 | | perfidious: <mjmorri: A rather pedestrian combination giving Naka lovers the false notion that he is some sort of chess genius on an arc toward the world championship.> Which you, of course, would have unearthed in a nanosecond had you been sitting at the board. Please do us all a favour and share your improvements on Black's play, as it is plain you regard yourself as a towering genius. |
|
| Feb-14-14 | | mjmorri: <perfidious> There is nothing wrong with the combination. However, it is quite linear with not a lot of deep side variations, and no tangled messes to unravel. |
|

| | perfidious: If '(t)here is nothing wrong with the combination', then why denigrate its merits? |
|
| Feb-14-14 | | mjmorri: My complaint lies with the Naka lovers who try to extrapolate a few impressive looking games into a run to the world championship. I do not see his name among those playing in the Candidates Tournament in March. |
|
| Feb-21-14 | | Travis Bickle: Awesome chess! |

 | | MSteen: Unbelievable! Even though I knew the queen sac was the beginning of a combination, for the life of me I couldn't guess at where he was going move by move. I didn't even guess the penultimate bishop move.
Wow, just incredible. |

 | | Penguincw: Oh, this game! I saw it before, but that was 4 years ago, when I was checking out some of Nakamura's other games (notably those underpromotion games against the computers). Anyway, in this puzzle, I knew there was going to be a queen sac, but wasn't sure if the rook was going to be better placed on b6 or f6. I then chose 21...Rxf6 22.Rxb6 Rxb6, and black has a rook, bishop and pawn vs. queen. Probably a draw in this case, but if the queen sac was on f2... Tomorrow's Monday, right? |

 | | offramp: In king-hunts like this the crucial moves, the hardest-to-find moves, are the non-checks. 26...f6 is an example. |
|
| Jun-28-15 | | stacase: 24...Ne5 is where I lost the move for move track. |
|
| Jun-28-15 | | Mating Net: Tremendous combination by Naka, but way too famous to be a puzzle. Knowing the combo removes the element of doubt. |
|
| Jun-28-15 | | M.Hassan: "Insane"
Black to play 21...? and black is a pawn up.
21..........Qxf2+!
<if 22.Kh1 Rxf6 and Black gains more material> 22.Kxf2 Bc5+
A)
23.Kf1 c5+
24.Re2 Rxf6+
25.Nf3 Bxe2+
26.Qxe2 Rxe2
27.Kxe2 Rd6
Black is slightly stronger
B)
23.Kf3 Rxf6+
24.Kg4 Ne5+
25.Rxe5 Bc8+
26.Kg5 Rxe5+
27.Kh4 Rh6#
time to check |
|
| Jun-28-15 | | MindCtrol9: Micha did not think that for some reason Nakamura gave the exchange? I don't know, but 21.Rxe7 looks like White is ok.<21.Rxe7 Rxe7 22.Bxf6......>and possibly Naka is the one who heats crushed.I have to take a better look at this game, but this is what I see quickly. |
|
| Jun-28-15 | | MindCtrol9: Strategy is in my opinion is the ability to create the conditions for a tactical play.Here, in this game, Nakamura did that knowing that with the Queen sacrifice had a discover check having all his pieces in coordination to finish with 3 exclamation marks.That is why I don't use computers to post because humans have something different, the mistakes.Computers don't get tired. |
|
| Jun-28-15 | | diagonalley: black's 21st must have come like a bolt from the blue!! what a shot!! it would be interesting to know how long naka took before playing it. superb |

 | | An Englishman: Good Evening: Missed Friday and Saturday, solved Sunday. Another oddball week for me. |
|
| Jun-28-15 | | Steve.Patzer: Amazing game |
|
| Jun-28-15 | | mel gibson: White should not have taken the queen sacrifice.
Best move was 22 K h1
DR4 64 bit on i7 quad core gives a score of -3.72 depth 20.( 180 seconds )
move 22 for Kg1-h1
So white is still losing but not so quickly. |
|
| Jun-28-15 | | sfm: When you play with players who can see through 19.-,dxc4!! you know you better stay out of tactics.
I recall one early game of mine where my opponent, a young 1700-player, made a knight sac so brilliant that several master-level spectators later admitted that first several moves later understood how ingenious it was.
I remain envious. Unfortunately, he blundered a couple of moves later, destroying a beautiful game. I still somehow feel that I should rather have resigned. The prize for 'resigning at the right time for beauty' goes to McDonnell in this game
McDonnell vs La Bourdonnais, 1834 |
|
| Jun-28-15 | | morfishine: I had <21...Qxf2+> and the White King is cornered after 22.Kxf2 Bc5+ 23.Kf3 Rxf6+ But <MindCtrol9> makes a very good point: White missed his chance immediately prior to the Queen sac: Instead of 21.Bxf6? much better is 21.Rxe7! Nice post
***** |
|
Jun-28-15
| | offramp: I can imagine Michal Krasenkow playing 21.Bxf6 quite happily. Then the sense of unease rises in him as he sees Nakamura focusing on his f2-pawn. It has only happened to me about 200 times. |
|
| Jun-28-15 | | gofer: Lets see...
White threatens Rxb6, Rxe7, Bxe7 and Bxc6 - all with a significant material gain! Black threatens Qxf2 - losing its queen for a pawn!??! Hmmm, so who's winning this one??? Black obviously!
<21 ... Qxf2+>
22 Kh1 Rxf6 
<22 Kxf2 Bc5+>
The whole point of the queen sacrifice, draw the white king into the middle of the
board. The poor king has nowhere to hide!
23 Kf1 c3+!
24 Re2 c2!
25 Qxc2 Bxe2+
26 Ke1 Bd3+
27 Kd1 Bxc2+
28 Kxc2 Rxf6
<23 Kf3 Rxf6+>
<24 Kg4 Ne5+!>
At this point, I would be quite happy as black. The king is getting cornered very nastily and Rxe5 loses to Bc8+, 25 Rxe5 Bc8+
26 Rf5 Bf5+ mating
<25 Kg5 ...>
Now at this point it gets tricky, so I am going to give up! ~~~
Nakamura makes it look easy! But it really isn't!!!! |
|
| Jun-28-15 | | nalinw: Got a Sunday puzzle - and almost all of it too - without seeing it before at all. On the other hand .... Qxf2+ is the only move worth a Sunday puzzle - and once that is found the follow-up may not be quite at the same level. Didn't get Thursday, Friday and Saturday at all - TGIM tomorrow! |
|
| Jun-28-15 | | patzer2: Here's my look at the game and the Sunday puzzle (21...?) with the chessgames.com Opening Explorer (OE) and Deep Fritz 14: <1. Nf3 Nf6 2. c4 e6 3. g3 d5 4. Bg2 Be7 5. O-O O-O 6. b3> By far the most
popular move (and my preference) is 6. d4 as in Aronian vs Kramnik, 2015. <6... a5> This seldom played move has scored well for Black in practice. Out of 54 games in the OE with this move, Black won 35.2% and White won 24.1%. Most often played here (525 games in the OE) is the computer (i.e. Fritz) choice 6...c5 as in A Giri vs Anand, 2015. <7. Nc3 c6 8. d4 Nbd7 9. Qc2 b6 10. e4 Ba6 11. Nd2> Here Fritz slightly prefers 11. e5 Ne8 12. Nd2 = as in
Timman vs H Karner, 1973. <11... c5> The game apparently enters unexplored territory, as this is the last game with this move in the OE. After 11...c5, Black is fully equal if not slightly better. <12. exd5> Perhaps better here is Fritz's first choice 12. e5 = when the computer indicates play might continue 12...Ng4 13. Qd1 h5 14. h3 cxd4 15. Nxd5 exd5 16. hxg4 Nxe5 17. Bxd5 Nxg4 18. Ne4 Ra7 19. Qxd4 Rd7 20. Re1 Bb7 21. Bb2 Bf6 22. Nxf6+ Nxf6 23. Re5 Bxd5 24. cxd5 Rxd5 25. Rxd5 Qxd5 26. Qxb6 Ne4 27. Qd4 Qxd4 28. Bxd4 =. <12...cxd4 13. Nb5 exd5 14. Nxd4 Rc8 15. Re1> If 15. a4, Black secures the advantage with 15...Ne5 when play might continue 16. Nb5 Bxb5 17. axb5 Qc7 18. Bb2 dxc4 19. Bxe5 Qxe5 20. Rae1 Qg5 21. Rxe7 cxb3 22. Qd3 Rcd8 23. Ne4 Rxd3 24. Nxg5 Re8 25. Rb7 h6 26. Nxf7 a4 27. Ra7 b2  . <15... b5 16. Bb2 Re8 17. Qd1 bxc4 18. bxc4 Qb6 19. Rb1 dxc4 20. Nc6 Rxc6> Black has won a pawn and White has no compensation for it. <21. Bxf6?> This loses quickly to Black's stunning reply. As <MindCtrol9> observes, White can put up more resistance with 21. Rxe7, when there's practical drawing chances against a human opponent. However, 21. Rxe7 is not a sure-fire panacea as Fritz indicates it loses to strong play after 21... Rxe7 22. Bxf6 Nxf6 23. Rxb6 Rxb6 when play might continue 24. Qc1 h6 25. h3 Rd6 26. Nf1 Rd3 27. Ne3 c3 28. Bf1 Rdxe3 29. fxe3 Bxf1 30. Kxf1 Nd5 31. Ke2 Rxe3+ 32. Kf2 Rd3 33. Qe1 Ne3 34. Ke2 Nc2 35. Qc1 Rxg3 36. Qf4 Rg2+ 37. Kf1 Rg5 38. Qb8+ Kh7 39. Qf4 Nb4 40. a3 Nd5 41. Qe4+ g6 42. Ke2 f6 43. Qb1 Re5+ 44. Kd3 h5 45. h4 g5 46. hxg5 Rxg5 47. Kd4+ Kg7 48. Qb7+ Kh6 49. Qb1 Re5 50. Qh1 c2 51. Qf1 h4 52. Qh1 Nc7 53. Qc1+ Kh5 54. Qxc2 Ne6+ 55. Kd3 Nf4+ 56. Kc4 h3 57. Kb3 Kg5 58. Ka4 Re2 59. Qb3 h2 60. Qg3+ Kf5 61. Qh4 Ra2 62. Kb5 Nd5 63. a4 Nc3+ 64. Ka6 Ke5 65. Qh5+ f5 66. Qh8+ Kd5 67. Kxa5 Ne4 68.

| Jun-28-15 | | patzer2: <21... Qxf2+!!> This surprise Queen sacrifice, which I missed, begins a decisive King hunt with the minor pieces and solves today's Sunday puzzle. My weak attempt at a Sunday solution was 21... Rxf6?, which misses the win and loses after 22. Rxb6 Rxb6 23. Nxc4 Bxc4 24. Qxd7 Bb5 25. Qc7 Rd6 26. Bf3 Bf8 27. Rxe8 Bxe8 28. Qxa5  . <22. Kxf2 Bc5+ 23. Kf3> If 23. Kf1, then c3+ 24. Re2 c2 25. Bxc6 cxd1=Q+ 26. Rxd1 Bxe2+ . <23... Rxf6+ 24. Kg4 Ne5+!> This follow-up is essential. Other moves give White a level game or better. For example if 24... Rg6+?, White holds after 25. Kh3 Rh6+ 26. Kg4 Rd8 27. Bb7 Nf6+ 28. Kf4 g5+ 29. Kf5 c3 30. Bxa6 Rxd2 31. Re2 Rxd1 32. Rxd1 Kg7 33. Rc2 =. <25. Kg5> White's King has no escape from Black's minor piece mating web. If 25. Kh4, then Rh6+ 26. Kg5 Rg6+ 27. Kf5 (27. Kh5 Bc8 or 27...f6 ) 27... Bc8+ 28. Ke4 Rd6 29. Kf4 Nd3+ 30. Kg5 Rxe1 31. Qf3 Rg6+ 32. Kh5 Rh6+ 33. Kg5 Be3+ 34. Qxe3 f6#. If 25. Rxe5, then Bc8+ 26. Rf5 Bxf5+ 27. Kh4 Rh6+ 28. Kg5 Bc8 29. Nxc4 Rg6+ 30. Kf4 Rf6+ 31. Kg5 Re5+ 32. Nxe5 Be3+ 33. Kh4 Rh6+ 34. Qh5 g5#. If 25. Kh5, then Bc8 26. Ne4 Rf5+ 27. Ng5 g6+ 28. Kh4 Rf4+ 29. g4 Bf2+ 30. Kh3 Rxg4 31. Bf1 Rg3+ 32. Kh4 Rg1#. <25... Rg6+ 26. Kh5> If 26. Kh4, then Be7+ 27. Kh3 Rh6+ 28. Qh5 Rxh5#.
If 26. Kf4, then Nd3+ 27. Kf3 Rf6+ 28. Kg4 Bc8+ 29. Kh4 Rxe1 30. Qxe1 Rh6+ 31. Kg5 f6#. <26... f6 27. Rxe5 Rxe5+ 28. Kh4 Bc8 0-1> White resigns in lieu of 29. Bd5+ Rxd5 30. g4 Rd3 31. Qf3 Bf2+ 32. Kh3
Rxg4 33. Rb8 Rg3+ 34. Kh4 Rh3#. |
