Black’s pawns on c5 and e5 (the
so-called Maroczy Bind) give him a pleasant space advantage, but White
is well developed and his last move threatens to destroy Black's
queenside structure with Nd4. Watch how Black effectively clears
the h1-a8 diagonal.
10. …Qe6!
Preventing White’s
threat.
11.Nd2
Or 11.Qb3?!
And now:
A) 11...Qxb3
12.axb3 gives White a doubled b-pawns, but the half open a-file is
useful, for example 12.…Bd7 13.Rfc1 b6 14.b4! cxb4 with a small but
useful initiative.
B)
11.…Rb8! (Black continues to vacate) 12.Rfc1 b6 13.Qxe6 Bxe6 14.Ng5 Bcg5
15.Bxg5 Nd4 16.Kf1 f6 17.Bd2 a5! And Black is fine.
Andersson –Tilman, Tilburgh 1987. The bishop on g2 simply stares
into a vacuum.
11. … Rb8!
A second piece is
removed from the diagonal. Black prepares to support his c-pawn
with … b7-b6
12.Ne4 b6 13.f4
If White doesn’t
strike back, then Black will catch up in development and retain a space
advantage.
13. … f5 14.Nc3
Kh8!
Vacating another
diagonal (a2-g8.) Now Bd5 is no longer a worry.
15.Qa4
15. … Bd7!?
In his note in
ChessBase Magazine, Chuchelov gives the worthwhile alternative 15.…Bb7!?
16.Bd5 Qd6 17.Bxc6 Bxc6 18 fxe5 ( 18.Qxa7? loses after 18.…Ra8 19.Qxb6
Rfb8 20.fxe5 Qe6 21.Qc7 Rb7 and the queen is trapped) 18.…Qxe5 19.Bf4
Qe6 20.Qxa7 Rb7 21.Qa6 Bf6 22.Rae1 g5 23.Bd2 f4, after which has
excellent play for the pawn disadvantage. Note that in this
variation the long h1-a8 diagonal is now firmly in Black’s possession!
16.fxe5 Nxe5
17.Bd5
17.Qxa7? Loses to
17.…Nc6 18.Bxc6 Qxe3+ 19.Rf2 Bxc6
17...Qd6 !
17.…Bxa4 18.Bxe6
Bd7 19.Bxd7 Nxd7 is equal but Black plays for more.
18.Qd1?! Bf6
Black has removed
all his pieces from the h1-a8 diagonal and the bishop on d5 is rather
less effective. Black is clearly better now. His position is
more compact and white may have problem defending down the central
files.
19.Bf4 g5
20.Bxe5 Bxe5 21.Bg2 Bd4+ 22.Kh1 f4 23.gxf4 gxf4 24.Qe1 Rbe8
Now White has
problem with his weak e2-pawn.
25.Rc1 Qh6!
Intending to play …
Rg8 and … Bh3. White is in big trouble now, but his next move,
influenced by time trouble, makes sure that the end is quick.
26.Nd1?? f3!
The rook on c1 is
hanging.
27.Rxf3 Rxf3 0-1
