|Mar-29-10|| ||hulkweazel: Gawain, just for clarification the knight fork does not win a piece because black will retake with his bishop. It does clear the board however, with white already with a slight material advantage.|
|Mar-29-10|| ||al wazir: If Smyslov wanted to simplify, why didn't he just play 26. Nxe6+ ? |
There follows 26...Rxe6 (26...Nxe6 27. Qf5+) 27. Rxe6 Qxh2+ 28. Kf1 Nxe6 29. Qxe6 Qh1+ 30. Ke2 Qxa1 31. Qc8+ Kg7 32. Qxc7+.
|Mar-29-10|| ||ChocolateCakeLover: Woke up very late...(still sleepy)...
Took me a minute or two to find Qxg7 mainly because I was looking for a mate.
<CG.com> that would be nice.
|Mar-29-10|| ||TheaN: Monday 29 March 2010
Material: White up, +2 /
Candidates: Qxe8†... <[Qxg7†]>
White is clearly up in material but Black has some dangerous counterattacks. In order to par these, White may be willing to simply. In fact, he can just win a piece and go a Rook up. It took me a while to find because I was looking for mate, but White wins with:
<28.Qxg7†! Kxg7 29.Nh5† Kf6 30.Nxf4 > and White may simplify easily. Time to check.
|Mar-29-10|| ||Once: Smyslov sets up this simple little combination with a couple of nifty knight checks. Let's rewind to the position after black has played 25... Qf4:|

Smyslov is the exchange up, so all he needs to do is to swap pieces into an easy endgame. But ideally he has to do this without allowing black to play Qxh2+ or Qxg4+.
Smyslov spots that the black Ng7 and Qf4 are a knight fork apart with a safe fork square on h5. So if knights could move sideways, he would be able to play 26. Qxg7+ Kxg7 27. Ng5-h5+.
With a little bit of chess magic, he repositions his knight to f6 so that the combination works:
26. Nh7+ Kg8 (26.... Ke7? 27. Qxg7+ threatening either Qf6+ or Qe5+ to force the exchange of queens).
27. Nf6+ Kf8 (27...Kh8 28. Kh7#)

