A test position.

Post by Farmor »

Position is:
[d]8/3k4/b1p5/P1P1P3/2PP4/2K5/8/8 b - - 0 99

This is what Rybka 2.2mp says at depth 33 with eval 0.03.
99. ... Ke6 100. Kb3 Kf5 101. Kb4 Bb7 102. Kc3 Bc8 103. d5 Kxe5 104. dxc6 Ba6 105. Kd3 Bc8 106. c7

I believe d5 is winning.
Do your engine see d5?

Rybka also thinks this when forced at depth 29 with eval 4.54

What do you mean? That after black plays Ke6, that d5 wins for white?
No it doesn't.

Or do you mean something else? That for example IF it is white to play in the position you gave, that d5 wins?
If it is so then yes is seems to win....

Sorry for the wrong position if Ke6 is played it's draw.
This is the position I mean that my rybka don't find the d5 if I don't force the move.
[d]8/1b1k4/2p5/P1P1P3/2PP4/2K5/8/8 w - - 0 2
But now I can't find the win anymore.
Very strange rybka gave +4 before but that was from a whole game I played on fics now it's only the fen.
I am a little confused over if I remember correct but I think so.
