Kibitzer's Corner
Oct-16-24  TheaN: An incredibly odd combination, that I honestly have never seen before. White would like to fire on Black's weak back rank with <27.Rd1>, slight issue is that after <27....Qxe2> the rook's in and 28.Rxd8+? Be8 (Rxd8? 29.Qxd8+ Be8 30.Qxe8#) 29.h3 Rxd8 30.Qxd8 Qxb5 -+ <loses> for White.

So instead we have to find the counterintuitive <28.Nc3! +-> to defend Rd1: now Black has no way to protect d8 as well as saving the queen, so 28....Qxd1 29.Nxd1 +- is best. There are no reasonable alternatives to consider for Black on move 27 as the bishop's defending the rook so White can just fire Rxd8+ otherwise.

Oct-16-24  TheaN: Oh, would you know, I missed 27....Qg5!: Black simply defends Nd8 and now White's job to increase pressure. Yes, 28.Nd6 +- but didn't consider it at all. Alas, if 27.Rd1 is fine because of the aforementioned combination White's improving the position so I'll take it as a solve.

27. Rd1

(27. Rd1 (1.Rd1 Qg5 2.Nc7 Ra2 3.Qd4 Nb7 4.Qc4 Qe3+ 5.Kf1 Rb2 6.Nxe6 h5 7.Nd4 Ba4 8.Nf5 Qg5 9.Rd5 Kh7 10.Qd4 Rc2 11.Qe3 Qxe3 12.Nxe3 Rb2 13.Ba6 Rxb4 14.Bxb7 Rxb7 ) +4.13/47 476)

score for White +4.13 depth 47.

Oct-16-24  King.Arthur.Brazil: The king saw the line: 27. Rd1! Qxe2 28. Rxd8+? Rxd8 29. Qxd8+ Be8 30. Qxe8. What can B reply 27...? For 27... Qg5 28. f4 Qe7 29. Rxd8+ Rxd8 30. Qxc6... with some advantage.

However, I failed because B is not forced to capture, instead 28... Be8 wins for B, cause if Rxa8?? Qd1#. The correct is 28. Nc3! Qc4 29. Rxd8+ Be8 30. Rxa8 or 28... Qa6 29. Rd8+ Be8 30. Rxe8+ Rxe8 31. Qxa6 (win the ♕).

  scormus: Don't I can honestlyclaim to have solved this. I was pretty sure about 27 Rd1, and was expecting .... Qg5, defending the Rd8. Reason, I thought at the time W should be winning after 27 ... Qxe2 Qxd8+. Only then I realised W wasn't winning.

<Thean> Oh, would you know, I missed 28....Nc3!

  Dionysius1: That made my evening. I didn't come close to solving it. So much for pattern recognition as an aid - the solution doesn't conform to any pattern I remember seeing. How fresh - exhilarating!

In text it's a bit hard to read a jab but considering you copied the phrasing I think you are... fair because it was a bit cheeky to post it like that: came more from an astonished point of view rather than being like "normally I don't miss it", because I miss enough moves... one of the reasons I keep doing these puzzles.

It's a subtle position: the retreat to c3 or g5 are easy to overlook, and I'd argue you actually need to spot both to claim a solve, but the former's more important as it justifies Rd1 Qxe2. After Qg5 the game continues with a large White advantage.
