|Jan-05-17|| ||saturn2: First i saw all pieces are on the board only a lot of pawms eliminated. So attack on open lines and diagonales can come.
I saw the queen sacrifice for R+N. and the foolwing attack on h2 by Nf3. Also the white back rank is weak. White would have to give the queen for only one piece not compensating the original black sacrifice.|
|Jan-05-17|| ||saturn2: I correct my above posting. <queen sacrifice for R+B> is right.|
|Jan-05-17|| ||morfishine: <25...Qxd5> Otter do it aiming for the suffocation cornered theme with R+B+N|
|Jan-05-17|| ||Sularus: queen sac and then a R+N mating theme|
|Jan-05-17|| ||agb2002: Black is one pawn down.
White threatens Bxf7+.
The defenseless rook on f2 suggests 25... Qxd5+ 26.Nxd5 Rxf2:
A) 27.Ng3 Nf3 with the triple threat Bg2#, Rxh2# and Rxd2 wins decisive material. Also looks winning 27... Bg2+ 28.Kg1 Bxd5 29.Ne4 Bxe4 30.dxe4 Rxd2 or 28... Rxd2 29.Qxd2 Nf3+ 30.Kxg2 Nxd2 31.Rb2 Nf3.
B) 27.Qb3 Nf3 as above. White doesn't seem to have a useful discovered check, for example, 28.Ndf4+ Kh7 29.Nxh3 Rxh2#.
C) 27.Nd4 Bg2+ 28.Kg1 Bxd5 and the threat Rg2+ looks winning (29.Nf4 Rxd2).
D) 27.Ne3 Nf3 28.Nf1 Bxf1 wins.
E) 27.Ndf4 Nf3 28.Qg1 (28.Qb3+ Kh8 29.Qb8 does not work due to the knight on f4) 28... Nxg1 29.Kxg1 Rf3 - + [R+B vs N+P].
F) 27.Nef4 Nf3 as above.

By the way, the result of this game is, as I read it, is: "0-1".>
But who knows what the result said in 2004. ;-)
|Jan-05-17|| ||Willber G: I can't find a winning continuation for black after 27.Qg1|
|Jan-05-17|| ||saturn2: <Wilbert G> 27..Rf1 white has to give queen for rook|
|Jan-05-17|| ||zb2cr: Saw this one relatively quickly.|
|Jan-05-17|| ||Willber G: <saturn2: <Wilbert G> 27..Rf1 white has to give queen for rook>|
Oops, I miscounted when going through that line, black ends up with an extra piece which should be enough.
|Jan-05-17|| ||YetAnotherAmateur: <stst> I'm glad I wasn't the only one looking at 25. ... Nxd3|
I went with a somewhat different line, though for 26. Nxd3, which may be more forcing:
26. Nxd3 Qxd5+
A1) 27. Rf3 Qxf3+ 28. Kg1 Qg2#
A2) 27. Kg1 Rxf2 with either Qg2# or 28. Qf1 Rxf1# to follow.
Another response that's worth looking at:
26. Qg1 Nxf2+
27. Qxf2 Qxd5+
C1) 28. Qf3 Qxf3+ 29. Kg1 Rxf4 30. Nxf4 Rxf4 31. Any legal move Qg2#
C2) 28. Kg1 Qxd2 shows a strong advantage as well.
And if white fails to respond to the threats, then the obvious approach is Nxf2+ followed by going after g2.
|Jan-05-17|| ||kevin86: The sharp queen sac leads to a quick win|
|Jan-05-17|| ||swclark25: I also preferred the 25)...Nxd3 and like <stst>'s (A) line.|
|Jan-05-17|| ||alphee: It's been a while since my last visit here but I got this one easily: 2 rook on an open column, a queen sac to remove the defender, it was too tempting.|
|Jan-05-17|| ||ChessHigherCat: Black must have been planning the Q sac at least since 23...d5, because otherwise it would be crazy to sac a pawn just to force white to pin the rook on f7.|
|Jan-05-17|| ||Kasparov Fan: i saw 25..Qxd5 26 Nxd5 Rxf2 then Nf3 to surround the king.
Nxd3 looks promising but positions after Bxf7+ looks ugly.|
|Jan-05-17|| ||dfcx: The obvious move for black is
Black has traded the queen for a bishop and rook, still threatening Rf1+.
White has several choices
A. 27.Ne3 Nf3 28.Qg1 (or Rxh2#) Nxg1 wins the queen back.
B. 27. Be3 Rf1+ 28.Qxf1 Rxf1+ 29.Rxf1 Bxf1
C.27. Qg1 Rxe2
|Jan-05-17|| ||NBZ: Presented as a puzzle, Qxd5 kind of jumps out: Nxd5 Rxf2 and for a small price in material, Black has the deadly threats of Nf3 or Bg2+. It's difficult to guard against both at the same time: if Nd4, Bg2+ wins the knight on d5. |
A little harder to foresee in advance that the ...d5 break works because of this queen sac.
|Jan-05-17|| ||Moszkowski012273: The real gem was 23...d5|
|Jan-05-17|| ||Pedro Fernandez: Hey <YouRang>, what the things are. Yesterday I saw 21...Bb4 and did stop my analysis, but this time I saw immediately the right move (and essentially the right variation too!). Why our mind is so strange my friend?|
|Jan-05-17|| ||Pedro Fernandez: My great friend <chrisowen>; I thought were you lost. Greetings.|
|Jan-05-17|| ||Pedro Fernandez: << kevin86>: The sharp queen sac leads to a quick win> And <Kevin>, take the queen is practically unique, since 26.Kg1, 26...Nf3+ is mortal!|
|Jan-05-17|| ||stst: < YetAnotherAmateur: <stst> I'm glad I wasn't the only one looking at 25. ... Nxd3>|
Yup, we're all kind of amateurs... and as such, esp. when time is tight, tend to have only special angles of view..
This 25,,,, Nxd3 is more subtle move, different in nature than the obvious QxP+ ready for a Q-sac. Sometimes, depending on the level, or circumstance, people may have particular slant towards some types of play....
It's almost time for another day's POD. Thanks
|Jan-07-17|| ||PavelPe: After 27.Bf3, white losses one piece, but the ending game is very complicated, because thera are 2B+2N against 1B+2N. One small mistake from black and it is draw.|
