| May-04-16 | | diagonalley: yep - 24... NxKNP wins... interesting position, a few continuations to calculate and a good wednesday puzzle |
|
| May-04-16 | | agb2002: The material is identical.
White threatens 25.hxg6.
Black can create a double threat, a killing double check with rook and knight and an attack against the white queen, leads to 24... Nxg5: A) 25.Bxd7 Nh3+ (or 25... Nf3+ 26.Kh1 Rg1#) 26.Kh1 Rg1# (or 26... Nxf2#). B) 25.hxg6 Nxh3+ 26.Kg2 Bxb3 - + [Q vs R].
C) 25.Kh1 Nxh3 26.hxg6 (26.Qc2 Rg1#) 26... Bxb3 - + [Q vs R]. D) 25.Bg2 Nh3+ 26.Kh1 Rxg2 27.Kxg2 Bxb3 - + [Q vs R]. E) 25.Bxg5 Rxg5+ 26.Kh1 (26.Bg4 Rxg4+ 27.Nxg4 Qxg4+ 28.Ng3 Bxb3 wins; 26.Bg2 Bxb3 wins) 26... Qxh3 27.Ne(g)3 (else 27... Qg2#) 27... Bxb3 wins. F) 25.Ng3 Nxh3+ followed by 26... Bxb3 wins. |
|
| May-04-16 | | morfishine: Took some counting before I finally figured out <24...Nxg5> wins in all variations; This one is mostly being able to add up material after all possible exchanges and Black always comes out ahead: he's always capturing with tempo |
|
| May-04-16 | | gofer: <Queen-Sac> time! Yeeehhaa!!! <24 ... Nxg5!>
White has to avoid mate...
25 Bxd7 Nh3++/Nf3++
26 Kh1 Rg1#
but also doesn't want to lose its queen.
25 Bg2 Nh3+
26 Kh1 Nxf2+
27 Kg1 Bxb3 
The only sensible defence seems to be...
<25 Bxg5 Rxg5+>
<26 Ng3 Qxh3>
Black threatens Rxf2 in the future, so the queen must move to either c2 or b2 to
protect Pf2. Qc2 also protects Pe4...
<27 Qc2 Bxh5>
click for larger viewBlack has won B + 2P and has a huge attack with Bf3 or Rf3, white has to defend f3, but can't do that with Qc2 as that is protecting against Rxf2. <28 Re3 Rf4!>
click for larger viewBlack doesn't need control of f3! <29 ... Rh4> is deadly! ~~~
Yep... |

| May-04-16 | | jith1207: You all got it wrong. <tpstar> got the solution or answer to today's Question right. You win the day, Sir. On a side note, is this All Blacks week? |
|
| May-04-16 | | Elrathia Kingi: I personally find the smothered mate, 26...Nxf2# more aesthetically pleasing, but there is no accounting for taste, and results matter more than beauty at the chess board. |
|
| May-04-16 | | clement41: I prefer the ...Nh3++ line as it enables black to ask his opponent "now choose your death".
A nice double check, where both checking pieces are en prise on their square but thanks to the magics of double check are nevertheless immune |
|
| May-04-16 | | Cheapo by the Dozen: Wednesdays can be cool.
The basic idea is that 24 ... Nxg5 threatens mate in 2, uncovers an attack against the h3 bishop, and also uncovers an attack against the queen. However, after the move Black's queen and rook are both en prise. The only defense I see that has any hope of both stopping mate and maintaining material parity is 25 Bg4, so let's focus on that. 24 ... Nxg5
25 Bg4 Nf3+
Now
26 Nxf3 Qxg4+ and mate next
26 Kh1 (Kg2 looks even worse) Bxb3 and Black can snag the e1 rook next. I didn't check to see whether Black can mate instead. |
|
| May-04-16 | | eblunt: < Cheapo > 25 Bg4 then 24 ...Bxb3 wins immediately. |
|
| May-04-16 | | alfiere nero: Well, I saw this one right away, but never believed white would take the black queen and fall in the trap. |
|
| May-04-16 | | alfiere nero: Oh, I see, she was only nine years old. |
|
| May-04-16 | | DarthStapler: I kept thinking Nf4 |
|
| May-04-16 | | saturn2: 24..Nxg5 threats a) QxBh3 followed by mate Qg2 and b) Nf3 followed by mate Rg1. |
|
| May-04-16 | | CHESSTTCAMPS: In this middle-game position, material is even. It is apparent that white's pawn advances have backfired: white is behind in development and the castled position is severely weakened on the g-file. White threatens hxg6 and may be counting on 24... Rxg5+ 25.Bxg5 in view of the trapped position of the rook. But white's assumption that the Ne6 is pinned is misplaced: 24... Nxg5!! unleashes two discovered attacks (and prepares a third discovered attack!), forcing mate quickly or winning the queen: A.25.hxg6 (or Ng3, Ng4, Ne3, Nd2) Nxh3+ followed by 26.K moves Bxb3 leaves black up a queen for a rook and a winning king-side attack, with the pleasant choice of Rxf2 or Nxf2. B.25.Bxg5 Rxg5+ 26.Kh1 Qxh3 and white must give up the queen to stop 27... Qg2#. C.25.Kg2 Qxh3+ 26.Kg1 Bxb3 wins.
D.25.Kh1 Nxh3 followed by 26... Bxb3 if white does not defend 26... Rg1# E.25.other Nxh3+/Nf3+ 26.Kh1 Rg1#
Time for review... |

| May-04-16 | | mel gibson: Saw it in 3 seconds - must have been a Monday puzzle?
Why would white be so stupid as to take the Queen?
In any case white is in big trouble & loses. |
|
| May-04-16 | | kevin86: A Finish similar to the Reti-Tartakower trap in the opening. Black's pieces are BOTH en prise, but both can be NOT TAKEN at once. |
|

 | | gawain: Spotted that the final position could be a mate delivered by the rook at g1, protected by a knight--but had trouble visualizing how Black would bring it about. More and more often I find myself needing an actual chessboard. |

| May-04-16 | | alfiere nero: <Elrathia Kingi> good point! |

| May-04-16 | | RandomVisitor: White was doing fine up to move 22 when Ne3 was likely better in a complicated position

| May-04-16 | | dufferps: Caoili might have made it more interesting with 25. bxg5. I would expect 25... Rxg5+ 26.Ng3 Qxh3. Am I missing a quick checkmate? Still Black's game, I think, but not that quick. |
|
| May-04-16 | | dufferps: I should have mentioned ... After 25.Bxg5 Rxg5+ 26.Ng3 Qxh3. white would follow with advancing his pawn to c4 -- letting black's bishop capture his queen would not be a good trade, especially now that he's lost both Bishops. |

| May-04-16 | | gabriel25: Considering is Wednesday and black kind of packed back, the first attacking move of black I looked, solving with a queen sacrifice and three beautiful N moves, its not going to be cooked, but i saw Ng2 and didn't see the rook one.
As puzzles go its beautiful but too easy
I love knights, with pawns on both sides the board bishops are better but on one side the knight will have the bishop for lunch. Is there such a thing as an over 90 chess tournament? an over 80 would do too but the over 70 is probably full of masters. |
