|Apr-26-12|| ||newzild: Missed the main point!|
|Apr-26-12|| ||agb2002: White has a bishop and a pawn for a knight.
The pawn on e4 is weak. This suggests 31.Bxe4:
A) 31... Nxe4 32.f6+ Ke6 (32... Ke8 33.Qh8+ and mate next) 33.Qh3
A.1) 33... Rag8 34.Rxe4+ Kf5 35.Qf3+ wins material.
A.2) 33... Qf4 34.Rd4
A.2.a) 34... Kxf6 35.Rxe4 Qxe4 36.Rxe4 Rxe4 37.Qf3+ Ke5 38.Qxf7 + - [Q+2P vs 2R].
A.2.b) 34... Rag8 35.Rxe4+ Qxe4 36.Rxe4+ wins.
B) 31... Rxe4 32.Rxe4+ Nxe4 33.Qh4+ Nf6 34.Re1+ and 35.Qxf6 + - [2P].
|Apr-26-12|| ||Jamboree: Here's a beautiful continuation for the final position:|
It looks at first as if black has absolutely no way to stop mate next move. But if black could get his queen to c5, then he could interpose on f8 if white tries to mate with Qg8.
So, what black move temporarily prevents Qg8mate, while at the same time opens up c5 for the Black queen?
Remember that black is a rook up, so he can sac a rook and still be "in" the game. Thus, starting in the final position the answer is: 34. ... Rg4!
But that leads to this pretty conclusion:
34. ... Rg4! 35. Qxg4 Qc5 (preventing the g8 mate) 36. Qd7+ Kf8 37. Qd8+! Rxd8 38. Rxd8 mate!
Sweet! Black stops the back-rank mate on one side, so White sacs his queen and gets him on the other side!
|Apr-26-12|| ||sevenseaman: <jamboree> <34. ... Rg4! 35. Qxg4 Qc5 (preventing the g8 mate) 36. Qd7+ Kf8 37. Qd8+! Rxd8 38. Rxd8 mate!|
Sweet! Black stops the back-rank mate on one side, so White sacs his queen and gets him on the other side!>
A very interesting flight of fancy. Who gave it a half-penny that Vishy was on the verge of a mate.
Chess is the richer on a/c of this brand of 'out-of-the-box' thinking. Good, and entertainment to boot.
I gave the game a shot against Crafty. Today it submitted meekly but not before defending stoutly with 31...Rxe4 rather than 31...Nxe4 as in the game. Surprised, I was pushed into finding the ingenuity of 32. Qh4+ (early).( <Patzer2> has given this line a thought in the early kibitzing).
|Apr-26-12|| ||viking78: couldn't found a win today, every try led me to a draw|
|Apr-26-12|| ||LoveThatJoker: Very cool! A World Champion Anand puzzle!
<31. h3! Ng8>
[31...Rg2 32. Bxe4 (With the threat of 33. Bxg2+/Bxb7+ mating) 32...Rxb2+ (What else?) 33. Kxb2 Qb6+ (33...Qh2+ 34. Bc2+ mating) 34. Ka1 and White wins; 31...Rg3 32. Bxe4 Re3 33. Rxe3 Ng4 (33...Qe5 34. Bxb7 ) 34. hxg4 ; 31...Qe5 32. hxg4 ]

(33...Kf5 34. hxg4+ )
<34. Rd5+ Ke6 35. Rh5+ Kd6/...Kd7 36. Qd2+> 1-0 as White will pick up the R on g4 with or without a Queen swap on the d-file.
|Apr-26-12|| ||gofer: Black is just mounting a defense. If Pe4 gets taken then its all over.
So all White needs to do is clear Pe4 out the way. It has two defenders
so let's remove one.
<31 Bxe4! ...>
White threatens Bxb7+ winning "everything"...
<Hey! That's cheating! You can't remove a defender by taking the pawn
that's not removing the defender at all! That's a bloody <GOOT>!>
<I am not going to play if you cheat. I resign!>
1) The knight cannot re-take...
<31 ... Nxe4>
<32 Rxe4+! Rxe4>
<33 Qg5+! Ke8/Kf8>
<34 f6! ...>
Black's pieces are completely disjointed and cannot mount a defense!
2) The rook cannot re-take...
<31 ... Rxe4>

