No weak square !

Post by HangingKing on November 3rd 2009, 3:31 am

While practicing tacticals with ct-art, i found this very interesting position, fitting very well in the ICS pawn lessons.

It is white's turn, and one may think that the position is hopeless since the bishop will have difficulties to hold the position on the queenside against the rook, even if white has some pawns up.



In fact, white can improve his position by eliminating all the weak squares.
This is done by :
Kd1, Rh2
Ke1, Rxg2
Kf1, Rh2
Kg1, Rh3
Kg2 ... chasing the rook which happily ate the bishop.

Then move pawn f2-f3 closing the position.

Eventually after a-pawn move this lead to diagram below :



You can notice that the bishop sacrifice is not an issue, since there is no way for black to enter the position. All sqaures in front of the pawns are guarded, and the d2 pawn guard the critical entrance square e3.
Whatever black do white only has to move his king on the f1,f2,g1,g2 squares and it is a fine draw.
(eventually move a4 or b4 if black try to break through).

I'm very impressed by this position illustrating the power of pawn structure.

Would you have figured out this solution ?


I tried to with chess engines, they all are unable to see the drawish nature of the position...

It's funny I knew the solution instantly, but there is no way I would have worked it out. I have never used ct-art but clearly I have seen this position somewhere before as soon as I saw it I knew that Ke1 followed by Kf1 was the way to go.

Weird, now I'm going to have to remember where I saw this. Gut feeling is telling me Yasser Seirwan so maybe its in one of his Winning Chess books. I will have to dig them out and have a look.

Good to know I've subconsciously absorbed something though!
