White to move.

*************************************************************************
White to play - from this position! {Given above} ********************* White seems to be solidly better here, yet Black's Queen is all set to go on a raiding party on the Q-side. How does White proceed from this position? |
**************************************************************************************
This position is derived from the contest:
GM Thomas Ernst
(2441) - NM Jorgen Eriksson (2234);
[C12]
ICT, The Rilton Cup 2006-7 / Stockholm, SWE; (R8) / 04,01,2007.
****************************************
25.Qf3!!,
There are many ideas for White in this position, but this is the best.
(The solution is many moves deep, some programs do not grasp the solution here.)
White has many threats, both f7 and d5 are hanging.
25...Kc7;
Black tries to extricate his King.
[ Even worse would be:
</= 25...Qb2?!; ('?') 26.Rxf7+ Bxf7;
27.Qxf7+ Ne7!?; 28.Re1 Ra6; 29.Nf4, "--->"
when White's assault has reached alarming (and also winning)
proportions. ]
26.Rxf7+!! Bxf7;
27.Qxf7+ Qe7;
This appears to be virtually forced for Black.
[ After the moves: </= 27...Kb6?; 28.Bxe6 Rhf8;
29.Qxg6, "+/-"
Black's position is on the verge of falling apart.
]
The next few moves are pretty
much forced ... for both sides.
28.Qxe6 Qxe6; 29.Bxe6 Ne7; 30.Nf4 Kc6; 31.Bf7!,
I like this best, White does not mess around, but immediately "gets busy" on the King-side.
[ The box seems to prefer: 31.Ke2!?, with the idea of bringing the WK all the way over to d2. ]
31...Rhf8;
32.e6 b4;
Black tries to pry open a file for his Rooks. (This is a good idea, at least in theory, as the Black
heavy pieces currently have almost no scope at all.
33.Nxg6 Nxg6;
34.Bxg6 Kd6; 35.Re1 Ra7!?; (An error?)
The advantage (for White) practically doubles after this move, its main drawback is
that it was too materialistic.
[ Black should have played:
>/= 35...Rf6; which is an offer to
return the material ... IF White pushes his KP after ...Rf6. ]
36.Bxh5 bxc3;
Black continues on as planned ...
[ Another idea here was 36...Rh8; trying to activate the Black KR. ]
37.Bf7 Rb8;
38.g4 Rb2; 39.g5 Rxc2; 40.g6 Rd2?!; ('?')
This loses rapidly, the box suggests (instead) that Black play 40...Ke7; with the idea of bringing the
Black King over to help stops the advance of White's infantry. (However, even with correct play, Black will not be
able to avert a loss from this position.)
The rest is pretty simple.
41.g7 Ra8; 42.e7 c2; 43.g8Q Rxg8; 44.Bxg8 Rd1!?;
45.e8Q c1Q?;
Too obvious - Black had to swap Rooks on e1, (with check); and then promote his Pawn, giving check.
(I am not sure, but time might have been a factor here.)
46.Qd8+ Kc6;
47.Qxd5+ Kb6; 48.Qc5+ Kb7; 49.Bd5+, "+/-"
Black Resigns, its mate in just two more moves from here.

*************************************************************************
Black to play - from this position! {Given above} ********************* It has been an extremely complex struggle thus far, and right now the game looks close to being equal. Now the second player comes up with a series of ideas ... that not even the computer is able to grasp fully. |
**************************************************************************************
This is derived from the contest:
GM Peter Leko (2749) -
GM Viswanathan Anand (2779);
XXIV SuperGM, (Round # 07)
Morelia/Linares, MEX/ESP; 25,02,2007. [replay]
26...Be5!;
This is the best ... the Bishop is re-activated, and White's responses are pretty much forced ... in order to
avoid losing material.
27.Qg8+ Qf8;
28.Qxf8+ Kxf8; 29.Rc1 Bf5; 30.e4,
Positionally speaking, this is forced, White cannot allow Black's Bishop access to the d3-square.
30...Bh7;
31.Bb6 Bf6; 32.h4!?,
Somewhat adventurous, but it is not so easy to play White's position from this point.
[ After the continuation: (>/=) 32.Re2 Be7; 33.Ba5 Ra8; 34.f4
c5;
"=/+"
Black is better, but perhaps this is an improvement over the game.
]
Black's next move looks like an
obvious capture, however, you have to (try) and understand ... the second player has already decided to sacrifice
some material.
32...Bxe4!!; 33.Bh3 Bd5!; 34.Bxe6 fxe6!; 35.Bc5+ Be7;
36.Bxe7+ Kxe7;
Now it appears that all Black has managed to do is drop an exchange.
(Don't change that channel!)
37.Rb2 Kd6!;
38.Kf1 c5!; 39.Ke2 cxb4; 40.Rxb4 Kc5; 41.Rcb1 Bc6;
"/+" Leko RESIGNS!!
The talented Hungarian super-GM knows that once Black's connected passed Pawns start rolling on the
Queen-side, the loss is certain, and only a matter of time. (All that is needed is for Anand's Rook to join the party.)

