Sep-06-13  cocker: Far too hard for me. Somewhat relieved to see that no one else has solved it so far today. Surely this is saying something to <chessgames>?
Sep-06-13  Morttuus: Also,this is a mastery. A silent move breaking the chains and walls...I have tried several other moves,but I didnt got this one. BTW,this is an oldest Anands game I have ever seen. He was just 22 at this time!
Sep-06-13  Hongkonger: I got 29...d5 (it cried out to be played I thought) and the next couple of moves, but I certainly didn't see 32...Bg5 and the follow-up, I kept wanting to play Bb5+ but couldn't get it to work.

  bubuli55: First look with White K in the middle I'd like to open the center. So I got Black's next 3 moves.

29... d5 30. cxd5 Nxd5 31. exd5 Rxd5

Missed that 32... Bg5!

I had 32... Bb4+

With White up a piece at that point, I was afraid White's next move would be 33. Rxc6 returning the piece and shutting down Black's threats.

I know! 32...Bg5 33. Rxc6 Rxd2+ 34. Kf1 Qf2# I know!

Friday miss :)

Sep-06-13  mistreaver: Friday. Black to play. Difficult. 29?
White's position is difficult. His pieces are all boxed together and he has no space I am almost certain that the blow must be on the e4 or d5 squares. But there are lot of options. Which one is correct? I am gonny try the knight sacrifice first:
29 ... Nxe4
30 Nxe4 (no real choice here)
30 ... d5
I suppose this could be it maybe.
A) 31 cxd5 Rxd5
32 Qe3 Rd4 and
33... Bg5 and white is kinda tied up.
B) 31 cxd5 Rxd5
32 Qf3 Rd4 and the queen is pinned
C) 31 Nd2 cxd4
32 Qxd4 Rd4
and white will get slowly suffocated i think.
I am gonna stop and check it here since it is impossible for me to calculate every line and i would probably just rely on my intuition here.
-----------------
Ah, my intuition has failed me. The point is that in my A variation : 31 cxd5 Rxd5
32 Qe3 Rd4
33 Nac5!!
white has this move which preserves advantage.
And in every other line, instead of Rd4,
Bb5+ is devilishly strong move, say
31 cxd5 Rxd5
32 Qf3 Bb5+
33 Qd3 (forced)
33... Bxd3
or 31 cxd5 Rxd5
32 Qb3 Bb5+
33 Kf3 Rd3+
Unfortunatelly, due to the first variation, i can only go 29 ... Nxe4
30 Nxe4 Qd7
31 b3 Qxf5
when there is everything to play for.
29... d5! is much more pretty and efficient, and it's a shame that i missed it's significance

  agb2002: Black has the bishop pair for a bishop and a knight.

Black has a number of options, 29... Qd7, 29... Qb7, 29... Ng4, 29... Nh5, 29... d5, etc.

The latter tries to exploit White's clogged development:

A) 30.cxd5 Nxd5

A.1) 31.exd5 Rxd5

A.1.a) 32.Rxc6 Rxd3 33.Rc8+ (33.Kxd3 Rxc6 - +; 33.Rxa6 Qxa6 - +) 33... Kh7 34.Kxd3 Qd7+ and 35... Qxc8 - +.

A.1.b) 32.Qb3 Bg5 33.Rc2 Qd7 34.Nc5 Rxd2+ 35.Kf1 Qxf5+ 36.Bf3 (36.Kg1 Qf2+ 37.Kh1 Qxg2#) 36... Rxc2 37.Nxa6 e4 looks winning.

A.1.c) 32.Qe3 Qxe3+ 33.Kxe3 Bg5+ and 34... Bxd2 - +.

A.1.d) 32.Qf3 Rxd2+ 33.Kxd2 Bxf3 - +.

A.1.e) 32.Qg(h)3 Bg5 33.Nb3 (33.Rc2 Bxa4; 33.Nc5 Rxd2+) 33... Bxa4 with the threats Bxc1 and Bxb3 followed by Rd2+.

A.2) 31.Kf1 Nf4 withe the threats N(R)xd3 and Bxg2+.

A.3) 31.Qb(g)3 Nf4+ and 32... Rxd2 - +.

B) 30.exd5 Nxd5 looks similar to A.

C) 30.Kf1 dxe4 looks very bad for White.

Sep-06-13  MarkFinan: My minds switched off right now, but i was looking at 29...Ng5 threatening a mate with the queen on f2, but as there are so many pieces on the board and ive just caught a case of chess block, I cheated and saw d5, with i guess some attempt to pin the queen and king with the LSB. Think il just go through the game later lol :-)
Sep-06-13  gars: I did not solve it, from Wednesday on everything is too hard for me. Anyway, what is the threat after 34) Rxd2? Can anyone help me? Tanks a lot.

  bubuli55:

< gars > after 34. Rxd2

34... Bb5+ 35. Kf3 Rxd2 threatening ... Rd3+ attacking K & Q. Or ... Qf2+ with mating threats.

If 36. Bd2 ... Rac6 keeping the pressure.

Hope that helps. :)

Sep-06-13  MarkFinan: Yeh, just had a good old deek and Bb5+ is crippling for white.

  kevin86: the exchanges and breakthrough by the rook win this one.

  Jimfromprovidence: I got 29...d5 30 Qe3!? Qxe3+ 31 Kxg3 Nxe4 32 Nxe4 dxe4.

