| Nov-19-14 | | patzer2: Forgot I'd seen this combination seven years ago. So this Wednesday puzzle took me a while to recall. The main point is 20. Bxe6!! fxe6 21. Bxf6  yields two possible winning double attacks: If 21...Bxf6 22. Qh5+, then White gets mated after 22...Kf8 23. Qf7# or drops
the Queen to a Knight Fork after 22...Ke7 23. Qxh7+ Kd6 24. Nf7#. If 21...Qxd4 (as in the game), then White gets mated after 22. Qh5+ Kf8 23. Qf7# or drops the Queen to a Rook Skewer after 23...Kd8 24. Rd1 . |
|
| Nov-19-14 | | diagonalley: darn... i didn't find the knight fork, so couldn't make it work :-( |
|
| Nov-19-14 | | Granny O Doul: Why is "doozy" spelt this weird way? |
|
Nov-19-14
 | | Richard Taylor: The fork works if she captures on h7 which was the trick but Qf7+ looks tempting also. |
|
| Nov-19-14 | | agb2002: White is one pawn down.
Black threatens 20... Qxd4.
White would deliver a nice mate if 20.Qf5 exf5 21.Bxf7+ Kf8 22.Bh6# were a forced line. However, this suggests 20.Bxe6, threatening that mate in two: A) 20... fxe6 21.Bxf6
A.1) 21... Bxf6 22.Qh5+ Ke7 (22... Kf8 23.Qf7#) 23.Qxh7+ Kd6 (23... Ke(f)8 24.Qf7#; 23... Bg7 24.Qxg7+ Kd6 25.Nf7+ is even worse for Black) 24.Nf7+ Kd5 25.Nxd8 Rxd8 26.Qxb7 + - [Q+P vs B]. A.2) 21... Qc7 22.Qh7+ Kd8 23.Qf7 Qd6 (23... Bxf6 24.Qf8#) 24.Qf8+ Kc7 25.Qxe7+ Qxe7 26.Bxe7 + - [N]. A.3) 21... Qd6 (or 21... Qxd4) 22.Qh7+ Kd8 23.Nf7+ wins the queen. A.4) 21... Qd5 22.Bxe7 Kxe7 23.Qf7+ Kd8 24.Qxb7 wins a piece. A.5) 21... Qb6(a5) 22.Qh5+ Kd8 23.Bxe7+ wins a piece or delivers mate (23... Kxe7 24.Qf7+ Kd6(8) 25.Qd7#. B) 20... Qd6 21.Bxf7+ Kd8 22.Nc4 Qb4 (22... Qxd4 23.Rd1 wins the queen) 23.Bxf6 wins a knight and a pawn. |

| Nov-19-14 | | morfishine: Took me awhile to sort out the correct move-order:
<20.Bxe6> best
20...fxe6 21.Bxf6 Bxf6 22.Qh5+ Ke7 23.Qxh7+ Kd6 24.Nf7+ forking the Queen ***** |
|
| Nov-19-14 | | starry2013: I assume there's a checkmate. I ended up trying a double sacrifice with Bf6 and Nf7, while I had plenty of pressure I couldn't 'bring home the bacon'. |

 | | tobywan: <Granny O Doul> Because "Duesy" is the correct (well, that's an odd adjective to apply; at least it's the original) spelling. "It's a Duesy" was originally an ad slogan for the Duesenberg automobile. Of chess I am largely ignorant, but ads crowd my brain. |
|
| Nov-19-14 | | Castleinthesky: Didn't get it, I chose Ba6. |

|
| Nov-19-14 | | kevin86: Black can lose the queen...or be mated! |
|
| Nov-19-14 | | gofer: Well this is obviously a case of <remove the defender>, but there are 2 (Pe6 and Nf6) so which one to remove
first. I think we can probably choose, but I prefer to threaten mate rather than go for the knight. <20 Bxe6 ...>
Some moves lose immediately...
20 ... N anywhere
21 Qxf7#
20 ... c4
21 Bxf7+ Kf8
22 Bh6#
But, <taking Be6 seems to lead to disaster>... 20 ... fxe6
21 Bxf6 ...
The bishop is poisoned and cannot be taken...
21 ... Bxf6
22 Qh5+ Ke7 (Kf8 Qf7#)
23 Qxh7+! Kd6
24 Nf7+ winning Qd8 and Bb7
...but, there are lots of alternatives to taking the bishop.
The problem for black is that not taking the bishop implies
moving the queen to provide an escape square for the king
and at the same time the queen must protect Be7.
21 ... Qd6
22 Qh5+ Kd8
23 Nf7+
21 ... Qa5/Qb6/Qb8
22 Bxe7
21 ... Qc7
22 Qh5+ Kd8
22 Qf7!
21 ... Qc8
22 Bxe7+ Kxe7
23 Qf7+ Kd8 (Kd6 24 Nc4+ Ke5 25 Qh5+! mating)
24 Qf8+ Kc7
25 Qe7+ Kb8 (Kb6 28 Rb1+ Ka6/Ka5 29 Qa3#)
26 Nd7+! Kc7
27 Nc4+ Kb8 (Kb6 28 Rb1+ Ka4 29 Nxb7+ mating)
28 Rb1 mating
Unfortunately for black, <not taking Be6 seems to lead to disaster too>. The
queen must move to provide an escape square for the king after Bxf7+. 20 ... Qc7
21 Bxf7+ Ke8
22 Bxf6
The most resilient moves seems to be...
<20 ... Qd6>
<21 Bxf7+ Kd8> (Kf8 Bh6#) <22 Nc4! >

