 | | patzer2: I went with 31. R1xd7 (mate-in-12, Stockfish 9), but as <Walter Glattke> observes 31. R8xd7 +- (+26.88 @ 30 ply, Stockfish 9) also wins. |

 | | thegoodanarchist: I failed to solve the puzzle.
I found 31.R1xd7, followed by 32.Qxf7+.
But instead of 33.Qg7#, I played the "greedy" 33.Qxh7# |
|
| Aug-28-18 | | Mayankk: Not really a puzzle, is it? Just the standard capture and mate later in a simple sequence. Even ‘easy’ puzzles should have a puzzling element to them. For example a few candidate moves which seem tempting or a sacrifice which is not too obvious. |

 | | perfidious: Why on earth is this posted as a puzzle? A novice could 'solve' this without difficulty. |

 | | Once: Folks, I think this is CG getting back to "normal". For the first time since we lost Daniel, we've got a wholly new POTD and not one recycled from a couple of months ago. So sure the puzzle is a little iffy but I think we should cut Sargon a bit of slack as he gets the site back on its feet. |

 | | OrangeTulip: Complaining as second nature, one has to deal with that. Obviously it is a puzzle. (Okay 1,5 stars only) With which rook to take? |
|
| Aug-29-18 | | swclark25: I saw R1xd7, but what if Black went with 31...Qxd7 then 32.Rxd7 Rf8. What would White do for move 33? |
|
| May-10-21 | | Nullifidian: 31. ♖1xd7 wins the bishop outright and the queen will have to be given up if black wants to continue the game, because ♖f8 can't defend if the rook is pinned along the eighth rank. After 31... ♕xd7 32. ♖xd7 ♖f8, 33. ♗e4 threatening the sacrificial 34. ♗xg6! is an interesting continuation. Black will be forced to capture with 34... ♙hxg6 and after 35. ♖d4 nothing black can do will stop ♖h4 and ♖h8#. |

 | | drollere: 21. R1xd7, and .. Rf8 or Rxd8 fail to 22. Qxf7+ and mate next. 31. .. Qxd7, 32. Rxd7 Rf8, 33. Bxb7 Rab8, 34. b5 wins Q for R and white has two linked passed Qside pawns. |

| May-10-21 | | Brenin: The Black B on d7 is en prise, and the only puzzle here is which White R should capture it. Clearly 31 R1xd7 is strongest, nullifying the defence 31 ... Rf8 against 32 Qxf7+ and 33 Qg7 mate, and thus forcing Black to concede more material. |
|
| May-10-21 | | Brenin: Black's goose was cooked with 25 ... Re8, after Which white needed only to make natural attacking moves to develop an overwhelming position (for example, c6 will cause Black's position to collapse). Instead, 25 ... Rd8 and 26 ... Ng6 would have kept Black alive, though only just. |
|
| May-10-21 | | TheaN: <31.R1xd7 +-> however, I missed the simple 31....Rf8 32.Qxf7+! with mate in one. After 31....Rf8 I intended 32.Rxa8, but after 32....Qxd7 White 'just' wins the piece. It's dead won, but not as fast. |
|
| May-10-21 | | AlicesKnight: R1xd7 followed by puzzling over what I might have missed..... |

 | | Messiah: Black's entire set of ideas is deeply questionable in this game. |

| May-10-21 | | goodevans: <Aug-28-18 Once: Folks, I think this is CG getting back to "normal" [...] a wholly new POTD and not one recycled from a couple of months ago.> Unfortunately the <new "normal"> seems to be frequent recycling of puzzles. At least today, unlike yesterday, they got the day right although quite why someone would think this lame offering was worth a second outing beats me. I've no idea by what mechanism the daily puzzles are chosen. I know other kibitzers have offered to help in the past to try to re-establish their quality and I'd be happy to throw my hat into the ring in that respect. |