33 ... f6 34 Qh7+

So black must accept his fate! Death!
|Apr-26-12|| ||LoveThatJoker: Wow...OK! What an exciting position courtesy of Anand and P. Heine Nielsen (who I believe is his second, no)?|
I posted my answer and then saw that the game continuation differed. I then looked at other posts and saw that other kibitzers had also come up with 31. h3.
Then I was genuinely intrigued to see if I had found come by an alternate answer; so I clicked on the Crafty link provided by <sevenseaman> to see if I had missed anything.
It turns out that after 31. h3 Black has 31...Qf4 (31...Rf4 is also a move I missed for that matter), but then White has 32. Rxe4+ Nxe4 33. Qb6! - all of which I found in my first attempt. Crafty follows this up with 33...Re8, but after 34. Qxb7+ Kf8 35. Qb4+ (a critical move as 35. hxg4? Nxc3! when Black is better) 35...K moves 36. hxg4 and White's Queenside pawns will decide.
Is this as clear as Anand's combination? No. And did I miss 31...Qf4 and 31...Rf4 in my original post? Most definitely.
Therefore, as close as I came to finding an alternate solution today, I can pat myself on the back for the effort, but no points can be awared to my solution today.
|Apr-26-12|| ||sevenseaman: <LoveThatJoker> <31. h3 Ng8> would be a brave new solution, a very impressive line! Except that Black does not have to play 31...Ng8. He plays 31. Qf4 instead. (It was M>Hassan>'s line and I spent some time on it)|
The move puts a poser to White; if he takes the R with the P his Q goes, if he takes the Black Q the R escapes from the 'h' P by retaking with it.
I have tried very hard to resolve the dilemma but so far I am still searching for some light. See if you can find an answer.
|Apr-26-12|| ||gofer: <<jamboree> <34. ... Rg4! 35. Qxg4 Qc5>>|
How about going for the win without the queen sac. Isn't that even more

<36 ? >
White to force black to resign in two moves, as the only way to
avoid mate is to give up its queen!
|Apr-26-12|| ||sevenseaman: A very comprehensive view <gofer>. Black not taking the B with the N on the first move had intrigued me. Admittedly I had not considered this variation at all in my first solution. It took me some effort to find 33. Qh4+ in the line if Black responded 31...Rxe5.|
Damn good show. Indeed why I read your kibitzes regularly.
Your last move is a typo. It needed to be 37. Qxa8
|Apr-26-12|| ||whiteshark: I went for the shoddy <31.h3>. :(|
|Apr-26-12|| ||LoveThatJoker: <whiteshark> 31. h3 is not shoddy, man! It is entirely winning. |
The funny thing is that after 31. h3 Rf4, White is forced to go into the game continuation's tactical ideas in order to prove the win. :D
And after 31. h3 Qf4! 32. Rxe4! Nxe4 33. Qb6! White's extra pawns will decide in the endgame.
31. h3 is valid as an alternate solution but only if the poster finds all of these ideas - coupled with the ones that I brought to the fore.
|Apr-26-12|| ||chrisowen: Taking on e4 advantage in currently, bishop in effect sediment |
clearance in line rook takes night take bean up it down in dig fertile
31.bxe4 nxe4 32.rxe4 rxe4 and killer smooth 33.qg5+ in glorify it food
in for thought mating along back rank or dropping queen bin feed
approach 31.rxe4 also gets squeezed <32.rxe4+ nxe4 33.qh4+>.
|Apr-26-12|| ||asiduodiego: Beautiful combination!. I saw the first moves. The pawn on e4 seems doomed from the start. I saw 31 Bxe4! Nxe4? (it was preferable 31 ... Rxe4 32 Rxe4 Nxe4 33 Re1 and the Knight is gone anyway) 32 Rxe4 Rxe4 33 Qg5+ Ke8 And I thought "Well, after this, I can check and snatch the a8 Rook and I'm two pawns ahead, anyway". But I didn't saw the quiet move 34 f6!! And the mate is unavoidable in the next move. Brilliant!.|
|Apr-26-12|| ||mikmik777: White to play: 31.?
Anand vs P H Nielsen
(31. ...Rxe4 32.Rxe4 Nxe4 33.Qh4+ Nf6 34.Qb4+ Ke8 35.Re1+ Kd7 36.Re7+ skewering Black's queen)
(33. ...f6 34.Qg7+ wins Black queen again)
And, I think it's mate in two moves.
Time to check.
|Apr-26-12|| ||mikmik777: There was a slight deviation on move 33 but it's the same result..|
|Apr-26-12|| ||whiteshark: You've gotta <LTJ>! :D|
|Apr-26-12|| ||goldenbear: Easiest puzzle so far this week...|
|Apr-26-12|| ||Kruglov: <gofer> It seems that the best line of defense for Black is 31. Bxe4! Nxe4 32. Rxe4+ Rxe4 33. Qg5+ Ke8 34. f6! Rg4 35. Qxg4 Qc5 36. Qd7+ Kf8 37. Qd8+ Rxd8 38. Rxd8#|

