May-09-21  Pawn Slayer: al wazir: This can't be the right puzzle.
In the game line white gets ♕+♗+♙ for a ♖. The only (slightly) interesting alternative is 23...Kf7 24. Rxh5 Bxb3 25. Rxh6, winning ♖+♙.

23 Kf7 doesn't work at all. White doesn't take on h5, but simply moves his Queen and the black Queen is trapped.

May-09-21  johnnydeep: Insane?! I think not. The first two plies were screamingly obvious even for me!

<May-09-21 mel gibson: <Apr-11-21 mel gibson: I wondered why I solved it in under 1 second. I have already solved it with Stockfish 3 times.>

So easy it's Monday easy -
and the 4th time I've solved it.>

I've solved it 5 times now.

Premium Chessgames Member
  FSR: I like 23.Rxg5+ Qxg5 24.Qxe6+ followed by 25.Nxg5. Or 23...Kf7 24.Rxh5 Bxb3 25.Rxh6.
Premium Chessgames Member
  perfidious: It is a far from simple matter for a POTD to metamorphose from a Sunday-level solution into Monday-type stuff, but this one has managed to pull off that feat.
May-31-21  Cheapo by the Dozen: Adding to the confusion, today in the US is a holiday Monday that feels like a Sunday.
May-31-21  saturn2: 23 ...Qxg5 or King moves lose a piece
May-31-21  Walter Glattke: Third time this puzzle.
May-31-21  malt: As Walter says.
May-31-21  stacase: Second verse, same as the first,
A little bit louder, a little bit worse!

Except that this is the third time around.

<mel gibson. . . I've solved it 5 times now.>

Third, Fifth, Monday, Sunday; doesn't much matter.

  drollere: at least seems to have settled on a single puzzle as the POTD stopgap.

i actually puzzled for several moments over how to kill N at f3, thinking it was black to move.

black must have had similar thoughts before the ceiling came down.

Premium Chessgames Member
  halito27: For once, I agree with <chrisowen>.
Sep-20-21  Cheapo by the Dozen: I didn't remember this from last time. Hard Monday or easy Tuesday for me, in that a solution required seeing all of:

-- Material starts out pretty even.

-- 23 Rxg5+ breaks the pin with check.

-- The game line saves White's queen while still leaving time to take Black's.

-- If Black instead steps out of check on Move 23, White's rook is protected, so White can just play 24 Qxe6.

-- There are no lines in which White actually plays RxQ.

  Phony Benoni: Already used twice this year on Monday, April 5 and Sunday, May 9.
Sep-20-21  Brenin: At the risk of becoming boring, the obvious 23 Rxg5+ wins material, e.g. 23 ... Kf7 24 Rxh5 Bxb3 25 Rxh6, or 23 ... Qxg5 24 Qxe6+ and 25 Nxg5 (as many, including myself, have stated earlier this year).
Sep-20-21  stacase: I think I solve it a little faster each time it comes up.
Premium Chessgames Member
  FSR: <May-31-21 FSR: I like 23.Rxg5+ Qxg5 24.Qxe6+ followed by 25.Nxg5. Or 23...Kf7 24.Rxh5 Bxb3 25.Rxh6.>

I emphatically agree.

Premium Chessgames Member
  FSR: This is just as easy as it was the first five times. I refer you to <FSR>'s prior comments.
Sep-27-21  Brenin: Oh, no, not again? 23 Rxg5+. No more to be said this tlme.
Sep-27-21  Cheapo by the Dozen: On the other hand, my previous comments don't wholly apply today, because this time around I DO remember the puzzle from before.
Premium Chessgames Member
  Phony Benoni: The is just the POTD version of Timman and Karpov and the Non-Safety Pun. It was changed last Monday, and hopefully will be changed again today.
