Tematurnering med Nimzoindisk etter 4.f3

Førstkommende torsdag kl 1830 er det duket for vårens tematurnering. Det spilles seks runder. Betenkningstiden er 10 minutter på hele partiet pluss fem sekunder per trekk. Det er sort som begynner å trekke i tematurneringen denne gang. Utgangsstillingen oppstår etter

      1. d4     Sf6
      2. c4     e6
      3. Sc4   Lb4
      4. f3

4.f3

Magnus Carlsen har møtt denne varianten i Nimzoindisk i tre viktige partier siste halvåret og vunnet alle tre, men har kommet dårlig ut i alle: I VM-matchen mot Anand i november og to ganger mot Nakamura (Zurich i februar og Gashimov nå nylig.) 4. f3 er logisk. Hvit ønsker å spille e4 neste trekk. Trekket er det fjerde mest populære mot nimzoindisk, men er det som scorer best for hvit.

names according to who you ask – including Gheorghiu Variation, Shirov
Variation and Kmoch Variation – is a sharp way of meeting the Nimzo and has
been on the spotlight recently.} c5 (4… d5 {Nakamura-Carlsen Zurich}) 5. d5

himself against Le Quang Liem in 2011.}) 8. Nge2 Ne5 9. Ng3 exd5 10. cxd5 {We
are now relatively out of opening. The position resembles a Benoni except that
Black’s bishop is all the way out on b4 instead of on g7. This has some good
things and some bad things. Mainly good is the fact that the bishop can
re-route to the g1-a7 diagonal which is quite exposed.} Bd7 11. a3 Ba5 12. Be2
b5 13. O-O c4 {Black is very quick about activating his counterplay. White
aims at neutralizing this and counterattacking when all his pieces are placed
properly.} 14. Be3 Bb6 15. Qd2 Rb8 16. Nd1 Bc8 17. Kh1 Nfd7 18. f4 Ng6 19. Bxb6
Rxb6 {Both sides are maneuvering to improve their pieces. White has achieved
f4, kicking out the knight from f4, meanwhile Black has established his b5-c4
pawn chain and hopes to reinforce it with a powerful knight on c5. Both sides
have interesting chances. Black will seek to pressure e4 while advancing his
queenside pawn chain. White seeks to create kingside pressure while
undermining Black’s position in the other flank.} 20. Ne3 Nc5 21. Bd1 Nd3 22.
f5 $5 {Quite aggressive. Nakamura uses the fact that the knight cannot really
go back to e5.} Ngf4 (22… Nge5 23. f6 $16 {lands Black in serious trouble.})

at least worth consideration, but it is not an easy move to play.} Nxf4 (25…

compensation, though it’s hard to say over the board how much that is, further
analysis seems to show it is too much for Black to retain all of his material.}

Rb7 28. Nxh5 Qh6 29. Qxh6 gxh6 {White has emerged up a pawn, but Black retains
very serious compensation. His knight on d3 is quite powerful and with the
queens off the board the knight on h5 looks rather silly. If White can
consolidate he will still have a rough time trying to push his pawns forward.}
30. axb5 axb5 31. Bc2 $5 {Not one to sit back passively, Nakamura aims to
create kingside play at the cost of his queenside.} Ne5 $5 {Seems passive, but
it does not allow counterplay.} (31… Nxb2 32. Rf3 b4 33. Rg3+ Kh8 34. Ra6 $5
{Is a very hard to assess position. Carlsen must have been afraid of something
like this, in which White sacrifices his bishop for two pawns but retains
control over the rest of the board.}) 32. Ra6 Rd8 {Somewhere starting now
Nakamura starts to go wrong. Maybe bringing his knight back was not the best
idea, and it was more important to simply secure the a-file by doubling on it.}

the idea the Aronian brings to the table is interesting and exciting.} 11. Qe2

It is uncomfortable to face this in a real game, over the board.} 12. fxg7 {
Mamedyarov didn’t think too long before accepting the challenge head on.} Re8
13. Be3 Nc6 {Objectively speaking it is difficult to find a move for White.}
14. Qd2 $1 {A good practical decision.} (14. f4 $5 {Has the idea of quickly
playing Nf3 and Ne5, but this is not so easy.} Nb6 15. Nf3 Bg4 $1 {and already
there are too many threats to defend against.}) 14… Na5 15. Rb1 Nb6 16. Rb4 {
White is sacrificing the exchange but it will Mamedyarov that has the
compensation. With both kings being unsafe and Black’s structure being
questionable the position is very hard to evaluate.} Nac4 17. Bxc4 dxc4 $5 {
Interesting but not the strongest.} (17… Nxc4 18. Rxc4 dxc4 19. Kf2 Bf5 $13 {
is simlar to the game but the queen is not so exposed on d5.}) 18. Rb5 Bf5 19.

really wanted the material, instead they wanted to play with the initiative.}
Nd5 20. Ne2 Rxe5 21. dxe5 Re8 $13) 19… Nd5 20. Rxd5 Qxd5 21. Ne2 {The
players reached the position in which Black is up an exchange anyway. Here it
is very difficult to evaluate or even give a plan for either side. However
Aronian’s venture was less than successful.} a5 $2 {The start of a wrong plan.
I initially liked this idea but it is far too slow and far too ineffective.}
22. h4 b5 23. h5 {Mamedyarov tries to force Aronian into taking on g7, which
will weaken his king permanently. On the other hand, if he doesn’t take h6
might seal a decisive passed pawn.} b4 24. cxb4 axb4 25. axb4 Qb5 {Black has
managed to open some files, but it is unclear what exactly he accomplished by
doing so. Also bad news for Aronian was his time situation; he only had about
15 minutes left by this point to make the remaining 14 moves.} 26. Re1 {Normal
development is sound and strong. It is possible to spend a long time
calculating alternatives, but I like Mamedyarov’s approach.} Bd3 27. Nf4 Ra3
28. d5 $1 $18 {A very important move. With the bishop coming to d4 White will
threaten all sorts of mating attacks against the king. Also important is the
fact that now e6 is defended for the White knight.} Bb1 $5 {Tricky, but
Mamedyarov finds a precise response.} 29. Kg3 $1 {The computer spout some Qd4
move, but pay no heed. This move is accurate and easy.} c3 30. Qc1 $1 {
Extremely strong.} (30. Qd4 {is probably also winning, but it requires
calculation.} c2 31. Ne6 $1 Rxe3 $1 32. Qf4 $1 (32. Qxe3 Qxd5 $13) 32… Qb8 $8

Mamedyarov’s method is good enough.} Bf5 {Nh5 has to be stopped obviously.} 35.
Nh5 $3 {is a ridiculous computer win} (35. d6 {is more natural. The pawn
cannot be taken because Qd6-f8 would be unstoppable, so Black is completely
lost.} c2 36. Nh5 Qxh5 37. Qd5+ Qf7 38. Qa8+)) 34… Bg6 35. Qe8+ Qxe8 36. Nf6+

obvious win, White has too many pawns and too many of them are passed.} Bd3 42.

this endgame is a known draw} 50. b7 Bxb7 51. Kxb7 $11 {White cannot make
