 | | 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… |

 | | 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. |

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. |

 | | takchess: Notes after looking at the answer.For move 21. I looked at Qh8, Nf7 and finally decided on Rg5 +. This Monday does not bode well for the rest of the week. Didn't even investigate the correct solution |

 | | patzer2: <takchess> As long as you saw the win after 21. Rxg5+ +-, give yourself credit for the Monday solution. Masters in their games quite often find wins that are not the quickest or technically best. A win is still a win, regarless. Unless it's a puzzle solving competition (i.e. find mate-in- four etc.,) it doesn't matter. |
|
Aug-14-17 | | Crowaholic: Ng6 is not mate in three because of the ..Qxh2+ zwischenzug. |
|
Aug-14-17 | | DrGridlock: Rather nuanced for a Monday puzzle.
Both Rxg5 and Ng6 lead to mate (though Ng6 is the quickest mate). I went for the Rxg5 line, but this leads to mate only after 23 Nd7. The branch I analyzed instead was 23 Ng4. This does NOT lead to mate, because black can throw a blockade on the a1-h8 diagonal with f6 and e5 (I missed this), but this line DOES lead to overwhelming material gain for white (a queen and four pawns for the exchange). |

 | | kevin86: A subtle key move by white- as subtle as a chainsaw. |
|
Aug-14-17 | | DarthStapler: Doesn't Nxf7 also work? |
|
Aug-14-17 | | Tiggler: According to Houdini, White has 49 legal moves and at least 16 of them are mate in 7 or less. |

Or mate in four after 23... Qxh2+ 24.Kxh2 f6. I noticed this just after closing CG's page and was about to rush to the office. That's why I often prefer "and mate soon" instead :-) |

 | | gawain: I chose 21 Ng6 which seemed most forcing and efficient and prettiest, too. |
