start the struggle for centre.} 4. cxd5 Nxd5 5. Bg2 {[%cal Rc3d5,Rg2d5] White
joins in this struggle too, but so far only by pieces, the pawns remain
motionless.} Nc7 {[%csl Rd4] The Knight retreats to a somewhat unusual
position. But from there it can be thrown over to the d4-square. Just this
square becomes the main target for Black.} 6. Nf3 Nc6 7. O-O e5 {Continuing to
seize the central squares by pawns. Black's plan is to create two pawn chains
- a7-b6-c5 and g7-f6-e5 - and then to besiege the d4-point.} 8. b3 {One of the
playing plans for White in such positions is to press on the c5-pawn with a
subsequent offensive on the Queen side.} Be7 9. Bb2 O-O 10. Rc1 f6 11. Ne1 ({

developing to f5. For example:} 11. Nh4 Qd7 12. Na4 Rd8 (12... b6 13. b4 $1)

weaknesses for counterplay in his camp.} ({In this sense it was better to give

"height".} 21. Nc3 Nb4 {Botvinnik wrote about this position the following:
"Black has reached an ideal piece and pawn disposition. His Knights are
located almost inaccessiblely because a3- and e3-moves would only weaken
White's position in a fatal way".} 22. Nf3 $2 {Leads to a fast loss.} ({Better

1. d4 d5 2. c4 Nf6 $6 {A well-known inaccuracy that leaves the centre in
White's hands.} ({If Black is aiming for the Queen's Gambit Declined, he
should play} 2... e6 {first.}) 3. cxd5 $1 Nxd5 4. e4 Nf6 5. Nc3 e6 $6 {This
leads to a rather cramped game.} ({After} 5... e5 6. Nf3 exd4 7. Qxd4 Qxd4 8.
Nxd4 Bb4 9. f3 {White has also had good results in practice, but Black enjoys
more activity than with the text. Anyway, by playing 4 Nf3 first White could
have sidestepped that line.}) 6. Nf3 Be7 7. Bd3 O-O 8. O-O a6 ({Unfortunately
for Black,} 8... c5 $2 {runs into} 9. dxc5 Bxc5 10. e5 Nd5 11. Bxh7+ $1 Kxh7
12. Ng5+ {with the Greek gift working perfectly.}) ({The text prepares ...
b7-b5, but the modest} 8... b6 {, followed by ...Bb7, was probably more to the
point, speeding up development and exerting some pressure on the h1-a8
diagonal.}) 9. Qe2 $1 Nbd7 10. Rd1 {Such a set-up is often used in similar
positions in the Queen's Gambit Accepted. On e2 the queen avoids exposure to
the black pieces and enables the attacking idea e4-e5, followed by Qe4, while
the rook on d1 discourages Black's ...c7-c5.} c6 {Again very passive;} ({but
the desired} 10... b5 {ran into} 11. e5 Nd5 12. Qe4 $1 f5 13. exf6 N7xf6 14.
Qh4 {with a huge edge.}) 11. Bg5 Re8 12. Rac1 h6 13. Bh4 Nf8 {Time for White
to convert his central control into something more tangible.} 14. e5 $1 {A
typical idea. In exchange for weakening the d5-square, Grabarczyk manages to
swap Black's "good" bishop, something that will yield him a grip on the dark
squares and, indirectly, attacking prospects on the kingside.} Nd5 15. Bxe7
Qxe7 ({Or} 15... Nxc3 16. Rxc3 Qxe7 17. Nd2 $1 {with similar play.}) 16. Ne4 $1
Nf4 {This exchange doesn't help Black's case in any way, but it was already
difficult to give him good advice.} 17. Qe3 Nxd3 18. Rxd3 Rd8 19. Nfd2 $1 ({
White doesn't even want to allow} 19. Nd6 Rxd6 $1 20. exd6 Qxd6 {, so directs
the other knight to d6 as well.}) 19... Ng6 20. Nc4 Qc7 21. Ncd6 {In strategic
terms, the game is already over - Black will never be able to get rid of that
knight, which deprives him of any counterplay and makes White's kingside
attack child's play.} Ne7 22. Qf4 Nd5 23. Qg4 Qe7 24. Rf3 Rf8 25. Nf6+ $1 {
Enhancing the attack and eliminating any attempts at ...f7-f5.} Kh8 26. Qh5 Rb8
27. Re1 $1 {The last piece joins the party with devastating effect.} Bd7 28.
Re4 Nxf6 29. Rxf6 Kh7 30. Rh4 $1 Qxf6 31. exf6 Rh8 32. Qxf7 1-0
