technique of converting an advantage. It was played in the last round, and we

{Despite the fact that there were a lot of decisive games this round, I
decided to actually pick this interesting draw in the match between India and
Russia. This was a Board One matchup between India's Vidit Gujrathi and
Russia's Peter Svidler. This was a very tough fighting match, which really
India probably feels like they could've also won with some good breaks. This
keeps Russia in the fight for the gold medals and guarantees them at least a
Bronze Medal no matter what happens in the last round. China won a relatively
one-sided match against Norway, which is why I decided to choose a game from
the India-Russia match. This game I found the most intriguing since White
played very nicely, putting a lot of pressure on his very strong and
experienced opponent, but then Svidler escaped after he found some strong
practical chances and Vidit failed to find a quite beautiful study-like win.}

{After his win in Chennai, Magnus took a 2 month break from chess, discounting
an indeed effective, yet rather risky attacking victory against Bill Gates.
The prolog in Zurich was a 5 round blitz tournament to determine the pairings.
Despite his actually winning it did indicate some rustiness in the champion's
play, but in his first classical game as World Champion, we saw Magnus from
his absolutely best side.} 1. c4 g6 2. d4 $5 {Having given it a shot at
avoiding the Grьnfeld, Magnus reacts to Gelfand's surprising 1...g6 by
actually allowing it! It might seem inconsistent, but one of Magnus' many
strengths is huge flexibility and not being dependent on a specific opening
choice.} Nf6 3. Nf3 Bg7 4. g3 c6 5. Bg2 d5 6. Qa4 $5 {An interesting line,
which became popular after Magnus used it to get a decent position against
Peter Svidler in Linares 2007. The inspiration then came from leafing through
Larsen's book ZOOM (Zero hour opening models). As Gelfand has mentioned it as
a book with a huge impact on his chess development, I guess hoping for 6.Qa4
being a surprise is too much, but even objectively it's an interesting line.}
O-O 7. O-O Nfd7 $5 (7... Bf5 {was what Svidler played, but after:} 8. Nc3 Nbd7
9. cxd5 Nb6 10. Qb3 Nfxd5 11. Rd1 Qd6 12. Bd2 Nxc3 13. Bxc3 Qe6 14. d5 $5 {
Magnus had a pleasant edge, as after exchanging on g7 and Nd4 White gets back
the pawn with risk-free pressure.}) (7... a6 8. Bf4 Be6 9. cxd5 cxd5 10. Qb3
Ra7 {was Aronian's creative way of handling the position im Monaco 2011, but
there too Magnus had a pleasant position, despite both games eventually being
drawn.}) (7... Nbd7 8. cxd5 Nb6 {has also been played, but the claim is that
after ...cxd5 the knight would rather be on b8, ready to go to c6, than sort
of misplaced on b6.}) 8. Qc2 Nf6 $5 {A very interesting novelty.} ({Against
Fressinet Gelfand had an unpleasant position after} 8... dxc4 9. Qxc4 Nb6 10.
Qc2 Na6 11. Rd1 {, but as always had done his homework well and has an very
interesting idea in mind, which made Magnus think for more than half an hour.})
9. Bf4 $5 {Probably White's best way to fight for an opening advantage. The
position after 8...Nf6 had previously occurred in quite a few games, but
always with Black to move! But in some way, White is actually in some kind of
zugzwang. The natural 9.Nc3 is answered by 9...dxc4 when its not obvious how
White gets his pawn back, and 9.Rd1 Bf5 10.Qb3 Qb6 already threatens 11...Qxb3
followed by 12...Bc2.} Bf5 10. Qb3 Qb6 11. Nbd2 Ne4 $5 {Nothing seems wrong
with 11...Nbd7, but Gelfand tries putting pressure in the centre and keeps the
option of putting the knight on c6, should White exchange on d5.} 12. e3 (12.
cxd5 Qxb3 13. Nxb3 cxd5 {[%cal Gb8c6] illustrates exactly that point, when
Black due to the knight coming to c6 is completely fine, so Magnus has to try
and keep the tension.}) 12... Qxb3 13. axb3 Na6 14. cxd5 cxd5 {A seemingly
dull position with no advantage for White would be the obvious conclusion.
Quite similar to Magnus' game against Caruana later in the tournament. And in
both games after just a few more moves, almost like by magic, suddenly Carlsen
has an overwhelming initiative.} 15. g4 $1 {An excellent move, with a good mix
of objective merits and provocation. Gelfand, being a principled player, of
course reacts with the critical continuation, accepting the sacrifice.} Bxg4 (
15... Nxd2 16. Nxd2 Be6 {was possible, but apart from the natural 17.Rfc1 Rfc8
18.Rc3!? also 17.Nb1!? keeps putting pressure on the black position.}) 16. Nxe4
dxe4 17. Nd2 f5 {The price Black has to pay for winning the pawn, is that his
bishop on g4 now is shut out, and can't help in defending the weak black
queenside.} 18. f3 e5 $5 (18... exf3 19. Nxf3 {illustrates well White's idea.
He is a pawn down, but his bishops points at the queensinde, and Black seems
not to be able to defend b7, when White's knight goes to either e5 or g5.
