  Penguincw: < Ultra: No solve for me. >

Me neither. I didn't see any possible sacrifices, so just played a move like 38...Rb3. I did see white's threat of a7, Rg8+, a8=Q+.

Great job by black for pulling off the win. I saw the Q vs. RN ending, and thought black would be lucky to put together a fortress...

For those who want a perhaps easier puzzle, try this one:

This position would've occurred in Anand vs Carlsen, 2010 if black played 67...Rd8 instead of 67...Re8. Find the best move.

Mar-06-16  ndg2: I saw white's threat of queening via rook sac on g8 and I saw even black's first move c3 but was under the impression that this could only a fortess at most for black.

Since the result is 0:1, white surely must have blundered somewhere?!

But no, black's win is actually forced. White can prevebt mate only by going into a lost endgame.

So, 0.2 points for me and kudos for the black player to see all that OTB.

Mar-06-16  M.Hassan: Black to play 38...?
Black is a pawn up
Black rook loves to occupy the a file but the knight on c3 prevents it so, Block pushes a pawn to displace the knight: 38..............d4
White is willing to sac the Knight:
39.a7 dxc3
40.Rg8+ Kxg8
41.a8=Q+ Kg7
Now Black has Rook+Knight+5pawns including an advanced pawn on c3 against White's Queen+3pawns. I did not go through the rest of the game as it likely is lengthy but can only predict that White has a very difficult job to win this game if at all he wins which he has not since the result is 0-1
Mar-06-16  diagonalley: what a fabulous endgame!... well out of <diagonalley>'s league :-(
Mar-06-16  JimmyRockHound: Great stuff. After looking at it with an engine there was only one move for Black pretty much all the way.
Mar-06-16  morfishine: I was barsking up the wrong tree
Mar-06-16  Cheapo by the Dozen: I got the first move pretty easily. :)

But I didn't have any particular plan after the response Ne4. So I quit on the problem pretty soon after that.

Mar-06-16  gofer: I look at this and I see...

<38 ... d4>

I don't think black can play the following...

39 a7 dxc3
40 Rg8+ Kxg8
41 a8=Q+ Kg7

click for larger view

...because black has a lot of tricks up its sleeve, starting with

42 ... Rb1+
43 Kg7 Ne1+
44 Kf1/Kh3 which point black may be able to play b2 or Nf3

I suspect that white might play...

<39 Nd4 ...>

But beyond that I am lost...


Hmmm, okay white took the bait and came off worst, but only because black had seen the possibilities of <45 h5!>

...and this leads to a forced win 5 moves later...

click for larger view a 12 move combination in all...

This is really way beyond my level...

Mar-06-16  dfcx: Black has an extra pawn but white's pawn is closer to promotion. Black cant prevent promotion but can get returns with the only move,

Now if white forces to promote,
39. a7 dxc3 40.Rg8+ Kxg8 41.a8=Q+ Kg7

Black should win with R+N+P against queen, only needs to guard against perps.

So the trickier continuation is when white plays something like 39.Ne4 aiming for a draw. Now black maintains its extra pawn advantage but needs to defend against the white pawn promotion.

OK I see white accepted the challenge. But I did not see moves 45...h5 and 46...e5. Amazing sequence.

Mar-06-16  jith1207: That's insane - Not sure if he had calculated till the end or till all the major pieces go off and still the end game was another juicy puzzle. Perfect for the Sunday.
Mar-06-16  Patriot: White's pawn is faster so black needs to get his rolling.

38...d4 39.Ne2 Rb1+ 40.Kg2 Ne1+ 41.Kf1 d3

a)42.Ng1 Nf3+ 43.Kg2 Rxg1+ 44.Kxf3 d2
b)42.Nc3 Rc1 looks winning.

There's no way the entire game line was calculated through.

Mar-06-16  wooden nickel: After not getting much out of 38... d4 39.Ne4, I started liking 38... Rb3 If 39.Ne2 g4 40.a7 Rb1+ 41.Kg2 Ne1+ 42.Kf1 Nf3+ 43.Kg2 Ra1 44.Rb8 looks good

  agb2002: Black is one pawn ahead.

White threatens a7, Rg8+ and a8=Q.

I think I'd play 38... d4 and if 39.a7 then 39... dxc3 40.Rg8+ Kxg8 41.a8=Q+ Kg7 42.Qa1 Rb2 looks winning for Black.

Or 39.Ne2 Rb1+ 40.Kg2 Ne1+ followed by 41... d3 looks good for Black.

However, I'm not sure what to do in the case of 39.Ne4.

Mar-06-16  BOSTER: But if white played 38. a7 ( not Nc3 ) sacr the knight, he'd queening with black pawn on d5.
Mar-06-16  Patriot: <BOSTER> 38.a7 is good! 38...Rxb5 39.Rb8 Ra5 40.a8=Q Rxa8 41.Rxa8 =.

39.Rg8+ Kxg8 40.a8=Q+ leaves black ahead materially.

  patzer2: Picked the game move 38...d4! for my Sunday puzzle solution and got as far as visualizing the game sequence through 39 a7 dxc3 (39...Kf6?? 40. Rg8! ) 40 Rg8+ Kxg8 41 a8=Q+ Kg7 .

However, I didn't have a clue as to whether it was winning for Black or not. I wonder if Black saw it all the way through, or was just playing a tough position on solid instinct. Either way, it's a very impressive combination.

According to the computers, after 38...d4! Black maximizes resistance with 39. Ne4 when strong play might continue 39...Rb1+ 40. Kg2 Ne1+ 41. Kh3 h6 42. Nd2 Rb2 43. a7 Ra2 44. Nb3 h5 45. Nxd4 g4+ 46. Kh4 Ra5 47. Nb5 Nf3+ 48. Kxh5 Rxb5+ 49. Kxg4 Ne5+ 50. Kh4 Rb4+ 51. f4 Ra4 52. h3 Nc6 (-2.31 @ 25 depth, Deep Fritz 15).

Black's game takes a turn for the worse with 38. Nc3? (-1.36 @ 26 depth, Stockfish 6). Instead, 38. a7 = (0.00 @ 21 depth, Komodo 8) seems to hold for White.

Mar-06-16  King Harvest: Ah Sunday, the humbling.
Mar-06-16  stst: For defense, N goes back c5
For attack, d4 to drive and arrest the White N

Guess for a POD, attack is more preferred,
see how it goes!
