|Oct-13-08|| ||sleepyirv: Took a bit longer than normal as I looked for a mate. But hey, forks are fun!|
|Oct-13-08|| ||ed gantro: Hi guys, I missed the last difficult, does anybody remember the game?|
|Oct-13-08|| ||lost in space: there are at least 2 solutions:
26. Qxe8+ Qxe8 27. Nf6+ Kh8 (foreced) 28. Nxe8
26. Nf6+ Qxf6
no good is 26...Kh8 27. Qh4 Re4 28. f4 and the mate to follow (Bf8)
27. Qxe8+ Kh7 28. Bf8 and White is up a minor piece
|Oct-13-08|| ||dzechiel: White to play (26?). White has two minor pieces for a rook. "Very Easy."|
There looks to be more that produces a "winning" position here, but some of them allow black to put up more resistance than others.
The more I look at it, the key move must be
I had also considered 26 Nf6+, but this is much more forcing and leaves white two pieces up.
26...Qxe8 27 Nf6+ Kh8 28 Nxe8
Black can play 28...Rxa3 and see what he can managed with the passed a- and b-pawns, but it's more likely that he just resigned.
Time to check.
|Oct-13-08|| ||Puffen: Why didn't black play Nxg3 on move 20. ?|
|Oct-13-08|| ||DarthStapler: Easy got it|
|Oct-13-08|| ||MiCrooks: Game was Serper Barsov 1988
Came up with a winning line here, but not the best one. My first thought was that it was too hard for a Monday, but rather than looking a second longer I just came out to look.
I went with Nf6 right away which wins a whole piece, but the other line wins two! With mine the Queens stay on which in this case I liked, but really the other was instant resignation whereas in mine you could take the a-pawn and try to survive long enough to make something out of your passed pawn.
|Oct-13-08|| ||zb2cr: Substitute the Black Queen for the Rook on e8! 25. Qxe8+, Qxe8; 26. Nf6+, Kh8; 27. Nxe8 leaves White 2 full pieces up.|
|Oct-13-08|| ||stacase: Less than a minute to figure out that delaying the Nf6+ fork a move with Qe8+ wins the Rook and trades Queens. |
Forcing trades once you're up material is my favorite tactic.
|Oct-13-08|| ||zooter: 26.Qxe8+ Qxe8 27.Nf6+ followed by Ne8 scoops up white|
The other continuation could be:
26.Nf6+ Qxf6 27.Rxe8+ Kh7 28.Bc1
In the first line, the queens are gone and its R+N vs. R
In the second line, the queens are there and its Q+R+B vs. Q+R
Guess its personal choice though i'd prefer to exchange off queens
|Oct-13-08|| ||MostlyAverageJoe: <lost in space: there are at least 2 solutions:>|
There is also a third one: 26.Qf4, threatening a fairly quick mate (Nf6 Kh8 Bf8 with Qh6# to follow). The line goes something like:
26. Qf4 Re6 27. Bg5 Qc7 28. Nf6+ Rxf6 29. Qxf6
and white ends up also a piece ahead.
|Oct-13-08|| ||abstraction: <Puffen: Why didn't black play Nxg3 on move 20. ?> 21. fxg3 gives white immense advantage with the open f-file against the now weakened King position, eg., three pieces now bear down on f7 (and note 21. ... gxh6? leads to a mate in four beginning with 22. Rxf7.)|
|Oct-13-08|| ||TheaN: 1/1
Mate seems plausible, and I actually thought that 26.Nf6 combined with Qh4 would go there, but 26.Nf6 Qxf6 leaves White stumped with a piece up but Queens OTB.
White: a3, d4, f2, g2, h2, Ng4, Bh6, Rf1, Qe4, Kg1
Black: a7, b5, d5, f7, g6, Rc3, Re8, Qd8, Kg8
Material: + vs
Candidates: Nf6, <[Qxe8]>
<26.Qxe8> and a fork is forced here, as Black cannot decline this sacrifice effectively.
<26....Kh7 27.Qxd8 Rc1 28.Qf8 Rxf1 29.Kxf1 f5 30.Qg7 1-0>
<26....Qxe8 27.Nf6 Kh8 28.Nxe8 > and White, instead of playing N+B+R vs R+R suddenly plays N+B+R vs R. More than enough, I guess, even after Rxa3.
|Oct-13-08|| ||chrisowen: Isnt it great saccing the queen. Re8 looks like the mistake allowing Rg3 and kingside play!|
|Oct-13-08|| ||outplayer: I think that black could play 20...Nxg3.|
|Oct-13-08|| ||ThePawnOTron2: This was really a "very easy" puzzle, indeed! 26.Qxe8+ [decoys the queen to e8, removes defender of f6-square] for a knight fork at f6.|
|Oct-13-08|| ||ThePawnOTron2: ed gantro, the last difficult was Gelfand vs Salov, 1996 25.?|
|Oct-13-08|| ||agb2002: Too many holes around the black king.
A) 26.Nf6+ Qxf6 27.Qxe8+ Kh7 28.Be3 Rxa3 29.Qxb4 and black does not have any compensation for the bishop.
Ignoring DAUT (Dont Analyse Unnecessary Tactics):
B) 26.Qxe8+ Qxe8 27.Nf6+ Kh8 28.Nxe8 Rxa3 29.Nf6 Ra6 (otherwise Rc1 or Re1 threatening mate) 30.Nxd5 and black ends up worse than in line A).
Id go for line B). Time to post, check and complete my Saturday & Sunday analyses (if my family allows me...).
|Oct-13-08|| ||Patriot: Two candidates immediately stood out: 26.Qxe8+ and 26.Nf6+.|
26.Qxe8+ clearly seemed better because it wins a piece for nothing.
26.Nf6+ only wins the exchange. This is true regardless of what is remaining on the board. This also leaves black with the queen and a better chance for counterplay. So this line can be ruled out early as the best move.
|Oct-13-08|| ||OhioChessFan: Hard to believe Black bothered to play his 26th move.|
|Oct-13-08|| ||5hrsolver: At first I was a little puzzled by how the white queen gets attacked by a pawn and a rook at the same time.|
|Oct-13-08|| ||Oliveira: Why "Hastings 3940"?|
|Oct-13-08|| ||cydmd: The combination actually started on move 25.Bxd5. Black is also lost if takes the bishop with the queen.|
25... Qxd5 26.Nf6+ taking the black queen.
|Oct-13-08|| ||YetAnotherAmateur: The solution is blindingly obvious as soon as you look at the position, for 2 reasons:
1. The d5 pawn means that either the queen has to move, white plays Nf6+, or white loses his queen without compensation.
2. The black queen is preventing Nf6+, which white would love to be able to play because it forks the king and e8.|
So the obvious thing to do is divert the black queen away from guarding f6, while at the same time moving the white queen. Ergo 26. Qxe8. The same puzzle a move earlier would probably have been a lot more challenging.
|Oct-13-08|| ||kevin86: Over t5he board,it is not the easiest of positions. The natural move would be a retreat of the queen to b1 or over to f4. Being that this IS a Monday puzzle,it becomes second nature to look for a quick,sharp move as Qxe8+ is.|
I like to call a combination as this as a "loan at shark rates".
