| Jan-02-21 | | stacase: I got the first two obvious moves of an eleven move series. Puzzle should have probably started at 30...Kf8 White to move. |

 | | al wazir: After the obvious 29. Rxg7 Kxg7 30. Rc7+ Kf8, I would have played 31. Nf6. It *almost* works. If 31...Qf4, then 32. Nxh7+ Kg8 33. Qxg6+ Kh8 34. Qg7#. If 31...Qg3 , then 32. Nxh7+ Kg8 33. Qd5+ Kh8 34. Qf7 Rg8 35. Qf6+ Rg7 36. Qxg7#. If 31...Qh6, then 32. Nxh7+ Kg8 33. d5+ Kh8 34. Qxe5+ Kg8 35. Qe6+ Kh8 36. Qf6+ Kg8 37. Qf7+ Kh8 38. Nf6, with 39. Qh7+ and 40. Rxh7# to follow. But I don't see any way to win after 31...Rd6. |

White must still be better/very close to winning thanks to weak black king/the Rook on the seventh. Game continuation is of course superior. |

 | | An Englishman: Good Evening: Not giving myself credit for this one due to choosing the second-rate move 31.Nf6. Still, did solve Saturday, and 5/6 for the week with one known rates as better than usual for me. |
|
| Jan-02-21 | | Walter Glattke: White can play 29.Rxg7 Kxg7 30.Rc7+ Kh8 31.Nf6 Rd2!? 32.Rxh7+ Qxh7 33.Nxh7 Kxh7 34.Qxe5 Rbd8 35.Qxa5 with white advantage, hard to win |
|
| Jan-02-21 | | Brenin: The first two moves were obvious, but the follow-up wasn't. I would have played 29 R1c2 and/or f4 first, before Rxg7. |
|
| Jan-02-21 | | goodevans: Not a fan of puzzles with more than one right answer. I went with <29.f4>. Black's B isn't going anywhere so no rush to take it and if black tries to defend it with 29...Rg8 then 30.Rh1 wins the Q (30...Qg3? 31.Rxh7+!). As several have already hinted at, the game continuation gets quite hard to find after the first couple of moves. After 29.f4 it's so much simpler. |

 | | pawn to QB4: I went 29.Rg7 Kxg7 30. Rc7+ and if Kf8 then 31.f4. Glad to see Stockfish is OK with that, but I was hoping 31. Qc4 also works. I like the non-checking move, and there are multiple threats, e.g. 31...Re8 32. Nf6 Re7 33. Qg8 #, or 31...Rd6 32. Nb6 Rf6 33. Nd7+ and Nxb8. Is there a better defence for Black after 31. Qc4? |

 | | agb2002: White has a knight for a bishop and a pawn.
Black has Rxd5 if necessary.
White has Rxg7 and f4 to weaken e5, Black's strong point. In the case of 29.f4:
A) 29... exf4 30.Rxg7
A.1) 30... Kxg7 31.Rc7+ Kh6 (else mate in two) 32.Nf6, with the double threat Rxh7+ and Ng4+, is winning. A.2) 30... Rxd5 31.Qxd5 Kxg7 (due to Qe5 or Qd4) 32.Qe5+ and 33.Qxb8 wins decisive material. B) 29... Rxd5 30.Qxd5
B.1) 30... exf4 31.Rxg7 transposes to A.2.
B.2) 30... Qxf4 31.Rc8+ Rxc8 32.Rxc8+ Bf8 33.Qxa5 followed by a simultaneous attack against Black's whole position, in particular the b-pawn. -----
I'd play 29.f4 since it looks easier than a direct Rxg7. |

 | | drollere: as others note, the B on g7 is a mating threat if e5 is advanced (Qxb2#), so Rxg7 Kxg7, Rc7+ seemed necessary to release the Q from its blocking role. i rejected Nf6 due to Rd2 which seemed very bad, but did not see a way forward either. it was very instructive to see how white manipulates black's position through the series of nine Q and R threats supported by a very nimble N. |
