 I think |

I suppose, sh'll elect the Queen because, anyway, ther's no better place for the rook than the actal one, but she could have seen something I miss

White plays 28.Nxe7 Black,28....Qxe7 29.Ba3...Qc7

passed pawn
Looks like white otta' double up them castles and deal with that black pawn. There is no way to go around it. you have to steamroll over it ! be subtle about it.

Transitioning to the Endgame.
Whites DSB cannot attack the black pawn because its on a white square. Conversely Blacks LSB cannot attack whites weak c-pawn for the same reason. Without the assistance of a Minor Piece neither side can capture each others central pawns using Rooks,as that would lose a Rook for a Bishop. The idea of some sort of exchange sacrifice could happen, but it is highly dubious for either side. Blacks strategy is to 'infiltrate' the enemy lines by using the 'white square complex'. Whites strategy 'may' involve defending his position using the 'black square complex'.

The black "passed pawn"
is indeed well protected by the black LSB and cannot be taken on that square with anything else than a rook (or a queen). since white's bishop functions on the dark squares. White now moves his bishop to protect the weak c3 pawn. At the same time the white DSB at b4 blocks the b file (for the black rooks) and is being protected himself by the c-pawn. Nice collaboration!

White plays 30.Bb4 and Black plays 30.....Qc4
|
|
30. Qc4
The queen cannot be attacked by anything else but the opposite queen and even in that case, she's protected by the WSB. In a center position, she's very dangerous but cannot easily move to the left wing to defend in case of necessity.

the e3 pawn is in danger
after blacks Qd3, but white counters by an advance on the h line because he does not want black to occupy h4
|
|
did you consider
31.Rb2. in which case the white Queen can defend the e-pawn.
|
|
The Invasion Begins.
White plays 31.h4. Black moves 31....Qd3.... I believe (i may be proved wrong) that Whites 31.h4,to be a slight miscalculation. It was essential that white play 31.Rb2 so as to 1.Deploy the Rook.2. And more important, allow for the defense of his e-pawn by his Queen.
|

Counting the moves
If I understand well, we are in a situation where both players lead an attack on two diret points and the whole problem is to evaluate how many moves one can afford to attack before being obliged to defend against the opponent attack. (I'm not sure to be very clear when explaining it in english).

@ptitroque
I think your point is crystal clear! This is one of the key problems in chess. Can you achieve your goal in a sufficiently small number of moves, relative to the number of moves your opponent needs to crush you ?

@brigadecommander
Just back from my business trip, I realise that I may not have given the previous few moves sufficient thought (made at a hotel with very poor internet contact). Hmmm, but I am not sure that 31. Rb2 had been much better than 31.h4, because aft6er 31. Rb2 black could have escalated a good kingside offensive by 31....g5. However, brigadecommander's note on the defense of white's e-pawn is important..... I may have been mistaken?

To me it just looks like a draw. 31. h4 is probably as good as any. The point is it is pretty hard to mess this position up.

the concern about white's e-pawn
is perhaps, after all, not that serious? White simply moves 32. Re1. At this stage, my impression of the game is that black is slightly ahead, but that white might be able to get a draw at best.
It would be great to get an independent evaluation from our able Masters klauno, elyhim and myevillook

The way I look at the board blacks plan is wrong. I think it needs to do something gutsy to try and win, but it might be a bad idea. The e-pawn is not the weakest point. The bishop is, but like a I said. It'd be gutsy, and needs to be setup properly.

White plays 32.Re1 and Black plays 32...Rg6

rearranging.....
brigadecommander plays really strongly here & in this respect I respectfully disagree with myevilluck. I want to mobilise my queen and put my king on h2, but I think I will need something more than luck, or evil luck , to get a draw out of this position

White Plays 33.Qg2 and Black moves 33...Be8
|
|
33. Qg2 a3
There's probably something I oversee but what if
33.Qg2 a3
If 34. Bxa3 Qxg4 (fork attack)
Else : 34. ... Ra7
and/or 35. ... Qc4 to protect the passed a pawn ?

@ptitroque
Sorry, whilst I understand 33.Qg2 a3, and 34. Bxa3, I don't understand 34....Qxg4 (fork attack). Please, explain
|
|
@stalhandske
Sorry, Qc3 (the g4 square has nothing to do with it)

I would say, but it would give a lot of key moves away. All I can say is 34. Bxa3??? is a huge blunder.
|
|
@myevilluck
I agree, that's why 33. ... a3 would have been good for black (there must be something I missed)

Having the pawn on a dark square would be a liability long term. Short term he can't take it, but that doesn't mean down the line it isn't possible.

Endgames are a different beast in chess. You need to nourish your advantages and keep them as such. Blacks goal isn't to get the pawn to a3. The goal is to get it to a1, so a path needs to be paved for it. This is why I don't understand 33. ...Be8. That bishop had a great square it could get to.

it is suggested that after 33. Qg2
black would do well in playing 33.....a3. Incidentally, after that 34. Bxa3 is indeed a complete blunder losing the game, because of 34......Qxc3 by which white loses the bishop.
As a matter of fact, I think 33.....a3 is not a very good move. After 34. Kh2 or 34. Ra2 I think the balance has shifted from having been somewhat in black's favour into a discrete favour for white.
In this respect, I think brigadecommander's 33....Be8 is better

@myevilluck
yes.....and that square is c4 which is where I had expected black to move instead of 33....Be8
|

nevertheless....
my analysis of the situation after 33.....Bc4 suggests that white can hold the fort for a draw
