 | | geezerbloke: I got it relatively quickly, which slightly repaired my ego after getting duffed up badly at the club last night 0-3 (and i was lucky to get 0), it is a new day! |
|
| Nov-17-20 | | newzild: <<Walter Glattke>: Ah, classic mate-in-three 33.Rg8+ Rxg8 34.Qxf6+ Rxf6 35.Bxf6#> Unfortunately, 35. Bxf6+ isn't mate because of 35...Rg7. |
|
| Nov-17-20 | | Brenin: <Walter Glattke>: Unfortunately, the "classic mate-in-three" 33 Rg8+ Rxg8 34 Qxf6+ Rxf6 35 Bxf6 fails to 35 ... Rg7 36 Bxg7+ Kg8, followed by 39 ... Bxg3+, leaving Black with Q vs B. Once I saw this, the alternative 33 Qxf6, with mate to follow, soon came to mind. |
|
| Nov-17-20 | | Walter Glattke: I see, my first view at the morning looking at the first website, was not enough, playing this at the board there is no mate by Rg7, I just neeed my chessboard, the eyes are not enough for that. So, I found a mate-in-six then, but, of course, in the match the mate or resign was always quicker. |
|
| Nov-17-20 | | Brenin: Why not 22 Ne7+ and 23 Nc6, winning the exchange? And why not 24 ... Bxb4 25 axb4 Rxb4 and White's Q is overloaded, e.g. 26 Qc3 (threatening mate on g7) Rxb2 or 26 Qxc5 Rxb2 (not 26 ... dxc5 27 Rxd8+, with mate), leaving Black ahead in material. And why not 26 ... Bxe3+? Or 30 Rxd6? A very puzzling game. When Black eventually took the P on e3, it was too late, and 31 ... Rg8 was required. |

| | Oxspawn: I had to play it through twice as I did not quite believe it the first time.
I got excited by Rb7 but, sadly, it cannot then defend the rook on g3. Without boasting, I give myself credit for finding innovative ways to lose. |
|
| Nov-17-20 | | morfishine: <FSR: Doesn't seem easy to me. I didn't get it. A good trick to know> An admirable admission from a player of your class |
|
| Nov-17-20 | | WorstPlayerEver: Very easy. |
|

 | | perfidious: More difficult than typical Tuesday fare, it is not that hard overall; but foreseeing such possibilities before one has got there is the mark of the strongest players. One aspect which is easy to forget in preliminary analysis is that the rook at g3, while pinned throughout the finish, still exerts a baleful influence over the enemy position. |
|
| Nov-17-20 | | Vermit: The first thought is that because of the pin, White needs to check. But then you see this doesn't lead anywhere, so you look for a move that makes the threat of Bxg3+ null and void. So by that process only Qxf6 fits the bill and leads to mate in all lines. It is a fitting illustration of how a double check neutralises all other possibilities. |
|
| Nov-17-20 | | WorstPlayerEver: PS weird, this is a pretty straightforward puzzle. Needed some secs for 34... h5
Curious. |
|
| Nov-17-20 | | Nosnibor: Found key move within one minute. Clever play. |
|
| Nov-17-20 | | Brenin: After 32 Rxg7, Black's only hope of survival seems to be to give up the B and force Qs off with 32 ... Bg1+ 33 Kxg1 (33 Kh1? Bf2!) Qe1+ 34 Qxe1 Rxe1+ 35 Kh2. Now Black is a B down, with a dreadful position, e.g. 35 ... Re6 36 f5 or Rf7 and mate must follow soon. |

 | | Messiah: It was almost as easy as coming up with a better pun than 99% of the puns outta there on GOTDs. |
|
| Nov-17-20 | | TheaN: Somewhat common long diagonal pressure leading to an unavoidable windmill mate. After <33.Qxf6 #4> White sets this up and cannot be prevented. 33....Rxf6 34.Bxf6 #2 the key is that it doesn't matter per se if Black includes this, as all the threats are still similar. In fact, this is a move shorter to mate. 34....Bxg3+ 35.Rxg3#, whereas 35.Rg8# is also a threat. Creating air with 34....h5/h6 fails to 35.Rf7# (any from a-f). 34....Qxg2+ delays mate by one more move. Practically if Black foregoes Rxf6 he has a few more spite checks with Re6, but that's all. Best is -#4 <33...Qxg2+ 34.Kxg2 Re2+ 35.Kh1 Rh2+ 36.Kxh2 Be5 37.Rg8#>. |
|
| Nov-17-20 | | Cheapo by the Dozen: I solved it, but with enough difficulty that I'm not sure I would have seen it over the board. The key point is that once White has captured on f6, he's threatening DOUBLECHECK and mate. So all defenses that do not involve ... Bxg3+ fail in that they at best stop one of the two mates (generally the diagonal one). And the recapture on g3 is a discovered check that quickly mates as well. The trick, other than seeing it in the first place, is not to get confused between the double and discovered checks. While similar, they aren't quite the same thing!! |
|
| Nov-17-20 | | Cheapo by the Dozen: The engine thinks Black was fine with 31 ... Rg8, and indeed ahead at -0.38. Instead he blundered into the puzzle combination. |
|
| Nov-17-20 | | DrGridlock: <The trick, other than seeing it in the first place, is not to get confused between the double and discovered checks. While similar, they aren't quite the same thing!!> Every double check is a discovered check.
Not every discovered check is a double check. |

| | scruggs: Bishop sacrifice on Monday. Queen sacrifice on Tuesday. I've got to get my days straight |
|
| Nov-17-20 | | cormier: 22...Bxd5 is possibly not good, giving away the Bs pair |
|
| Nov-17-20 | | cormier: 22...Qh4 maybe |
|
| Nov-17-20 | | Brenin: <cormier>: The N on d5 was a much stronger piece than the B on e6, since it threatened Ne7+ followed by the triple fork Nc6, for example. It had to go. After 22 ... Bxd5 23 Rxd5 (Qxd5 is no better) Qe6, or even 23 ... Qe2 24 Rf2 Qe1+ 25 Rf1 Qe2, Black was doing fine. He would have been doing even better after 24 Qxc4 Bxb4 25 axb4 Rxb4. |
|
| Nov-17-20 | | mlskdney: queen to take the pawn on f6 maybe |
