White plays 21.Bxb3 and Black moves 21....h5
White recaptures on b3. Black attacks the Knight on g4 in the hope that White places it on e5,which would be to blacks great delight. But also planning on the other response;22; axb5,which lead to intriguing possibilities. The move 21....Qc7 was exhaustively studied and has merit, but allows White much more counter play then with h5.

well....
White had anticipated 21....h5 for quite some time (as had klauno). Black's great delight of 22. Ne5 can unfortunately not be fulfilled, as much as I would like to please The only real possibility for white here is to break black's queenside constellation once and for all, which also opens up lines for bishops......I think this is really what both brigadecommander and klauno had anticipated

Unlike Klaus I visioned it the opposite way. 21.Bxb3 Qc7 22.axb4 Nd8 23. c4 dxc4. It still really isn't great for black at such a high level, but it is different.

@myevilluck
I agree. 21..... Qc7 is a good move (just as brigadecommander said). I think your sequence leads to a pretty level position, as does the the played alternative
|
|
i made notes
on the viability of 21....Qc7. They are as follows ;21...Qc7 22.axb5 Rxb5 23. Ba4 Rb6 24.c4 dxc4 25.Qg2 c3. 26.Qxe4 Rf5 etc. In my Opinion the game is almost level.

strongholds
the black pawn in the middle of the board may prove definitive after all?
|
|
you have a good eye bishop1000
the pawn structure or 'pawn skeleton' shows up weaknesses and strong/points for both sides.
|
|
White plays 22.axb5 and black moves 22....Rxb5
22....hxg4 was a serious candidate but it was determined that it leads to a more or less level position. In hxg4 Black would have to commit resources to her left flank, that would then have to be recalled again later on. The War will be decided on Blacks right flank.
|
|
Furthermore, 22. ... hXg4 leads to 23. hXg4 , opening the h file for the white queen
|
|
pitiroque
he would play 23.Ba4 i believe. Ask him.

I think you saw the board wrong, if 22. ... hxg4 then 23. bxc6 Bxc6 24. Bd1 .
|
|
no no no no
every one is missing white supernatural, camouflage, tricks and allusions at it's disposal
. Black pawn clogging middle should have been run over instead of going around.

if
22...axg4 then yes 23.bxc6 Bxc6 and if 24.Bd1 then Black plays 24...gxh3. And if then 25. Qxh3 then Black plays 25...Rf6. If white plays instead plays
25.Rf2 then black again plays 25....Rf6. This is the diversion of forces i spoke of before. This Rook will have to return sooner or later to the other flank. Yes Black still has advantage but i believe 22...Rxb5 leads to a more concrete one.
|
|
correction
that is 22....hxg4 not axg4.

@ptitroque
no, 22.....hxg4 had led me to play 23. bxc6. Any other move (such as 23. Ba4 or 23. hxh4) had led white to lose a piece (the knight) without compensation.

after black's Rxb5
white's knight at g4 is still hanging, and white's bishop at b3 is now hanging, too! The only reasonable solution to this is to move 23. Ba4 where the bishop threatens the black rook
I note that my comment above about 22......hxg4 23. bxc6 was already considered and discussed earlier by myevilluck and brigadecommander

correction
in my comment @ptitroque above, 23. hxh4 should be replaced by hxg4
|
|
My last comment.
Sorry, you're all right for 23. bxc6. I had a look on the wrong board image and didn't see the proper position.
|
|
White plays 23.Ba4, Black responds with 23...Rb7
|
|
What about
24. Bxc6 Bxc6
25. Ne5 ?

..meaning, of course, that he had captured the whole idea!

White plays 24.Bxc6 and Black moves 23....Bxc3

white plays 25,Ne5 and Black moves 25...Bb5
I showed before on a board diagram how the pawn structure looked with just pawns. If you notice,the squares c4,d6,b5 and ,c8,a8 are where Black is conducting operations. And they are all white squares. In one sense Whites c-pawn is backward and weak. As is blacks e6, but to a lesser extent (at the moment). Now black can, if he wishes at some point, play c4. But then Blacks a-pawn becomes significant,as does the b1-b8 corridor. (file). And the half open c-file is also important. My whole point is that the successful transition into an endgame will revolve around the White square complex and their adjacent files. These squares and corridors form a road net, By which one moves around on the Battlefield. This in turn is dictated by the pawn structure you have in any position. Now if my explanation seems a little vague, or imprecise, its because many of these ideas are swirling around in my head, and some i don't fully understand myself, other then on a subliminal level. Petrosian,Nimzowitch,and Smyslov were Giants in Positional Chess,and had there effect on me. But the one player who in my opinion had the simplest approach,and had an almost Mathematical 'Unifying Theory' was Capablanca. So every week i go over at least 5 of his games. And one last point. It was A.Alekhine that taught me to get 'every Piece i have out, on the board, and fighting,all working together in a pragmatic,'synchronized'' way.

the analysis
above by brigadecommander is excellent! I was expecting 25.....Bb5 and was already planning to move 26. Rf2. Sorry for the brevity, but I am abroad.
|
|
White moves 26.Rf2. Black,26...a4
also exhaustivel looked at were Qc7 and a4, also Bf6, and Qb6. I selected this move because it offers Blacks the best chances.
|
|
White moves 27.Ng6 and white plays 26....Rf6
White i think, plans to defend his backward c-pawn with his Bishop. So he may first exchange his Knight for the Bishop in order to gain a tempi by later playing Ba6, attacking whichever piece Black recaptures with. The resilience of the stonewall pawn formation can be seen here. The 'interlocking' pawns are very strong. Whether he can block the b-file and block the passed a-pawn remains to be seen. But his c-pawn is relatively safe now.

the trouble is
that brigadecommander reads my mind White needs to reduce blacks attacking power on the queenside. Taking black's DSB with the knight is much better that the bishop exchange after 27. Ba3. White needs his DSB!
