Re: White to Play and Win
The beauty of this study is seen if black was forced to play 4...Nf7+, then you will find white dancing with his bishop while black promoting to knights. There was a suggestion to put the black knight on h8 or e5 to get it, I have not checked.Dicaste wrote: ↑Sun Jul 03, 2022 2:39 amCode: Select all

Re: White to Play and Win
An old version of Crystal solves this one easily within seconds:
FEN: 8/3P3k/n2K3p/2p3n1/1b4N1/2p1p1P1/8/3B4 w - - 0 1
I also think in earlier posts in this forum that this puzzle was worked out to be a mate in 31 or something like that.

Re: White to Play and Win
The so-called Plaskett puzzle comes up again...
It's come up a lot here, and I think the most aggressive result from root was this from drewdrew's monster machine: forum3/viewtopic.php?f=2&t=68732&p=8309 ... tt#p831001.
One of the more amusing things about the puzzle is that the entry on Wikipedia has claimed for quite some time that there is no win after Kg4, citing a now-moved-or-absent very old Chessbase article, despite the fact that it's been known for quite some time that this is mate. A screenshot in this 2018 Chessbase article shows that someone had cloud analysis with SF showing mate in 30 starting at the second move (so consistent with drewdrew's mate in 31 from root).
Cheers!
