Aug-14-17 | | zb2cr: 21. Ng6, threatening mate on both g7 and h8, looks unanswerable. First, maybe? |
|
Aug-14-17 | | zb2cr: First, definitely! |
|
Aug-14-17
 | | Phony Benoni: Not obvious. I naturally looked at 21.Qh8+ first, but it doesn't work with h7 not covered. |
|
Aug-14-17 | | Cheapo by the Dozen: Nxf7 is better than Ng6, since it obviates the defense ... f6, which slows things down quite a bit. White surely wins either way, of course. |
|
Aug-14-17 | | nalinw: Not so simple for a Monday because of the delaying defenses. Even for 21. Nxf7 there is
21. ... Bf6
22. Bxf6 Qxf7
23. Qh8# |
|
Aug-14-17 | | lost in space: Hello Cheapo,
I don’t think so.
21. Ng6 f6? 22. Qh8+ Kf7 23. Qh7#
21. Nxf7 and Black has nothing but desperate moves like 21..Qh2+ 22. Kxh2 Bd6+ 23. Nxd6 Rf6 24. Bxf6 Bh5 25. Qg7# What can Black do to avoid mate as long a spossibel in the first line with Ng6? 21. Ng6 Bf6 22. Ne7+ Qxe7 23. Rxg5+ Bxg5 24 Qh8# All in all 21. Ng6 is quicker.
I love Mondays |

White surely wins either way, of course.> Maybe I'm missing something, but it seems to me that if Black answers 21.Ng6 with 21...f6 there then follows 22.Qh8+ Kg7 23.Qh7#. |
|
Aug-14-17 | | ChessHigherCat: Ng6 threatening Qh8#. The black queen nobly tries to sacrifice herself with Qe5, but to no avail: Nxe7# In the variants 21. Ng6 f6/fxg6, 21. Qh8+ Kf7 22. Qh7# |
|
Aug-14-17 | | ChessHigherCat: <Infohunter> Make a wish! |

Aug-14-17 | | patzer2: For today's Monday (21. ?) my solution was 21. Nxf7 +- which mates-in-five. The game move 21. Ng6 +- mates-in-four per Stockfish 8. So I suppose it's slightly more efficient. Black's clearly decisive mistake was 14...Qc7? allowing the decisive demolition 15. Bxh7+ +- (+5.77 @ 35 depth, Stockfish 8.) Instead, the second player can put up maximum resistance in a difficult position with 14...Bxe6 15. fxe5 Qb6 16. Qe4 ± (+1.12 @ 28 depth, Stockfish 8.) Early in the opening, Black has had much more success in fighting fire with fire by countering 3. b3 with the more popular 3...b6 4. Bb2 Bb7 =
as in the recent drawn GM game S Golubov vs A Pridorozhni, 2017 or Black's win last year in C Aravindh vs D Anton Guijarro, 2016. |

Aug-14-17 | | jith1207: I got the solution without even realizing that the central theme of the puzzle is the e5 pawn defense. However, I could have gone wrong had I moved such as Nf3. |
|
Aug-14-17 | | agb2002: White has a bishop and a knight for the bishop pair. White can deliver mate with 21.Nxf7 Bf6 (else Qg7# or Qh8# or Kxh2) 22.Rxg5+ Kxf7 (22... Bxg5 23.Qg7#) 23.Qxf6#. Another option is 21.Rxg5+ Bxg5 22.Qxg5+ Kh7 (22... Kh8 23.Nxf7+ Kh7 24.Qg7#) 23.Nd7 and mate in two (23... Rg8 24.Qh5#). Also winning is 21.Ng6 f6 (21... Bf6 22.Bxf6 fxg6 23.Qh8+ Kf7 24.Qg7#) 22.Qh8+ Kf7 23.Qh7#. Other moves don't seem to be so fast. |
|
Aug-14-17 | | Cybe: Comfortably choice:
21. Ng6 – mate in 3
21. N:f7+ – mate in 4
21. R:g5+ – mate in 5
21. Nd7 – mate in 5
21. Nf3 – mate in 5
and maybe some others… |
|
Aug-14-17 | | paavoh: Unusually too many choices for a Monday puzzle. Took some time to decide on Ng6. |
|
Aug-14-17 | | drollere: i went for Rxg5+, Bxg5; Qxg5+, Kh8; Ng6+, g6; Qh6+, Kg8; Qg7#. more mayhem. |
|
Aug-14-17 | | saturn2: I took 21 Ng6. The answers f6, e5, Bf6, Qe5 and fxN only delay the inevitable. |
|
Aug-14-17 | | jith1207: I like Ng6 Qe5 and Nxe7# |
|
Aug-14-17 | | saturn2: The game is a nightmare for a sicilian player. |
|
Aug-14-17 | | diagonalley: hard for a monday... |
|
Aug-14-17 | | Monocle: Looks like there's more than one solution.
I went with 1.Rxg5+ Bxg5 2.Qxg5+ Kh7 3.Nd7, with mate after a few delaying moves. This seems to work. Saccing the rook on g5 looked like the most 'monday' solution, and I never even looked at Ng6, although it appears to be quicker. Unusually complex for a monday. |
|
Aug-14-17 | | Cheapo by the Dozen: I sit corrected.
Thanks, <lost in space>. |
|
Aug-14-17 | | malt: Gone for 21.N:f7 Bf6 22.Qg6+ |
|
Aug-14-17 | | morfishine: <21.Rxg5+>
***** |
|
Aug-14-17 | | JohnBoy: If 18...g6 does white have anything better than 19.Qe2? |
|
Aug-14-17 | | JohnBoy: Yeah...
18...g6 19.Nxg6 Bxb2 20.Ne7+ cruises home. |
