| Sep-23-17 | | goodevans: <Boerboel Guy> 42...e3 and I'm not sure whether white has a win. <BxChess> "41...Qd7 (what else?" - How about YouRang's 41...Na4? |
|
| Sep-23-17 | | WorstPlayerEver: 34. Rd6 cd6 35. Qd5 Kf8 36. Bf4
2 minutes, not bad for a Saturday puzzle :) |
|
| Sep-23-17 | | WorstPlayerEver: <patzer2: I was stumped and went for the flawed "win of a piece" in attempting to solve today's Saturday (34. ?) puzzle with 34. Rxe4?> Yeah, first I had the same feeling eying at c5, but then I noticed White was a piece up ALREADY. Black seems to have sacked one. Thereafter the solution came almost instantly to me. For the first rule is: look at all the pieces! |

 | | patzer2: <WorstPlayerEver> Thanks! Since White starts a piece up, I guess my flawed "win of a piece line" was actually a flawed simplification to keep the "extra piece" at too high a price (i.e. the four pawns Black gets for the Bishop after 34. Rxe4?) |

To my surprize Stockfish plays the same line. I looked at Bh6 or Rg7 -as sole moves- for a split second, but didn't see the combination. However, I spend only 1 a 2 minutes on a puzzle. Depends on the day. Since we are speaking of game continuations, I try to simulate time pressure that way. I can recommend this method; I rarely run into long -wrong- analysis these days :) After all, like Kramnik has stated before; it's all about building confidence. Lack of confidence is the greatest enemy of every chess player, I assume. |

| Sep-10-21 | | catlover: Too difficult for me. Maybe I'll remember the solution to this puzzle next time around. |
|
| Sep-10-21 | | Brenin: 36 Rxd6 cxd6 (can Black survive with 36 ... Rd5, to stop 35 Qd5+?) 37 Qd5+ Kf8 (37 ... Ke7 38 Rxg7+) 38 Qxd6+ Kf7 (38 ... Kg8 39 Bxh6, or 38 ... Re7 39 Rxg7) 39 Bxh6 gxh6 40 Qd5+ seems be winning. |

 | | Breunor: Maybe this is harder than 3 stars? |
|
| Sep-10-21 | | rbhgroup: I found 34. Rxd6 to be followed by 35. Qd5+ fairly quickly, but could not see anything definitive for White after 34...Re5. After that, it was just a wild goose chase looking for a better idea... |

| Sep-10-21 | | mel gibson: I saw that move but I wasn't sure -
it's so complicated.
Stockfish 14 agrees with the first ply:

score for White + 7.57 depth 38 -
but Black doesn't take the Rook.
However -
if Black does take the Rook -

| Sep-10-21 | | padraic: Pronounced "Yeshur," the sh voiced. So yeah sure, sure. A wonderful attack, too deep for me. |

 | | drollere: wow, sacrifice a R just to get it out of the way. "get off that square, i need it!" i saw W was up a piece, so a sacrifice was worth it; i recognized that the Q had almost no useful moves, except perhaps for a1. but didn't see that solution. |
|
Sep-10-21
| | drollere: that pawn on f5 turns out to be worth 2 Rs. |
|
Sep-10-21
 | | raymondhow: I got the first two moves, then wanted to play 36 Qxd6+. So that's probably a no-solve, durn it. |
|
Sep-10-21
 | | Teyss: Splendid despite some imperfections. Summary of above posts for lazy weekenders:
- Black shouldn't have taken the first R although 34...Re5 also loses;
- 36.Rxg7 is very impressive but only brings a small advantage whilst 36.Bxh6 or Bf4 wins;
- 38...Rg8 would have been better than ...Qd7? leading to a forced mate but would also have lost.I especially like the variation 37...Kxh6? 38.Qf7. Black is 2 Rs up but can only avoid mate at huge cost.

| Sep-10-21 | | awfulhangover: 36.Qxd6 + my choice, and also seems to win. |
|
| Sep-10-21 | | Cellist: I saw the first two moves but then went for the obvious 36.Qxd6+, which also wins, albeit less elegantly than the triple sacrifice. |

 | | Honza Cervenka: If 38...Rg8, then 39.Qxf6+ Kh7 40.Qh4 Rc8 41.Bf4+ Kg8 42.Qg5+ Kh8 43.Qh6+ Kg8 44.Qg6+ Kh8 45.Bxd6 Nd7 46.f6 Nxf6 47.Qxf6+ Kg8 48.Be5 Qd7 49.Qg6+ Kf8 50.Bd6+ looks like a forced win for white. |

| Sep-10-21 | | johnnydeep: The first rook sac was puzzle-obvious, but the second rook sac was definitely not! |

 | | Jimfromprovidence: <Honza Cerevenka> <If 38...Rg8, then 39.Qxf6+ Kh7 40.Qh4> I missed 40 Qh4, below, in this line. I thought the position was a perpetual after 38...Rg8.
click for larger viewIt's difficult to fathom that despite being down two rooks vs a bishop and a pawn that after 40 Qh4 white is in the drivers seat. |

 | | agb2002: White has the bishop pair for a knight and three pawns. White would like to play Qd5+. This suggests 34.Rxd6: A) 34... cxd6 35.Qd5+
A.1) 35... Kf8 36.Rxg7 Kxg7 (36... Ne6 37.Qxb5 wins) 37.Bxh6+ A.1.a) 37... Kxh6 38.Qf7 Rg8 39.Qxg8 Qe8 40.Qxe8 wins. A.1.b) 37... Kh7 38.Qf7+ and mate next.
A.1.c) 37... Kh8 38.Qf7 Rg8 (38... Qd7 39.Bg7+ Kh7 40.Qg6+ Kg8 41.Bf6+ Kf8 42.Qh6+ and mate in two) 39.Qxf6+ Kh7 40.Qf7+ Kh8 (40... Kxh6 41.Qxg8 as in A.1.a) 41.f6 (threatens 42.Bg7+ Kh7 43.Qh5+) 41... Qe8 42.Qxc4, threatening f7, looks very good for White. A.2) 35... Ke7 36.Rxg7+ and mate next.
A.3) 35... Re6 36.fxe6+
A.3.a) 36...Kf8 37.Qxd6+ Kg8 (37... Ke8 38.Rxg7 wins) 38.Qd8+ Kh7 39.Qe7 Qd7 40.Rxg7+ wins decisive material. A.3.b) 36... Kg8 37.e7+ wins.
A.3.c) 36... Ke7 37.Rxg7+ wins.
A.3.d) 36... Ke8 37.Rxg7, with many threats (Qa8#, Qxd6, Qh5+), wins. B) 34... c6 35.Rd7+ Nxd7 (35... Re7 36.Rxg7+ Kxg7 37.Rxe7+ and mate next) 36.Qxd7+ Re7 37.Rxg7+ Kxg7 38.Qxe7+ followed by Bxh6 and Qg7#. C) 34... Re7 35.Qd5+ Kf8 (35... Ke8 36.Rd8#) 36.Rxf6+ Ke8 (36... gxf6 37.Rg8#) 37.Qg8+ Kd7 38.Rxg7 looks winning. |

| | agb2002: According to DroidFish 41.f6 is a blunder which only achieves a draw, while 40.Qh4 wins. I saw this move and spent a long time trying to make it work unsuccessfully. |
