{In Round 7 of the Millionaire Chess Open I was paired against a 2650 GM from
Russia, Aleksandr Shimanov. After winning a few games in a row I found myself
playing a much stronger player than I expected. Whatever preparation I had
done was useless once I saw my opponent's opening choice.} 1. d4 e6 2. Nf3 Nf6
3. Bf4 {The London System, feared by many because of.. how dull and annoying
it can be to play against. After Magnus Carlsen used this opening, with varied
success, it has become incredibly fashionable at all levels of play.} c5 4. e3

is the main line}) 6. h3 cxd4 7. exd4 b6 8. c3 Bb7 9. Bd3 O-O 10. O-O Re8 11.
Re1 d6 {There are many ways to play against this system, but I always try to
avoid playing ...d5, which gives White easy play with Ne5 and Ndf3.} 12. Bh2
Rc8 13. a4 Bf8 14. Nc4 h6 15. Bf1 Qd7 16. Nfd2 Red8 17. Bg3 ({I had intended
to meet} 17. a5 {with} b5 18. a6 bxc4 19. axb7 Qxb7 {but I missed the strong
continuation} 20. b3 $1 $16 {when} cxb3 21. Ba6 {is very good for White.})
17... Be7 18. Qb3 Na5 $1 {This move doesn't feel right, giving Black doubled
and isolated a-pawns, but it was the trap I prepared against White's natural
move Qb3.} 19. Nxa5 bxa5 20. Qb5 Qc7 21. Rac1 (21. Nc4 Bd5 $1 22. Nxa5 Ne4 23.
Bh2 Rb8 $19) 21... Bc6 22. Qc4 Nh5 {Taking advantage of White's 17th move and
activating the pieces with tempo.} 23. Bh2 Bg5 24. Rc2 Qb7 25. Qa2 Nf4 26. f3
e5 $1 {The last five moves have all come with tempo; Black's position is
improving with each move, but I was spending too much time to find the right
plan. Time pressure started to become a big factor around this point in the
game.} 27. dxe5 dxe5 28. Nc4 e4 $2 {Based on how badly White's pieces are
placed I assumed that any move to open the position would be in my favour, but
I commit an error in time pressure} (28... Bd5 $1 29. b3 Be6 30. Rxe5 Rd1 $15 {
with a big initiative for Black.}) 29. fxe4 Bxe4 30. Rf2 Nd3 31. Bxd3 Rxd3 32.
Nd6 Rxd6 33. Bxd6 Bd5 {With little time on the clock I am just trying to reach
move 40. The two bishops put up great resistance.} 34. Qb1 Bh4 35. g3 Qd7 $5 {
Diagram [#]Critical Position} 36. Bf4 $4 {My opponent played too quickly; and
surprisingly White is dead lost after this move.} (36. Qd3 $1 Qxd6 37. gxh4 $18
{by no means an easy conversion ahead, but White is definitely winning.}) 36...

easily winning.}) (41. Qd1 Bxe2+ 42. Rxe2 Qf3+ 43. Ke1 Qh1+ 44. Kd2 Rd8+ $19)

good fortune near the time control. Shimanov is one of the highest rated
players I've ever beaten, but despite a solid opening it took some help from
my opponent to win this one.} 0-1
