Study: white to play and win

Post by acase »

This is a study by a current world class study composer, don't try to search for the FEN, you probably won't find it, besides I'll reveal the source, year, and event complete with a PGN later on as some people like to try and solve these themselves.

I think there is a forced mate here in no more than 44 moves and it might be even shorter than that. Enjoy :D

Re: Study: white to play and win

Post by Eelco de Groot »

7...b3 is not the best move it seems Chessqueen? That's why you get a shorter Mate I think.

Rebel quickly settles on the variant from Paloma, but it does not have tablebases at least I don't think it can do that?

So it does not know the distances, but plays the right moves, only I am not sure how long Black fights if 2...Kd7

Rebel fails high here, but no new output for half an hour

Without tablebases, this would be the analysis from Rebel, helped with Shredder GUI that does have tablebase access:
