May-19-07  hitman84: Could someone explain as to why top players repeat moves in classical time controls even when the winning line is obvious ? I personally feel it shows disrespect to the opponent.

  virginmind: <hitman84> well, the repetition between moves 37-40 i suppose was done to quickly reach the time check - both players were very low on time.

as of that from moves 45-48 hm...i dont know, maybe nisi was hoping/checking from a different reply of adams which would had brought up a more interesting win.

  Eyal: Instead of 42...h6? Adams should have played h5. If 44...Bxg5, 45.Nf6+ Bxf6 46.Rxg6+ Bg7 47.Ne7+ wins for White.

  Eyal: In a way, Adams' troubles began as early as 13...Nb6, leaving his kingside relatively exposed - 13...Nf8, as played in Bologan vs Romanishin, 2005, is safer.
May-19-07  russep: What happens if Adams goes 53...Kf8?

  Eyal: <russep: What happens if Adams goes 53...Kf8?> 54.Rf5
May-23-07  Fey: Why did Nisipeanu repeat moves in this game? Just take a look at the other Adams - Nisipeanu game in the Mtel Masters 07 tournament. Adams had a crushing position and humiliated Nisipeanu by repeating moves a couple of times. The GMs commenting on ICC said it was torture.. I guess it was revenge.

  Sneaky: Players repeat moves to put more time on the clock. Just in case he needed more time to work out the win, he'd get to the 60th move quicker.

Of course, a draw was never part of the plan.

  An Englishman: Good Evening: So yours truly flubbed Saturday, Friday, Thursday and Tuesday (??) this week, but not only solved Sunday, I found the main line as played in the game.

And I never even played the Ruy Lopez.

Jun-14-15  diagonalley: my guess is that the moves were repeated because white wasn't sure how best to continue from that point ... nonetheless, an excellent attack... though perhaps 'insane' is not quite the apt label
Jun-14-15  paramount: Instead of being patchy, you might as well make a puzzle 2 moves earlier at 41???

41.Nf5!!

I dont know if the friction might as well increase the difficulty because i think 41?? is easier that 43??

Right...?

Jun-14-15  wooden nickel: Apparently on Black's kingside "da spielt die Musik" i.e. "that's where the music is playing" whereas the Nf5 is hanging. 43.Ng4! brings more material into the picture and if 43... gxNf5 then 44.Nf6+ Kh8 45.Nxd7

  agb2002: The material is identical.

Black can take the knight on f5.

The queen sac 43.gxh6 Bxh4 44.Rxg6+ doesn't seem to work.

A more interesting option is 43.Ng4, increasing the pressure on h6 and also aiming at the defenseless bishop on d7:

A) 43... gxf5 44.Nf6+

A.1) 44... Bxf6 45.gxf6+ with the idea Rg7 and Bxh6 looks good for White.

A.2) 44... Kh8 46.Nxd7 Qd8 47.exf5 Qxd7 48.f6 followed by g6 looks winning.

B) 43... Bxg5 44.Bxg5 gxf5 (44... hxg5 45.Nf6#) 45.Nxh6+ wins (45... Nxh6 46.Bxh6+; 45... Kh7(8) 46.Nxf7+; 45... Kg7 46.Bf6+ Kh7(8) 47.Nxf7+).

C) 43... hxg5 44.Bxg5

C.1) 44... Bxg5 45.Nf6+ Bxf6 46.Rxg6+ Bg7 47.Ne7+ Qxe7 48.Qxe7 with the queen and a pawn for three pieces and the triple threat 49.Qxd7, 49.Qf6 and 49.Ke2-50.Rag1.

C.2) 44... Nxg5 45.Ngh6+ with attack. For example, 45... Kh7 46.Nf7+ Kg8 47.Nxg5 Bxg5 48.Qxg5 Bxf5 49.exf5 winning a apwn at least and the remaining pieces will soon join the attack.

D) 43... h5 44.Nf6+ Bxf6 (44... Kh8 45.Nxd7 Qd8 46.Rxg6 wins) 45.gxf6

D.1) 45... Kh7 46.Ne7 Nh8 (46... Bg4 47.Rxg4) 47.Nxg6 Nxg6 48.Qxh5+ wins.

D.2) 45... Nh8 46.Nh6+ Kh7 47.Bd1 and the threat 48.Bxh5 seems to win.

D.3) 45... Bxf5 46.exf5 looks lost for Black.

Jun-14-15  RandomVisitor: On moves 38 and 40 white might have tried Rg1 with the idea of then playing Rh1. The queen and rook lined up on the h-file are quite a threat.

  patzer2: Here's my look at the game and the Sunday puzzle position with the Opening Explorer and Deep Fritz 14x64:

<11...Nd7> The much more popular move is 11... Qc7 as in Black's win in I Saric vs M Bartel, 2015

<12. Kh1> This is a rare try, which is probably because Black has several good options to equalize.

<12...Re8> This seems to be as good as any of Black's options.

Other playable moves include 12... exd4 as in Navara vs Mecking, 2009, 12... Rb8 as in A Berelowitsch vs M Bartel, 2014 and 12... Bb7 as in Kramnik vs Ponomariov, 2003.

<13...Nb6> This is the only game with this move in the opening explorer. Perhaps more prudent here is 13... Nf8, which uses a Knight to help defend the Kingside, as in Bologan vs Romanishin, 2005.

The remainder of the game features the development of a Kingside attack by white, and an unsuccessful attempt by Black to move pieces over from his congested Queenside to help defend the under-proteced King.

<42...h6?> Up until now Black has defended reasonably well against White's Kingside attacking plan. However, this move is a mistake, which allows White the clearly decisive winning move solving yesterday's Sunday puzzle.

Instead, 42...h5! puts up much more resistance as play might continue 43. Nxe7+ Qxe7 44. Rf3! = to with a difficult, unclear position.

<43. Ng4!!> This surprise winning move (assessing +2.75 @ 20 depth, Deep Fritz 14x64) solves our recent Sunday puzzle.

<43...hxg5>

If 43... gxf5, White wins with 44. Nf6+ Bxf6 45. gxf6+ Kh7 46. exf5 e4 47. Qh5 Nc3 48. Rg7+ Kh8 49. Qg6 .

If 43... Kh7, White wins after 44. Nxe7 Qxe7 45. Nf6+ Kh8 46. gxh6 Rg8 47. Bxa4 Rxa4 48. f4 Raa8 49. f5 g5 50. Bxg5 Rxg5 51. Rxg5 Nxg5 52. Qxg5 Rf8 53. Qg7+ Qxg7 54. hxg7+ Kxg7 55. Nxd7 .

If 43... Bxf5, White mates following 44. exf5 hxg5 45. Qh3 Qg7 46. fxg6 e4 47. gxf7+ Kf8 48. Ra2 c3 49. Bxe4 Nb6 50. Rxc3 Na4 51. Rc7 Rd8 52. Ne3 Bf6 53. Nf5 Qg6 54. Nd4 Qxe4 55. Qh7 Qxh7 56. Ne6#.

If 43... Kh8, White mates after 44. Nxe7 Qxe7 45. Nf6 Nb6 46. gxh6 Rg8 47. Rf3 Raa8 48. Be3 Na4 49. Kg2 g5 50. Qh5 g4 51. Rf5 Bxf5 52. Qxf5 Ng5 53. Bxg5 Rxg5 54. Qxg5 Nc3 55. h7 Qg7 56. Qxg7+ Kxg7 57. Nxg4 $18) 44. Bxg5 Nxg5 (44... gxf5 45. Nf6+ Bxf6 46. Bxf6+ Qg7 47. Rxg7+ Kf8 48. Rg6 Be6 49. Qh7 Ke8 50. dxe6 R6a7 51. Qg8#.

<45. Ngh6+ Kh7 46. Nf7+ Kg8 47. N7h6+ Kh7 48. Nf7+ Kg8 49. Nxg5 Bxg5 50. Rxg5 Be8 51. Kg2 R8a7 52. Rh1 Qf6 53. Nh6+ 1-0>

Black resigns in lieu of 53...Kf8 (53... Kg7 54. Ng4 Qd8 55. Qh8+ Kf7 56. Rh7#) 54. Rf5! .

  patzer2: <RV> Was wondering if you could show what Rybka finds after 42...h5 43.Nxe7+ Qxe7 44.Rf3 Kg7 45. Rf6!

Fritz's assessment initially says it's equal @ 20 depth , but when I go to the last move of it's evaluation and reassess it's near a winning advantage for White.

Jun-15-15  paramount: hello anyone thinking its better puzzle when 41??
41.Nf5!!

Not 43?? !!!

Is it more appropriate??

  patzer2: <paramount> 41. Nf5!? with best play (i.e. 41. Nf5!? h5!) is probably not a forced win, and that's my guess as to why it wasn't picked as a puzzle.

However, it's fun to analyze:

If 41...gxh5, then 42. Qh5! (threatening 43. g6!) wins.

If 41...Bd8!, then 42. Qh2 = is a level game.

The line 41...Qf8 42. Nh2!? h5! 43. Nxe7+ Qxe7 44. Rf3! Kg2 45. Rf6! = to is difficult but it might give White winning chances.

Jun-16-15  paramount: <patzer2>

Most of your post, i cant deny its true.

But you say <41.Nf5!?>. Only this i dont agree. The question mark at the end of it isnt needed because 41.Nf5!! is the best play. I use engine to check it (Stockfish 6) and at the depth 34 ply it has point +1.30 for white.

Of course that is not a level game. This is a slight advantage for white, doesnt matter what black response.

And the fact that Nisipeanu found the move, that means it is still reachable by human mind.

thanks for the attention.

<If 41...Bd8!, then 42. Qh2 = is a level game.> This is not true.

41...Bd8! 42.Qh2 is not a level game

It is an advantage for white.

41...Bd8
42.Qh2! (Qh1!! is better) Nc3
43.N3h4 Nxd5
44.exd5 R6a7
45.Rf3.....this means

So even the response 41...Bd8 isnt strong enough for black to level the game.

One way or two, Nisipeanu has scratch these lines, it MUST BE because 41.Nf5!! looks risky at first sight, but for a GM this is the proper lines.

So....the 41.Nf5 is a MUST.
