Is this study "cooked"?

Post by acase »

Here is a problem I was looking at from The Problemist 2020-2021, it is a white to play and draw but it looks like Crystal 5 KWK thinks that 2...Bb8 wins for black. I should also mention that I am NOT using tablerbases.

{4. Bb5! is great, but the lines after the alternatives, for instance 4.
Kf5 are incomphrehensible to me. Also, I feel that the sacrifice ought to
be used in a win study somehow.} 1. c4 {$1 to stop the pawn since after}

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Hi Eelco,

It looks like after 12...Kc6 in that position that the white king has nowhere to move and if black can get the knight to either the c7, c5, b4, or b8 squares then white is mated, the problem is it looks like the white bishop can kick the king off of that c6 square before the knight gets to one of the mating squares.

disregard that last post I made, clearly after 12...Kc6 white can move his king to a7 still, it's too early in the morning here for me :D

Hi Andrew i'm not very good at endgames, but the score seems convincingly big? Well anyway, I'm glad this new Rebel can give Mate, with Bishop and Knight now. It's a huge improvement over 15.2!. So rebel new age Mates at move 105! It is just auto play at 1 minute per game so not very high quality analysis... Autolog from Shredder (previous Rebel Beta could not do this, thanks to Chris and Ed :) )
