test position is it correct?

Post by Uri Blass »

[D]8/1p6/p7/3b4/4kPp1/P5Bp/1P2K3/8 w - - 0 52

This is from one of a tournament game that I played few days ago.

I believe that my opponent found the only drawing move
52.f5
It seems that line like
52...Kxf5 53.Kf2 Ke4 54.Kg1 Kd3 55.Kh2 Kc2 56.Be5 is a draw

I believed that I can win by 52...Bc4+ but
after 53.Kf2 Kd3 54.Kg1 Kc2 55.Be5 I found that my plan does not work because after 55...g3 56.Bxg3 Kxb2 Bd6 I cannot protect h3 and prevent the f pawn to queen and I cannot win 2 vs 1 pawn endgame
I tried to go back by Kd3 Kh2 Ke4 Bc3 Kxf5 and unfortunately I had no win(I posted the final position of the game in another thread).

It is possible that I missed something in the analysis so I ask you if I am right and if there is a chess program that can find f5

It seems that I can beat easily chess programs here with black and draw with white.

Uri, isn´t 52. Kf2 a draw? Maybe f5 could be move later.

I think that 52. Bh2 is a draw too.

{all others lose very quickly.}
I think all diagrams that have pawns in b2 and a3 are draw.
And the epd 8/1p6/p7/3b4/4kPp1/P5Bp/1P2K3/8 w - - bm f5; c0 "Kf2 or Bh2 seems rigth to me. In short, from the first position post by Uri,
f5, Kf2 and Bh2 are draw.
But I liked that Uri or others CCC members saw if I am rigth.

It seems that you are right
Black has one more tempo but it does not help him in these lines

Maybe better test position is after Kf2 Kd3 when you need to find f5

[D]8/1p6/p7/3b4/5Pp1/P2k2Bp/1P3K2/8 w - - 0 53

Toga solves it but does not see the idea of Kc2 against other moves:

Alternatively you can have test position after 53.a4 or 53.Bh2 when you need to find Kc2 for black.