<Crafty EGT> disagrees with you. <31 ... Nxe4> loses too quickly.
Have a play with the <Crafty EGT> link from <Sevensman>.
31. Bxe4! Nxe4

33. Qg5+ Ke8
34. f6! Rg4

Also, as I was hinting, I prefer rubbing salt into black's wounds, rather
than chucking in my queen.

|Apr-26-12|| ||CHESSTTCAMPS: In this middle-game attacking position, white has the black king virtually immobilized in the middle, protected only by a twice attacked e-pawn. The undeveloped Ra8 is another big problem for black. Clearly white *should* win and e4 is the focus of the position, but there are opportunities for white to go wrong. Initially I was interested in 31.h3(?) to try to displace the Rg4 from the defense of the e-pawn, but after 31... Qf4! black appears to be better. Eventually, a better idea I'd been looking at came together:|
Direct and correct. I knew the rook recapture was easy to beat, but at first I didn't see how to follow-up the knight recapture.
A) 31... Rxe4 32.Rxe4+ Nxe4 33.Qh4+ Nf6 34.Re1+ Kf8 35.Qh8+! Ng8 36.f6 and Qg7# follows.
A1) 33... f6 34.Qh7+ wins the Q
A2) 33... Kf8/e8 34.Qh8+ Ke7 35.Qxa8 and white is up exchange+pawn with black's king still hopelessly exposed.
A3) 34... Kd7 35.Qxf6 Qc5 (otherwise Re7+) 36.Qxf7+ Kc6 37.Re6+ wins.
B) 31... Nxe4 32.f6+! Ke6 (Ke8 33.Qh8+ Rg8 34.Qxg8#) 33.Qh3 decisively pins the Rg4 with Ne4 already pinned:
B1) 33... Rg8? 34.Rxe4+ Kf5 35.Qf3+ Rf4 36.Rd5+ wins.
B2) 33... Kf5 34.Rxe4 Kxe4 (Rg8 35.Qf3+) 35.Qxg4+ Ke3 (Ke5 36.Qg3+) 36.Re1+ Kd3 (Kf2 37.Qe2#) 37.Qe4+ Kd2 38.Qe2#
B3) 33... Kxf6 34.Qxg4 wins quickly.
B4) 33... Qf4 (best) 34.Rd4 Ke5 35,Qh5+ Kxf6 36.R4xe4 Qxe4 37.Rxe4 Rxe4 38.Qf3+ Ke5 39.Qxf7 looks like a winning ending (Q+2Ps for 2 disconnected rooks + doomed b7 pawn.
C) 33... Other 34.Bxb7+ (among others) wins.
Time for review....
|Apr-26-12|| ||kevin86: A beautiful combination by the future champ! I have to admit,I didn't see it coming...|
|Apr-26-12|| ||Jimfromprovidence: I found the alternative solution posted by <LTJ> much more intersting than the text, particularly the line |
31 h3 Qf4 32 Rxe4+ Nxe4 33 Qb6!
click for larger view
White threatens both 34 Qxb7+ and 34 hxg4 and black now cannot prevent the loss of one of his rooks.