Well, black made that a little easy! |
|
| Nov-19-14 | | heatmiser: hello? |
|
| Nov-19-14 | | BOSTER: I've never heard such word like "Excelsior".
Shame. Now I have to give you the pos. as a fee for nice lesson.
click for larger view Black to play.
Here black invented the unique trap. |
|
| Nov-19-14 | | Zhbugnoimt: BOSTER: Black goes 1...Qe7!! 2.fxe7 Bg7 0-1 |
|
| Nov-19-14 | | sycophante: Did someone else go for 20.Rb1? (my engine likes it very much)
But after Black's 20...Rb8, I still had to find 21.Bxe6 anyways. |
|
| Nov-19-14 | | Whitehat1963: Surprisingly got a Wednesday puzzle pretty quickly. |
|
| Nov-19-14 | | johnlspouge: @<Domdaniel>: Thanks. It is worth mentioning that AE Housman parodied "Excelsior" with "The Shades of Night", another excellent poem. [ http://allpoetry.com/Excelsior:-the... ] |
|
| Nov-19-14 | | patzer2: Should Black not resign and instead continue with 23...Kd8, White has the pleasant choice between 24. Rd1 winning the Queen with a Rook skewer or 24. Nf7+ followed by 25. Bxd4 winning the Queen via a discovered attack with check. |
|
| Nov-19-14 | | whiteshark: Cudn't find it in blitz mode. :( |
|
| Nov-19-14 | | TheBish: Zsuzsa Polgar vs V Dimitrov, 1984 White to play (20.?) "Medium/Easy"
20. Bxe6! fxe6
Not 20...Qxd4 21. Bxf7+ Kd8 (or 21...Kf8 22. Bh6#) 22. Rd1, winning the queen. 21. Bxf6 Bxf6
Otherwise (like after a queen move) 22. Qh5+ is coming anyway, with a winning attack. 22. Qh5+ Ke7
Of course if 22...Kf8? 23. Qf7#.
23. Qxh7+! (Saving f7 for the knight!) Kd6
Otherwise 24. Qf7 mates, or in the case of 23...Bg7 24. Qxg7+ just wins more material. 24. Nf7+ forks king and queen, winning. |

| | Bubo bubo: After a single line yesterday it seems as if we have a bunch of variations today: I propose 20.Bxe6. As White threatens mate in two, Black must accept the sac willy-nilly: 20...fxe6 21.Bxf6! Black must not recapture, since 21...Bxf6 22.Qh5+ Ke7 23.Qxh7+ Kd6 24.Nf7+ loses the queen. In order to parry the mating threat of Qh5+, Black has to move his queen (21...Kf8 22.Qh5 is futile). Most of the moves are easily refuted: A) 21...Qxd4/Qd5/Qd6 loses the queen after Qh5+ and Nf7+. B) 21...Qc7 22.Qh5+ Kd8 23.Qf7! wins the Be7, as Bxg5 fails to Qf8#. C) 21...Qb8 22.Qh5+ Kd8 23.Bxe7+ wins at least a piece, as 23...Kxe7 fails to 24.Qf7 with mate next move. But alas I don't see a decisive continuation after 21...Qc8! Of course 22.Qh5 Kd8 23.Bxe7+ Kxe7 24.Qxh7+ wins a pawn and leaves Black in a poor position, but this can hardly be the solution... It seems as if Wednesday is the new Friday, at least for me: I failed last week, and so I did today... :-( |

 | | gawain: Not that anyone will still be looking at this kibitzing, but... According to some sources the word "doozy" predates the Duesenberg car by a few decades. The OED is reported to favor derivation of doozy from "daisy" an English slang term for something remarkably good. I don't have an OED handy but take a look here. http://www.worldwidewords.org/qa/qa...
Seems likely to me that the Duesenberg ads were making a nice wordplay on the similarity of Duesy to the pre-existing doozy. Oh yes, and I like the Polgar game, Doozy or Duesy as it may be. Very nice finish, |
|
| Nov-21-14 | | Granny O Doul: Thanks toby, that's interesting. Though looking it up now at "world wide words" the "doozy" spelling seems to go back further. Of the suggested etymologies given there, I like the "Eleanora Duse" one best, though that is not to say that I believe it. |
|
| Dec-08-22 | | Chesgambit: Similar to Eric Rosen's 4 Queen's but White is better here. https://lichess.org/fPwHcznw/black#25 Bxg7 was better here. |
