| Apr-07-22 | | Brenin: I soon saw 30 ... Qxf5 31 exf5 Rxe1+ 32 Kh2, and originally intended 32 ... Kg7 with the intention of 33 ... Rh8+, e.g. 33 Qxf4 Rh8+ 34 Kg3 Nh5+ winning the Q. However, I then realised that the game line 32 ... g3+ was even stronger, with a royal N fork on e4 instead. |

White threatens Qxf4.
The black rooks x-ray the white rook on e1. This suggests 30... Qxf5 31.exf5 (else drop a piece) 31... Rxe1+: A) 32.Kh2 g3+ 33.fxg3 (33.Kh3 Rh1#) 33... fxg3+ 34.Kh3 (34.Kxg3 Ne4+ and 35... Nxd2 wins decisive material) 34... Rh1+ 35.Kxg3 Ne4+ wins decisive material. B) 32.Qxe1 Rxe1+ 33.Kh2 g3+ 34.fxg3 fxg3+ 35.Kh3 Rh1+ 36.Kxg3 Ne4+ and 37... Nxd6 wins decisive material. |

Using Stockfish 14 because it solves for mate better than 14.1 : When White resigns it's mate in 17:

| Apr-07-22 | | TheaN: More on the easy side than medium, given there's not much to consider from Black's end. Really just <30....Qxf5> makes sense from a combination point of view. It wins, given Black wins at least a piece on penalty of <31.exf5 Rxe1+ 32.Kh2 (Qxe1 Rxe1+ -+) g3+ 33.fxg3+ fxg3+ 34.Kh3 (Kxg3 Ne4+ -+) Rh1+ 35.Kxg3 Ne4+ -+> and the fork Black was looking for happens, and Black goes rook and piece up. |

| Apr-07-22 | | Cellist: I chose the original line that <brenin> selected (with 32. ... Kg7). Not nearly as good as the game line, but it also wins. |
|
| Apr-07-22 | | Brenin: Despite a certain amount of faffing about (taking four moves to exchange his LSB for Black's undeveloped LSB, and the show-jumping display from moves 20-23), White had a reasonable position until 30 Qd2 made his Q forkable by Black's N. Instead, 30 Re2 would have defused Black's Q sac by allowing 30 ... Qxf5 31 exf5 Rxe2 to be answered with 32 Qd4, winning the N. Even so, White has to tread carefully, e.g. 32 ... Re1+ 33 Kh2 g3+ 34 fxg3 (not 34 Kh3 Rh1 mate) fxg3+ 35 Kxg3 and now Black is running out of counterplay. |

| Apr-07-22 | | AlicesKnight: Found the gameline. A fascinating perception. Something about the shape reminded me of Euwe vs Lasker, 1934 - though I'm not sure why (perhaps the R+N for Q element, or the central file dominance). |

| Apr-07-22 | | raymondhow: For some reason I had blinders on for 30 ... Qxf5. Had I considered it, likely I would have chosen it. Instead just kept staring at 30...Nxe4 which doesn't work. |