However there seems to be a hidden defence:} Rad8 $1 20. Ne5 (20. Ng5 e5 $1 21.
dxe5 Rfe8 22. Bxb7 Nb4 {is indeed a very computerish line, but Black seems to
generate enough counterplay just in time.}) 20... Bxe5 21. Bxe5 Rd7 {and
allthough White definitely still has sufficient compensation, Black's position
does seem very solid keeping the game in balance.}) 19. dxe5 exf3 20. Nxf3 Rae8
{Gelfand's play as always follows a clear logical path, and by sacrificing
back the pawn, it seems like he has neutralised the pressure of White's
bishops.} (20... Rfe8 {wouldn't be an inprovement, as} 21. Nd4 {attacking b7,
then caused trouble, but now this can be met by 21...Bxe5 22.Bxb7 Nb4 as there
is no longer a rook hanging on a8.}) 21. Ra5 $1 {It almost seems like White
goes to great lengths to hang on to his extra pawn, but it's actually equal
material, and White developing his initiative! Yes, he does have seemingly
weak doubled pawns, but like this Magnus defends the pawn on e5, thus being
ready for Nd4 or Ng5 very much making it a tactical battle, and not a quiet
positional game.} Nb4 22. Nd4 b6 23. Rxa7 Bxe5 {Again, Gelfand's play is
consistent and logical. Pushing away the white rook, he eliminated the pawn on
e5, and the knight on b4 controls the d5-square, keeping White's bishop from
checking on d5. A first sight, it would seem Black has solved his problems.}
24. Bh6 $1 Rf6 {An uncomfortable necessity, allowing White access to g7, but
the more obvious looking} (24... Rf7 {is answered very strongly by} 25. Ra4 Bd6
26. Rfa1 $1 {when defending against 27.Ra8! with a white mating attack becomes
very difficult, with White already being close to winning.}) 25. h3 (25. Ra4 $5
{would also have been very interesting, and maybe even better than the game
continuation. It's based on the tactical point} Bd6 26. Nb5 Bc5 27. Nc7 Rd8 28.
Rxb4 $1 Bxb4 29. Nd5 {when surprisingly despite being an exchange up, there is
no way only to sacrifice it back, as 29...Be7 would just be captured, and 29...
Rxd5 30.Bxd5+ Kh8 31.Ra1! wins further material due to the mating threat.} Rfd6
30. Nxb4 Rd1 {still do keep some drawing chances for Black though.}) 25... Bh5
$6 {Hard to believe, but this retreat weakens f5! Resolute defence with} (25...
Bxd4 $1 26. exd4 Be2 27. Rc1 g5 $1 {would come close to saving the game for
Black. The most tempting move looks to be} 28. Rg7+ Kh8 29. Re7 $1 {but after}
Rg8 30. Bxg5 Rxg5 31. Rc8+ Rg8 32. Rxg8+ Kxg8 33. Rxe2 {although White is
still considerably better, I would think Black has as good chances of saving
the game, as White has of winning it. The b-pawn is not much of an extra pawn
and ...Kf7 and ...Rd6 a solid setup making it very hard for White to break
through.}) 26. Nc2 $3 {An excellent tactical resource, illustrating that the
position despite the exchanged queens in no way resembles an endgame, but that
king safety is the dominating factor. By offering Black a chance to take on c2,
Magnus wins access to the d5-square for his bishop, and the direct acceptance
of the sacrifice leads to: 26...Nxc2 27.Bd5+ Rfe6 (27...Kh8 28.Bg7 is mate!)
28.Rc1 wins the knight, leaving White with an extra exchange, as 28...Nb4 29.
Bxe6+ Rxe6 30.Rc8 mates.} g5 $1 {The only way to fight back, challenging the
bishop on h6 just in time as now the black knight still controls the d5-square.
} 27. Bxg5 Rg6 28. Rxf5 $1 {This was the whole point of 25.h3. The black
bishop had to be lured to h5, leaving the f5-pawn unprotected.} h6 29. Bxh6 $5
{Keeping true to the style of the game, but actually the more modest} (29. Nxb4
$1 {might be objectively better as after} Rxg5 30. Rxg5+ hxg5 31. Bd5+ Kf8 (
31... Kh8 32. Bf7 Bxf7 33. Rxf7 Bxb2 34. Nd5 {also should win easily as White
will just bring up his king with decisive effect}) 32. Nc6 Bxb2 33. Kf2 {
Despite White being only one pawn up, he here has a dominating grip on the
position, and should win rather trivially.}) 29... Rxh6 $2 (29... Bf3 $1 {
amazingly prolongs the resistance. The point is that after 30.Rxf3 Nxc2 the
bishop on h6 is hanging, and ...Ne1 a threat, so White has to play} 30. Rg5
Rxg5 31. Bxg5 Bxg2 32. Nxb4 Bxh3 33. Nd5 {keeping good winning chances, but
not as easy a task, as after 29.Nxb4!}) (29... Nxc2 30. Rxh5 {Now the bishop
on h6 is protected, and} Ne1 31. Rg5 $1 {Just wins.}) 30. Nxb4 Bxb2 31. Nd5 Kh8
32. Rb7 Bd1 33. b4 Rg8 34. Ne7 Rd8 35. Be4 Bf6 $2 {In time trouble Gelfand
blunders, but even if it would take some time, White's extra pawns would
suffice for a win.} 36. Rxb6 Kg7 37. Rf2 $1 {Threatening 38.Nf5+ and if 37...
Bxe7 then 38.Rg2+! forces the black king to leave the protection of the rook
on h6, so Gelfand resigned.  An excellent start for Magnus, and while not
exactly without further adventures he kept up the pace and with 4/5 in the
classical control improved on his own rating record as well as gaining a huge
lead before the final rapids, when even a rather unstable performance sufficed
to give him a win in the overall standings too.} 1-0
