Mikhael Tal apparently solved this puzzle but Komodo11 and Stockfish 8 can't
work it out . Any programs out there that can find the mate?

I think the diagram has no photo because this position was already analyzed gazillion times?rabbits23 wrote:Mikhael Tal apparently solved this puzzle but Komodo11 and Stockfish 8 can't

But seriously it's because of your /W at the end of your fen notation I guess. Just compare above.

7. Be4 e1=N *
[/pgn]
Mate in 8 after e1=N but that is the beautiful main line, the stronger defence for black is different and would be longer than Mate in 16.
I think if a part of the fen "2p1p1P1" is used to searched the thread here at talkchess, there would be many hits for this position.

Re: Fascinating puzzle
My apologies, I tried searching using a part of the fen string, but the search function of talkchess doesn't function like the grep utility of the open source world. It doesn't return useful results, or maybe I need to learn some search tricks on this forum too.rabbits23 wrote:Thanks Mike. I'll work on sorting it out.

Re: Fascinating puzzle
Hi Mike!
Probably you didn't find the fen because there's one more pawn on h5 then in the orignal Van Breukelen- study, that has been discussed already here several times.
It just doesn't matter after 2.Nh5+ (Nxh5+)

Re: Fascinating puzzle
Thanks Peter ;you're right, there should not have been a black pawn on h5. It
was late at night and I was tired when I wrote up the position. I was unaware it had been exhaustively analysed either.
Cheers rabbits
