Qxd4 11. Bxd4 Nfd7 12. Nxd7 Nxd7 13. Bxc4 {that was seen
in the World Championship matches of Topalov (as White) against Kramnik (2006)
and Anand (2010). I had analysed this ending for several hours before I sat
against GM Shishkin. Critical lines reach as deep as move 30. Though he
avoided my preparation, the work was not in vain. I made use of it two rounds
later against IM Marcin Sieciechowicz (2454). The latter game followed:} Rc8

agreed to a draw.}) 4... a6 {Chebanenko System. I use it regularly against
e2-e3.} 5. Nf3 b5 6. c5 Nbd7 {The most principled response, though some
players prefer 6...g6, which leads to a cramped position.} 7. b4 ({The main
line is} 7. Bd3 {Surprisingly, it led to a short disaster for White,
administered to no other than the current World Champion:} e5 8. Nxe5 Nxe5 9.

Memorial, Moscow 2009. This game shows the dangers that await White if he
plays carelessly.}) ({Other White's options are} 7. a3) ({and} 7. Bd2) 7... a5
8. bxa5 Qxa5 {The idea is to follow with b4 and Ne4 in order to spoil the
harmony in the White camp.} ({Worse is} 8... e5 $6 {that was played in
Dreev-Korotylev, Russia 2004. After} 9. Bd2 e4 10. Ng1 Rxa5 11. a4 bxa4 12.
Rxa4 Rxa4 13. Qxa4 Qc7 14. Na2 Be7 15. Nb4 {White achieved a position of his
dreams. The a- and b- files are open and Black is in big trouble due to the
weak c6 pawn and bad white-squared bishop.}) 9. Bd2 b4 10. Nb1 ({It is likely
that} 10. Ne2 {is more accurate, e.g.} Ne4 11. Nc1 Nxd2 12. Qxd2 e5 13. Nb3 Qa4

a strong tactics.} ({In his youth, one well-known French magician played here}

I can recapture the sacrificed piece thanks to the double attack on Ra1 and
Be2. My play can seem a bit risky given that I have not castled yet, and the
e-file is open. However, White's pieces are so poorly coordinated that they
are not able to take advantage of the above circumstances.} 18. Ra2 ({Probably,
White could do better by sacrificing a pawn for activity:} 18. Bb5 $5 {However,
after} cxb5 19. Ra2 Bxc5 20. Nf3 Qd6 21. Re1+ Be6 22. axb4 Rxa2 23. Qxa2 Bb6 (

not only poorly developed, they have no future since they cannot find any safe
harbour in the centre.} 21. Nc3 {From now on I make several moves that gain
tempi.} Qd3 22. Ndb1 Bf6 23. Rd1 Re8 24. h3 {The king needs the h2 escape
square, but the text move weakens White's position further.} Qg6 {Gaining
tempo again: 25...Bh3 is threatened.} 25. Kf1 d4 26. Ne2 Be6 27. Qa6 Bd5 28. f3

weaken his position I find a perfect outpost for my bishop.} 36. Qa4 Re2 0-1
