WHITE TO MOVE
This is new move, but there
is no idea behind this move. 10.e4 White develops easy an initiative.10...Ge7
[ If 10...e5?! then11.g5 Sh5? 12.Sxe5±]
WHITE TO MOVE
11.g5 Interesting variation could
occur after 11.e5 Sd5 12.Sxd5 cxd5 13.Gd3 h6 14.h4 Gb7÷ Black has counterplay
with f7-f6
Vary dangerous is to play
15.h5 f6 16.Sh4
BLACK TO MOVE
Position looks very
unclear, but probably black is doing very well. 16...Wc8! 17.Hb1 Interesting
was to play 17.Gh7+ Kh8
18.Sg6+ Kxh7 19.Sxf8+ Kg8 20.Hh7+ Kxf8 21.Gxh6 Ha5+ 22.Kf1 gxh6 23.Hxh6+
Ke8 24.Hg6+ Kd8
WHITE TO PLAY
25.h6 ( if 25.Hg8+ then
25…Kc7 26.Wc1+ Gc5 27.Hxe6 Gc6 28.dxc5 Hd2 and black has strong initiative)
25...Hd2 26.h7 Kc7 27.h8H Wxh8 28.Wxh8 Hxd4÷) 17...Wxc1+! 18.Hxc1 fxe5
19.Sg6 black has advantage.
Back to the game: 11...Se8
12.Gf4 Gb7 13.0–0–0 Sb6 14.Kb1
BLACK TO MOVE
14…a5 [14...b4 15.Sa4 Sxa4
16.Hxa4 c5 17.dxc5 Gxe4+ 18.Ka1 Gd5 19.Hxb4 Wc8 20.Wc1 f6 21.g6 hxg6 22.Whd1ƒ] 15.h4
[Second possibility for white was to play: 15.Gd3 b4 16.Se2 Wc8 with the
idea c6-c5] 15...b4 16.Sa4 Sxa4 17.Hxa4
BLACK TO MOVE
17…c5! Typical motive in the Meran
System. Here it is worth noticing that white will get a passed “c” pawn and the
question is: is it a strong or weak one?! 18.dxc5 Gxe4+ 19.Ka1
BLACK TO MOVE
19…Hc8?! It is not correct move. It
was necessary to cover "d" line. [19...Gd5 20.Gc4 Sc7 and it is not
so clear after: 21.Gxc7 (21.c6 Gd6 22.Gxd5 Sxd5 23.Ge5 Wc8) 21...Hxc7
22.Gxd5 exd5 23.c6 Wac8 24.Wc1 f6 25.Hb5 (25.g6!? hxg6 26.Whd1 (26.Hd1!?
with advantage for white) ) 25...Hd6 26.Whd1 fxg5 27.Sxg5 Gxg5 28.hxg5 Wxf2
29.Hxa5 Wf5] 20.Wc1 f6
WHITE TO MOVE
Position became suddenly
quite tactical now. We looked at a lot
of moves but 21.g6!! is the best.
BLACK TO MOVE
This is an unusual move but
quite logical: for a pawn white is stopping black’s counterplay along the
"f" file and opening the "g" line for his own rook. It is
good to remember the old saying that to win you have to create a second weakness.
The c5 pawn is one thing black has to be worry about, now the second thing will
be his king. One exclam for 21.g6!! is for objective reasons - it is simply
very good move. The second exclam is for the original idea which is still far
from being discovered by the computer itself. 21...hxg6 Others moves
were possible:
21...Gxg6
22.Sd4 e5 23.Sc6 with advantage for white;
or
21...e5 22.gxh7+ Kxh7 and now after 23.Ge3:
BLACK TO MOVE
23…Hc6
24.Hxc6 Gxc6 25.h5 with better endgame for white
If 23…Hf5?
Then 24.Sg5+ fxg5 25.hxg5+ Kg8 26.Hb3+ Wf7 27.g6 Hxg6 28.Gh5 a4 29.Hc4+-
BACK TO THE
GAME:
WHITE TO
MOVE
22.Whd1! Bravo for this move for
Rybka engine! Human would be tempted to keep the rook on h1 to try to attack
black king. However Rybka suggested that the "d" file is far more
important due to the threat of Rd7 or Rd6. Black played: 22...e5 this
move opened a2-g8 diagonal for whites pieces. Other moves were no better for
instance:
22...Gd5
23.Hc2 a4 24.Hxg6 a3 25.b3 with advantage for white;
22...Sc7
23.Gxc7 Hxc7 24.Wd7 Hf4 25.Wc4 Wf7 26.Sd2 f5 27.Sxe4 fxe4 28.c6 with advantage
for white.
23.Ge3
BLACK TO
MOVE
23…Kh7?! This quite innocent looking
move is probably losing! After other moves white has a much better position for
instance:
23...Sc7
24.Rd7 We8 c6 with better position for white;
23...Kh8
24.c6 (24.Hd7!?) 24...He6 25.c7 Gd6 26.Gc5 Wc8 27.Gxd6 Sxd6 28.Sd2 with
advantage for white]
23...Gc6
24.Hb3+ and now:
BLACK TO
MOVE
24...Kh7?
25.Sg5+! fxg5 26.hxg5 Hb7 27.f3! and Rh1 with a winning position for white
or
24…Kh8 25.Hc2 and now:
25…Hf5 26.Hxf5 gxf5 27.h5 with a much better endgame for white
or
25...e4 26.Sd4 Gd5 27.Gc4!?±
BACK TO THE GAME:
WHITE TO MOVE
24.h5! Beginning of a nice
tactical combination. It looks like Intagrand did not have enough computer
power to see the coming blow. 24...gxh5 [24...g5 is hopeless due to:
25.Wd7 Wf7 26.Wcd1 Kg8 (26...Gc6 27.Hb3+-) 27.h6+-] 25.Wd7 Wf7 26.Gc4
BLACK TO MOVE