*************************************************************************
Black to play - from this position! {Given above} ********************* Sometimes in high-level
chess, what is required is not a brilliant win; but tough, stubborn
and obdurate |
**************************************************************************************
This is derived from the struggle:
GM Peter Leko (2738) -
GM Vladimir Kramnik (2772);
[C88]
Rapid Match / Miskolc,
HUN; (R#2) / 25,04,2007. [Replay
... the whole game.]
*************************************************
GM V. Kramnik, who seems to be almost unbeatable as of late ...
shows us how it is done.
33...Qxc4!;
34.Rc1 Qxc1!;
Only with this move ... the positional sacrifice of the Queen ...
does Black clearly demonstrate that he can hold the draw.
[ Instead, after the continuation of: </=
34...Qb5; 35.Rxc8, '±' (Maybe "+/-")
White looks close to having a won game here.
]
35.Bxc1 Bb6!;
36.Be3 Bxe3; 37.Rxe3 Nf6; 38.Qa4 e4!;
Rather than tie his pieces down to defense, Kramnik jettisons a pawn.
39.Qxa6 Rc1+;
40.Kg2 Rc2; 41.Re2 Rxe2; 42.Qxe2 Rxd5;
Materially speaking, the game is close to even. Normally, a Knight and a Rook are a poor substitute
for the Queen, but here Black ... with all the material on only five files ... has something of a fortress,
and manages to just cover all of his remaining weaknesses.
43.Qc4 Kf7;
44.Qc7+,
The only other option was to play f2-f4, but I doubt if that would have made much of a difference.
The remaining moves require
no further comment from me.
44...Ke6; 45.Qc8+ Ke7; 46.Kf1 Rc5; 47.Qb7+ Ke6;
48.Ke2 Rf5; 49.Qc8+ Ke7;
50.Qc7+ Ke6; 51.Qc8+, (Draw)
Spirited defense from Kramnik, who managed to save a position that appeared perilous at one time in this contest.

Black to play - from this position! {Given above} ********************* Play now proceeded: 30...Bc8?!;

**************************************************************************************
This is my "Problem of The Month" (Site Chess Problem) for July, 2007.
This is all based on the game:
GM Daniel Stellwagen (2600) - IM Manuel Bosboom (2423); [B08]
National Championship Tourn. (ch-NED) / Hilversum, NED; (R#3) / 18,06,2007.
Play now proceeded:
30...Bc8?!; 31.Rb4! Kf7?;
and now White wins with a nice combination ... and some accurate play in the ensuing endgame.
32.Bxa6! Nf3+;
33.gxf3 Rxa6; 34.f4 Bd7; 35.Kg2 Kf6; 36.Kf3 Rac6;
37.Rd1 Rxc3+; (A desperate bid for counterplay.) 38.bxc3 Rxc3+;
39.Rd3 Rxc2;
40.Ra3 Bc6; 41.Ke3 e5; 42.fxe5+ Kxe5; 43.a5 g5; 44.a6 h5;
45.a7 Ba8;
46.Ra5 Rc3+; 47.Kd2, "+/-" Black Resigns.
Black throws in the towel, the position after 47...Rc8; 48.Rb8, offers Black no chance to save his game.
