 | | LIFE Master AJ: Got it, 51.NxP/e5+, and White wins in all lines. |

 | | Jimfromprovidence: To reiterate my previous point, white cannot win without his b pawn being on the board. That's why this puzzle position wins; it's not just because white has an overwhelming pawn advantage on the king side after the knight sacrifice. Play the same position below that takes the b pawn off the board and see if there is anything more than a draw for white.

"White wins with 54 Nc5, seeing b6, trapping the bishop. After 54...Ba8 (or Bc8), white follows with 55 <b>6, winning the bishop". |

| Apr-01-10 | | TheChessGuy: More Smyslovian endgame wizardry! Always look for tactics in endgames; they're out there... |
|
| Apr-01-10 | | VincentL: This week for some reason I have been lucky - the correct move has jumped out at me almost straight away most days. Here the move I see immediately is 51. Nxe5+
Then after 51..... fxe5 52. f6.
The black bishops are not well placed to deal with white's advancing K side pawns. Particularly the pawns on d4 and d5 serve as a "shield" Possible continuations:
52....gxf6 53. gxh6 and this h pawn will go on to queen.
52....g6 53. gxh6 with the same result
52....Ke8. This is the only reasonable try.
But after 53. fxg7 black is lost.
For example 53.....Kf7 54. gxh6 Kg8 55. Bc4+ with the g pawn subsequently queening. Other moves offer even less resistance.
Time to check. |

| Apr-01-10 | | VincentL: Strange last move by black. |
|
| Apr-01-10 | | Deji: <jimfromprovidence> point of correction. That should be the b and d pawns. The pawns on the king's side distract the black king and bishop and either the b or d pawn queens |
|
| Apr-01-10 | | YouRang: I'm not sure why, but the tension in the kingside pawns made 51.Nxe5+ scream, even before I worked it out. But working it out shows that 51...fxe5 52.f6 results with white getting passed pawns on the h-file, and black helpless to stop them. |

 | | eternaloptimist: I think that this puzzle is easier than the "easy" puzzle that we had earlier this week w/ 42...Rf2+. I saw the solution for today's puzzle immediately. I think it should be rated as "easy" instead of "medium". It's great to see that CG is paying tribute to smyslov this week w/ their puzzles after his death. We will definitely miss the maestro. He was truly 1 of the best chess players of all time, & he is 1 of my favorites. It is sad that he died, but we still have his games to remember him by. He was truly a genius in the endgame. |

| Apr-01-10 | | Marmot PFL: They called Smyslov the endgame virtuoso --- here the knight sac 51 Nxe5+ shortens an otherwise tedious process. 51...ef5 52 f6 and either 53 fg7 or if 52...gf6 53 gh6 and white will soon promote. |

|
| Apr-01-10 | | benjinathan: I got it in no time. Too sweet. |
|
| Apr-01-10 | | Eduardo Leon: The main (and most obvious) line is the sacrifice <51.♘xe5+! fxe5 52.f6! gxf6 53.gxh6>, and the pawn cannot be stopped.
click for larger viewBlack can deviate from this line in several ways:
First, he can play <52...g6>, but white still wins after <53.hxg6> (not <53.gxh6?? ♗h4!>). 
click for larger viewSecond, if <52...♔e8> (not <52...♔e6?>, since <53.♗c4+> eliminates all hope), white just takes the free pawns: <53.fxg7 ♔f7 54.gxh6>, and the threat <55.♗c4+> decides the game. 
click for larger viewThird, after <51...♔e7>, I think white's best sequence is <52.♘g6+ ♔e8 53.gxh6 gxh6 54.♘f4>, and, either at d5 or e6, the knight will be a dominant piece. |

| Apr-01-10 | | Chess Network: Nxe is a nice shot. Those white kingside pawns sure do move fast! :) |

| Apr-01-10 | | wals: Rybka 3 1-cpu : 3071 mb hash : depth 24:
50...h6 + 4.35 was the only blunder of the game.
fxg5 + 1.49, would have dragged it out a bit longer to 71.Qf7# |

 | | alexrawlings: Nice puzzle. A few moves before the puzzle position, I don't understand why Black didn't play 49.. Bxh5 Can anyone explain? |

<49...Bxh4> loses because of <50.Na5 Bc8 51.b6> and b7 is unstoppable |

| | tarek1: <Eduardo Leon>
(not <53.gxh6?? Bh4!>) 53.gxh6! wins as well :
<53.gxh6 Bh4 54.hxg6> 
click for larger view<54...Bxf6 55.g7> and it's over |
|
| Apr-01-10 | | Whack8888: Wow I saw this one uncannily fast. I guess as far as sacrifices go, it is the most obvious on the board. |
|
| Apr-01-10 | | Bozantium: i was looking at 55. b6 Kg8 56. b7 Bxb7 57. Bc4+ Kh7 58. g8Q+ Kxh6 59. Qg6# |
|
| Apr-01-10 | | wals: <alexrawlings)
Rybka considers 49...Bxh4 is O.K resulting in 92.Qc2#. |
|
| Apr-01-10 | | agb2002: White has a bishop, a knight and a pawn for the bishop pair. Black threatens the pawn on g5 and would play ... Ke7 to prevent pawn breaks on the king side. If we remove the pawn on f6 then 51.f6 would be decisive (51... gxf6 52.gxh6; 51... Ke8 52.fxg7 Kf7 53.gxh6). Therefore, 51.Nxe5+: A) 51... fxe5 52.f6 Ke8 (52... gxf6 53.gxh6 and the pawn promotes) 53.fxg7 Kf7 54.gxh6 Bd5 (otherwise Bc4+ and g8=Q+) 55.exd5 Bd2 56.b6 Ba5 57.b7 Bc7 58.d6 Bxd6 59.Bc4+, winning. B) 51... Ke7 52.gxh6 gxh6 53.Ng4 Bd2 54.Bc4 followed by Bd5, if Black trades bishops then the resulting N+2P vs B is won, if Black plays ... Bc8 then the maneuver b6-b7 wins. If Black plays ... Ba5 to avoid b6 then Nxh6 wins another pawn. C) 51... <other king moves> 52.gxh6 gxh6 53.Ng4 winning a third pawn. |

|
| Apr-03-10 | | kevin86: The Entourage of pawns wins it for white:let's call them Turtle,Vince,Drama,and Eric. The one at h5:just call him Ari. Just call me Ishmael-lol |