And there we have it ... the stage is set for the finale.
|Mar-29-10|| ||agb2002: White has a rook, a bishop and two pawns for the bishop pair.|
Black threatens 28... Qxh2+ 29.Kf1 Qh3+ 30.Ke2 (30.Kg1 Bh2+ 31.Kh1 Bg3+ 32.Kg1 Qh2+ 33.Kf1 Qxf2#) Bxg4+ 31.Kd2 Bf4+ 32.Re3 Bxe3+ 33.Kd3 (33.fxe3 Qxe3#; 33.Kd(e)1 Qh1#) Bc1+ 34.f3 Re3#.
The white knight is very close to Black's royal family. This suggests 28.Qxg7+ Kxg7 29.Nh5+ Kf7 (to keep protected both the rook and the bishop) 30.Nxf4 Bxf4 31.Re2 (31.f(h)3 Bd2 and 32... Bxc3) Rg8 (31... Bxg4 32.Bg6+) 32.f3 followed by Rae1 and the invasion of the white rooks or a liquidation of pieces, leading to a won endgame.
I've considered other moves like 28.Nd7+ or 28.Nh7+ but were unable to make them work.
This should be Smyslov's week, imho.
|Mar-29-10|| ||agb2002: <Jimfromprovidence: I got <dzechiel>'s line except at the end, where I see the piece swapping continue with 31 Bf5.>|
I saw 31.Bf5 but preferred 31.Re2 to avoid 31... Bd2, but it probably doesn't make a big difference.
|Mar-29-10|| ||Hovik2009: Queen takes the black knight with a check, and everything seems gloomy for black!|
|Mar-29-10|| ||gofer: This was more difficult than yesterday's! Lots of options for white, bit none of them seem to make a huge
material advantage that we expect on a Monday. So perhaps we just swap off into an end game where we are
a Rook v Bishop up and 3 connected passed pawns up... ...er that sounds really quite good on second
28 Qxg7+ Kxg7
29 Nh5+ Kf7
30 Nxf4 Bxf4
Now what? Black is about to play Bd2 which we cannot allow and also Pg4 is threatened. So what is the
the cleanest way to defend these??? This is where my play is lacking clarity!!! I have had a look at
this OTB and I think I would play...
31 h3 Bd2
32 Re3 Bxe3
33 fxe3 ...
So effectively giving up the rook v bishop advantage, but swapping into a position where white has
two connected passed pawns and a much more active position!
Time to check...
|Mar-29-10|| ||GaeBulg: I did see the continuation 28. Qxg7+ Kxg7 29. Nh5+ forking the Queen...but I saw that white won no material for that play and merely traded off material. This made me think that this continuation was wrong and that there was a superior one. I couldn't find any, so I gave up lol.|
|Mar-29-10|| ||eblunt: I had the right idea - simplify, but did it by 28. xg7+ xg7 29. xe8+ f7 30 xc7 xc7 giving white 2 + 2 + against +. Not as good as others have given, but still winning comfortably IMO.|
|Mar-29-10|| ||wordfunph: 28.Qxg7+
28...Kxg7 29.Nh5+ forking the Queen
easy indeed but wait til Friday and i could not find the solution. :-)
|Mar-29-10|| ||agb2002: <eblunt: I had the right idea - simplify, but did it by 28.Qxg7+ Kxg7 29.Nxe8+ Kf7 30.Nxc7 Qxc7 giving white 2 + 2 + against +. Not as good as others have given, but still winning comfortably IMO.>|
Black can play 30... Qxg4+ 31.Kf1 (31.Kh1 Qf3+ 32.Kg1 Bh3 - +) Qh3+ 32.Ke2 (32.Kg1 Qg4+ repeats moves; 32... Bg4 is interesting: 33.f3 -33.Bd3 Bf3 34.Bf1 Qg4+ 35.Bg2 Qxg2#- Bxf3 34.Kf2 Qg2+ 35.Ke3 Qxc2 36.Kxf3 Qxc3+ and 37... Qxd4) Bg4+ 33.Kd2 (33.f3 Qxf3+ 34.Kd2 Qf2+ 35.Kd3 Bf5+ 36.Re4 Bxe4#) Qxh2 with the double threat Qxf2+ and Qxc7.
|Mar-29-10|| ||JohnBoy: I like these "how to efficiently win a won game" puzzles.|
|Mar-29-10|| ||patzer2: Smyslov's 28. Qxg7+ ends the game with a Queen sham sacrifice to set up a winning Knight fork.|
|Mar-29-10|| ||eblunt: <agb2002: > Yes, agreed, I missed that. Thanks, that makes me 0/1 for the week.|
|Mar-29-10|| ||johnlspouge: Monday (Very Easy)
Smyslov vs Lutikov, 1960 (28.?)
White to play and win.
Material: R+2P for B. The Black Kf8 has 1 legal move, e7, which Re1 x-rays. Black threatens mate:
28…Qxh2+ 29.Kf1 Qh3+ 30.Ke2
[Kg1 Bh2+ 31.Kh1 Bg3+ 32.Kg1 Qh2+ 33.Kf1 Qxf2#]
30…Bxg4++ 31.Kd2 Bf4+ 32.Re3 Bxe3+ 33.Kd3 [fxe3 Qxf3#]
33…Bc1+ 34.f3 Qxf3#
White therefore seeks a simplification to his won endgame.
Candidates (28.): Qxg7+
28.Qxg7+ Kxg7 29.Nh5+ K any 30.Nxf4 Bxf4
White still has R+2P for B, but Black has lost his mate threat and should lose.
I know we asked for harder puzzles, but c’mon, this is Monday!
|Mar-29-10|| ||JG27Pyth: Got it, after some work and entirely without confidence that I wasn't missing some quick kill. Hardest Monday ever, but a good puzzle I think.|
|Mar-29-10|| ||vsadek: Rest in peace dear Grandmaster.
Poèivao u miru dragi velemajstore.
|Mar-29-10|| ||turbo231: |
I was disappointed at first I thought what good is this. A queen and knight exchange, then I noticed the 3 passed pawns, the massive material advantage. The queen and king fork was easy to see and as good as it gets. The only hard part about this puzzle was trying to find something better, which their isn't any. On second reflection this puzzle was kinda easy.
|Mar-29-10|| ||mig55: After Nxf4 and Bxf4, white must play Re2 to protect the field d2 for the black B....|
|Mar-29-10|| ||micartouse: My thought process with this puzzle was approximately like everyone else's. It took a minute and went like this:|
1. Saw Qxg7+ instantly.
2. Realize that it doesn't gain material.
3. Look briefly for a different forcing sequence and can't find one.
4. Suspicious it's a spoiler (except for seeing the name of the player with the White pieces).
5. Count material and realize White has a crushing endgame, and a queen trade would avert countertactics.
6. Qxg7+ it is.
Ordinarily 5 is my first step in puzzles; I always count material first. But I have a bad habit of bypassing this step on Mondays since I expect a neck snapping victory. I liked this puzzle.
|Mar-29-10|| ||newzild: This took me longer than Sunday's puzzle!|
|Mar-29-10|| ||chrisowen: These days 3.Nd4 enterring the spanish bird is not common. Can a rye gentleman like black hope it will unsettle Vasily in digging up an old sideline? Looks like Qh6 is landing the hammer blow, mind you I had a gas seeing whether Re3 would work, I think it might. Watch out the queen fork Qg7+ Kxg7 Nh5+ Kf7 Nxf4 call you tick off.|
|Mar-29-10|| ||agb2002: <johnlspouge: Monday (Very Easy) ...

Hardest Monday ever, but a good puzzle I think.>
Aug 17, Monday: Portisch vs Korchnoi, 1988 was much harder. I like CG's unpredictability :)
