 | | Phony Benoni: Looks like a sacrifice on a4 is in order/ Let's try the more forcing <36. ..Rxa4+> first. 37.Kb2 Ra2#, so it's got to be <38.bxa4 Qxa4+ 39.Kb2 Qa2+ 40.Kxc3 Rc8+> and it's getting nasty for White. 40.Kd4 Qc4#
40.Kb1 Rxc4+ 41.Kb5 Qxa4#
40.Nc7 Rxc7+ and as before, the king never gets to the flight square on d5. And the only thing left is tolearn what I missed. |
|
| Feb-07-19 | | ChessHigherCat: Rook sac Thursday: 36...Rxa4+ 37. bxa4 Qxa4+ 38. Kb2 Qa2+ 39. Kxc3 Rc8+ 40. Kd4 Qc4# |
|
| Feb-07-19 | | ChessHigherCat: <PB> was not only faster but got all the variants: waaah! |
|
| Feb-07-19 | | ChessHigherCat: Even 32...Rc4!? wins! (-2.84) |
|
| Feb-07-19 | | Walter Glattke: I did not see from the puzzle position, that KxN will be answered with Rc8+, many players would get a draw with 36.-Nxd5 37.Rxd5 Rxa4+ 38.bxa4 Qxa4+ 39.Kb2 Qb4+ or 39.Kb1 Qb2 40.Qxd1+ with black advantage |

 | | An Englishman: Good Evening: Poor White. His 35.Ne7 actually forced Black to set up the winning combination. |
|
| Feb-07-19 | | lost in space: Got that but it Tok me a while to calculate to mate or so close to mate that I was sure that it will be mate. Nothing to add what was said already. |
|
| Feb-07-19 | | goldfarbdj: I think 42. ... Qa6 is a prettier mate than Qa4. |
|

 | | al wazir: I didn't get it, even though I was sure the key had to be 36...Rxa4+. The best I could find was 36...Nxd5 37. Rxd5 b5 38. Qd2 Qxd2 39. Rxd2 bxa4 40. bxa4 Rxa4+ 41. Kb2 d5, with a measly 1-♙ advantage -- and I doubt that black can keep it. |
|
| Feb-07-19 | | agb2002: Black can start a mating attack with 36... Rxa4+ 37.bxa4 (37.Kb2 Ra2#) 37... Qxa4+ 38.Kb2 Qa2+ 39.Kxc3 Rc8+: A) 40.Kd4 Q(R)c4#.
B) 40.Kb4 Rc4+ 41.Kb5 Qa4(6)#.
C) 40.Nc7 Rxc7+ 41.Kb4 (41.Kd4 Qc4#) 41... Rc4+ 42.Kb5 Qa4(6)#. |
|
| Feb-07-19 | | DonChalce: unlike the puzzle, the game was pretty good. |
|
| Feb-07-19 | | stacase: Ha! White's Queen & Two Rooks just sit there and watch. |
|
| Feb-07-19 | | Cheapo by the Dozen: The key to this one, after the initial sacrifice idea, is seeing how devastating the checks on c4 are. Pretty easy for a Thursday. |
|
| Feb-07-19 | | Mayankk: Got it. And so nice to see the entire mating combination being played out in the game. In most GM games, we pitifully stop 100 moves before a forceful mate, since the GMs can calculate it all while we mere mortals struggle to figure out how exactly. So it’s refreshing to see it actually play out. |
|
| Feb-07-19 | | patzer2: Knowing it's a moderately difficult Thursday puzzle, I solved this one (36...?) easy enough. Now if only someone would whisper in my ear that I have a winning King hunt when I'm playing OTB, I'd easily be able to pull off combinations like this in my own games. |
|
| Feb-07-19 | | bubuli55: 42...Qa6# like |

 | | scormus: drat, didn't quite get this one. Missed 40 Nc7 ;) |
|
| Feb-07-19 | | patzer2: So where did White go wrong? The losing move appears to be 19. Nc4?, leaving the White e-pawn unprotected and giving Black a practically won game after 19. Nc4? Bxb2+ 20. Kxb2 Nxe4 -+ (-2.04 @ 33 ply, Stockfish 10). Instead, protecting the e-pawn with 19. Rhe1 = (0.00 @ 31 ply, Stockfish 10) holds the position level. Earlier, White missed a chance to secure a strong advantage with 9. Ng5 Qe7 10. Nxe6 Qxe6 11. Bc4 ± (+1.48 @ 29 ply, Stockfish 10). Instead, 9. e4?! f4 gave Black sufficient counter play to find a way equalize and steal the initiative after 10. Ng5?! (better is 10. Nc4 ⩲) 10...Bg8 = to ⩱. |

| Feb-07-19 | | OrangeTulip: K McDonald had a farm hihahihaho, and on that farm he had a horse.... |
|
| Feb-07-19 | | mel gibson: It's an easy puzzle.
It's mate in 6. |
|
| Feb-07-19 | | Sokrates: <mel gibson: It's an easy puzzle.
It's mate in 6.>
Yeah, like an old club player used to say, "It's a plain and simple 12 moves combination". |
|
| Feb-07-19 | | malt: 36...R:a4+ 37.ba4 Q:a4+ 38.Kb2 Qa2+
39.K:c3 Rc8+ 40.Kb4
(40.Kd4 Qc4# )
40...Rc4+ 41.Kb5 Qa4# |

<36....?>
Mate time.
<36....Rxa4+ 37.bxa4 (37.Kb2 Ra2# / 37.Qa3 Qxa3#) Qxa4+ 38.Kb2 (Qa3 Qxa3#) Qa2+!> the actual key <39.Kxc3 Rc8+ 40.Nc7> similar without interposing <40....Rxc7+ 41.Kb4 (Kd4 Qc4#) Rc4+ 42.Kb5 Qa4/6#>. Plain, but not necessarily simple. |
|
| Feb-07-19 | | saturn2: I saw 36...Rxa4+
37. bxa4 (Qa3 or Kb2 is rubbish) Qxa4+ 38. Kb2 Qa2+ 39. Kxc3 Rc8+ 40. Nc7 Rxc7+
with various mates. |
|
| Feb-07-19 | | mel gibson: <Yeah, like an old club player used to say, "It's a plain and simple 12 moves combination".> No - 12 moves is hard - 6 moves in this case was easy.
The King had hardly anywhere to go.
This was a Monday puzzle. |
