here is the extract from timkr.home.xs4all.nl:

"However, as Loyd himself mentioned, 24.Qe6 was not really played. Instead, he announced a mate in 6, beginning with 24.Nf5+. Only a quarter of a century later, did he "announce a mate more in accordance with the modern preference for problems in a few moves," with Qe6."

misterkool, based on the citation this is not a problem by Loyd, but one his games.

So Loyd found the mate in three after 25 years. That's why they started using chess clocks.

… Nxe6 2. Nf5+ Kg8 3. Ne7#
… 2. Nhg6+ Kg8 3. Ne7#

Some automated algorithm picks two puzzles each day, and puts the one with the highest solve rate on the left of the page, under the message header "Easy daily puzzle".

Why not Nf5 and # by R with K escape to g8 prevented by Q? Therefore mate in 1.

Sounds to me like the algorithm that selects the puzzles should be adjusted to pick two puzzles, each with a solve rate within a range of percentages. Then you could ensure the "easy" puzzle always has a solve rate > 40%, and a hard one always < 40%, (or some other percentage).

"The information posted by kingdawar is not entirely correct. The daily easy puzzle is picked from all puzzles rated 2 or 3 stars and the hard puzzle from all puzzles rated 4 or 5 stars, using a proprietary selection algorithm we have developed, so it is not entirely random. One a puzzle is picked and placed on the front page, its rating can change quite a bit, so the easy/hard puzzles are not guaranteed to stay 2-3 and 4-5 stars. The solve rate is shown, but is not used in determining whether the puzzle is easy or hard."

"The daily easy puzzle is picked from all puzzles rated 2 or 3 stars and the hard puzzle from all puzzles rated 4 or 5 stars"

I had totally forgotten about this!

the queen be taken with the rook with Rxe6?