The threats are 33...Bg5+ winning the rook or exchange. Depending where the king moves perhaps 34...e3 or 34...Rd2 comes next.

Note that white cannot play Rc2 because that leaves his knight unguarded.

  perfidious: The winning idea readily suggests itself to an experienced Sicilian player, after which it is matter of making the tactics work.

  patzer2: The brilliant 29...d5!! initiates a combination to trade the Knight and a pawn for two central White pawns, which exposes White's King and Queen to a winning attack.

However White's position can be decisively exploited with other less brilliant alternatives. For example, <Gofer> <MarkFinan> and <morfishine>'s suggestion of 29...Ng4! is also sufficient. For example after 29...Ng4! 30. Qg3 h5 31 h3? (position below),

the deflection 31...Bh4! (position below) is crushing.

Here 32. Qxh4? (Others such as 32. Qf3 Nh2! also lose) yields the following position

with mate-in-two after 32...Qe3+ 33. Kf1 Nh2#.

Sep-06-13  MiCrooks: While d5 is beautiful shoving the pawn right into c4 and e4, Ng4 is still completely winning and only slightly "worse" than the game continuation.

I think it is funny that all of those that "found" d5 but missed Bg5(!) also missed that the immediate Rxd2!! instead of Bg5 is by far the best move on the board!

I don't fault Chucky for not finding it, as Bg5 is quite concrete and pragmatic. But how much nicer if he had seen and uncorked Rxd2 instead...

Sep-06-13  MiCrooks: You also have to allow for the fact that Anand did not put up the best defense, so Chucky having spent much time I am sure looking through d5 would have been searching for clear, concrete wins as Anand varied from the best defense.
Sep-06-13  patcheck: Material is equal.

This puzzle has really been very difficult for me. I think the solution could be: Nxd5 or d5 but I didn't get the solution.

Sep-06-13  morfishine: <patzer2> Thanks for looking! Yes, the deflection <Bh4> is what I had in mind, but at a different move: 29...Ng4 30.Qg3 <30...Bh4>. Your continuation is more decisive

*****

Sep-06-13  gars: <bubuli55>, Thanks a lot!
Sep-06-13  waustad: I started it right. Anand didn't walk into the tactical stuff I noticed, but there was more than I realized.
Sep-07-13  DcGentle: Well, it's a pity but understandable that players don't want to suffer until checkmate, once their play has become hopeless. Nevertheless some beautiful twists and turns are missing from the games this way.

The process of checkmating can be tactical when removing the enemy king's defenders, but the positional element of restricting the enemy king dominates.

So this is not boring and here there are some mate lines:

[Event "Linares, Vaiants not played"]
[Site "Linares"]
[Date "1991.??.??"]
[Round "8"]
[White "Viswanathan Anand"]
[Black "Vassily Ivanchuk"]
[Result "0-1"]
[ECO "B90"]
[Annotator "Gentle,DC"]
[SetUp "1"]
[FEN "6k1/q3bpp1/r1b4p/p2rpP2/Np6/1Q6/PP1NK1PP/2RBR3 b - - 0 32"]

32... Bg5 {<was played, but...>}

(32... Rxd2+ {<is an even more spectacular route to checkmate. Black's position is so strong, that the removal of knight d2 will speed up the end, even by giving the quality.>} 33. Kxd2 Qf2+ 34. Be2 Be4 {<threatening 35... Bg5+ and 35... Rd6+ with mate in 5 respectively.>} 35. Rc8+ Kh7 36. Qd3 Bg5+ 37. Kc2 Bxd3+ 38. Kxd3 Qxe1 {<Obviously the white king is in a mate net.>} 39. Bh5 e4+ 40. Kc4 Qf1+ 41. Kb3 Qd3+ 42. Rc3 bxc3 43. bxc3 Qb5+ 44. Kc2 Qxa4+ 45. Kb2 Rb6+ 46. Ka1 Bf6 47. Bg6+ Kh8 48. Bxf7 Qd1#)

33. Rc2 Bxd2 {<Black resigned, but let's see the real finish.>}

(33... Bxd2 {<Now interposing a piece at c5 seems to be the strongest defense.>} 34. Nc5

(34. Rc5 Bxe1 {<By taking the rook now White is kept off from taking rook d5 due to fast mate.>} 35. Qe3 Bd2 36. Qf2 Rd4 {<threatening 37... Bf4 and 37... Bxa4.>} 37. Kf1 Bxa4 {<All of a sudden rook c5 and bishop d1 are loose pieces.>} 38. Rxe5 Bxd1 39. Re8+ Kh7 40. g3 Rc6 {<threatening 41... Rc1 with mate in 7.>} 41. Kg2 Rc2 42. Rc8 Qb7+ 43. Kg1 Rxc8 44. h4 Bg4 45. Kh2 Rc1 46. Qg2 Re4 47. Qf1 Re2+ 48. Qxe2 Qh1#)

34... Bb5+ 35. Kf3 {<Black could capture rook e1 now, but restricting the white king by optimizing the positions of Black's heavy pieces is more important here. Engines don't get this.>} Rad6 36. Rxd2 Rxd2 {<with the threat 37... Qxc5 and fast mate.>} 37. Rxe5 Qa8+ {<The queen will head to d8.>} 38. Ne4 Rxd1 39. Kf4 Qd8 {<with the main threat 40... Qh4+ and mate in 6.>} 40. Qg3 R6d3 41.
