 | | OhioChessFan: <patzer> Yes, I tried the 28. Nxc4 line, with the idea of the 2 rooks chasing the Black Q up and down the c file. Qxc3+ is Black's answer, and the Q can give up the defense of the c8 Rook. Reminded me a little of the draw Kaspy missed against Blue. |
|
| May-26-05 | | mgm329: Englishman: interesting--I wasn't aware you were the "teacher" responsible for deciding who gets credit on this "assignment"; obviously, nobody would play 28. Qd8+ unless they did see 31. h5. |
|
| May-26-05 | | Marius: <2ndNature >
yes, thanks
:) |
|
| May-26-05 | | fenno: This took some time to solve, but on the other 28. Qd8+ was the only try that looked brutal enough. Then I stopped for a while because somehow I thought the position after 28... Rxd8 29. Rxd8+ Kh7 like this: "What black now do to prevent Rbb8?" The answer is of course: "Nothing, because it is not black's turn." and when I realized that the rest was clear. Hmm... That brings to my mind that humans actually use the "null move"-concept on purpose in similar way the best chess programs do. We often think like this: "If the opponent does nothing (=null move) to prevent this move, then..." |
|
| May-26-05 | | Shokwave: This was pretty easy for me today...first thing I looked for was getting heavy pieces onto that back rank, which meant moving the "capture" square from the queen-protected c8 to somewhere else. Qd8+ jumped right out at me. The rest was just mechanics, checking the line out and seeing if the king could escape. |
|
| May-26-05 | | JohnBoy: Indeed, <gidguy, dzanone>, why did black not play 22...Qxc3+? Black can follow up any king move with the aggressive 23...Nxd4. White cannot afford to capture the e6 pawn with 24.Nxd4 Qxd4 25.Rxe6 as black can pick up the b1 rook with check by a double attack. How does white justify the move? Maybe just 22...Qxc3+ 23.Kf1 Nxd4 24.Nxd4 Qxd4 25.Kg1, and the white king is sheltered while black is playing a rook down. |
|
| May-26-05 | | kevin86: Just checking: is the sequel--28...♖xd8 29 ♖xd8+ ♔h7 30 ♖bb8 g5 31 h5 ♖g6 32 ♖h8+ ♔g7 33 ♖bg8# right? |
|
| May-26-05 | | Milo: 31...Rg8, Kevin |
|
| May-26-05 | | YouRang: Rats. Qd8+ was the first move I looked at, but once again, I dismissed it after failing to see the further threat of Rb8 and h5, etc. |
|
| May-26-05 | | farrooj: what's the first thing you try? Sac your queen. nice find by chessgames, two Xrays in a week. |
|
| May-26-05 | | kevin86: Milo-black can avoid the mate but must give up a second rook-and soon after,his queen. Thus an easy win for Chandler. |
|
| May-26-05 | | midknightblue: Before looking at the answer I will give forth my suggested solution...and risk looking like a fool, if this Queen sac for some reason does not work. 28 Qd8 Rxd8 (or if Kh7 then RxR and win). 29 Rxd8 Kh7 30 Rb8 g5 31 h5 and should be a forced mate to follow, which black can delay but not avoid. I am trying to do this in my head to improve. If my answer makes no sense I apologize. |
|
| Jun-19-19 | | sudoplatov: Fairly easy. Punish Black for Fianchettoing his Rook. |
|
| Jun-19-19 | | agb2002: White is a pawn ahead.
Black's back rank is weak and the black king and the rook on g2 lack mobility. This leads to consider 28.Qd8+ Rxd8 (28... Kh7 29.Rxc8 wins) 29.Rxd8+ Kh7 30.Rbb8: A) 30... Rg8 31.Rxg8 f5(6) (due to 32.Rh8+ Kg7 33.Rbg8#) 32.exf6 g5 33.h5 and mate in two. B) 30... g5 31.h5 as above (31... Rg6 32.Rh8+ Kg7 33.Rbg8#). |
|
| Jun-19-19 | | Cheapo by the Dozen: Yet another fun one!
The main try is:
28 Qd8+ Rxd8
29 Rxd8+ Kh7
30 R1b8 and check whether Black can do anything useful with his tempo. It turns out that he can't. Attempts at making horizontal Luft fail because they allow the e5 pawn to get to f6, while the ... g5 attempt at making vertical Luft fails to h5. |
|
| Jun-19-19 | | saturn2: My line was 28. Qd8+ Rxd8 29. Rxd8+ Kh7 30. Rbb8 g5 31. h5 |
|
| Jun-19-19 | | stacase: Dunno, sometimes you see these things right away, and other times it's a "Why didn't I see that?" senior moment. 28.Qd8+ was as obvious as the north end of a south bound goat. |
|

 | | perfidious: <North end of a south bound goat> Thought never occurred to me. |
|
| Jun-19-19 | | stacase: <perfidious ... Thought never occurred to me.> Not yer basic chess term. But you kin Google it. What follows 28.Qd8+ isn't as obvious, but obvious enough to cause Black to tip his King over. I usually don't figure these puzzles out to the mate, indeed lots of them continue on many moves before defeat is obvious. On this one it looks like there's a mate in a few moves and in order to stave it off, Black must lose his Rook and then it follows - the game. |

| Jun-19-19 | | mel gibson: I didn't see it yet after I saw
the solution it seemed so easy.
(If Black takes the White Queen it's mate in 8.)Stockfish 10 says mate in 15:
28. Qd8+
(28. Qd8+ (♕f6-d8+ ♔g8-h7 ♖b8xc8 ♕c6xc8 ♕d8xc8 ♖g7-g8
♕c8xa6 ♘c4xe5 d4xe5 ♖g8-e8 ♖b1-b7 ♔h7-g8 ♕a6-d6 ♔g8-g7 ♕d6-d7 ♖e8-f8 ♘d2-f3
g6-g5 ♕d7-e7 g5xh4 ♕e7-f6+ ♔g7-g8 ♘f3-d4 ♔g8-h7 ♘d4xe6 ♖f8-g8 ♕f6xf7+
♖g8-g7 ♕f7xg7+) +M15/63 222) |

 | | Richard Taylor: I solved this quite quickly. It is probably a forced mate. I cant see a way of avoiding mate for Black... Fairly straightforward.
Murray Chandler was born in NZ. He doesn't play these days but I think he still manages his business Gambit Books. |

 | | fredthebear: <Richard Taylor> Good to see your comments, as always. (Haven't read any of your remarks in awhile.) Please keep 'em coming when you can! |
|

 | | ChessCoachClark: One of the best examples of an X-Ray attack that I've seen in a quite a while! An excellent demonstration for my students, definitely. |
|
| Jun-19-19 | | malt: I did not see it, I had discarded 28.Qd8+
Looking at 28.Ne4 de4 29.d5 which did not work |
