| karlzen: 11...gxf6!? is an interesting idea, which takes play off the main line (Nxf6). Play then flows very naturally. If white tries to grab the e6-pawn on move 16 for example, black's pressure on the g4-pawn will guarantee him equality. 16...d5 opens the position for the bishop-pair and seems essential. A key move in the Sicilian. Here's an interesting line: 18.exf7! Rxg4!? 19.Rxg4 (19.Rg2! looks good, with the simple idea of Ne6) 19...Bxg4 20.Ng6+ Kg7!? (20...Nxg6 is perhaps simpler) 21.f8=Q+ Bxf8 22.Nxf8 Kh8 23.Ng6+ Kg8 24.Qb3+ Nc4 25.Bxc4+ bxc4 26.Qe3 Bxd1 27.Qxe4 Rd8! 28.Ne7+ Kh8 29.Nec6 Bh5 30.Nxd8 Qxd8  White has the better piece constellation (Q+N) and some attacking chances but it's hard for him to realise the advantage against a good player. White may create a passed pawn by b2-b4 cxb3, axb3 but as the own king needs shelter, it's hard to push. I think black should try the simple 18...Nxf7 instead: 19.Nd5 Qc5 20.Nxe7 Qxe7 21.Be2 Ne5 22.Kb1 Bd7 23.Qh4 Rad8 24.h3 Qg7 25.Qg3 Qg5 26.Nb3 Bc6 and white has a slight pull but it's hard to win since there are too few ideas with so few pieces left on an open board. I think Fischer is right about 24...Kxg8 being slightly advantageous for black, say: 25.Rxf6 Qe5 26.Qh4 Rc8. <fred leenox>, If 37...e2 then simply 38.Kf6 with the threat of mate, drawing: 38...Kh8 39.Rh7+ Kg8 40.Rc7=. <TrueFiendish>, As 53.Rc7+ is annoying, 52...Rh5 is a simple draw. It must've been mutual zeitnot. |

| Bardassottina: Why they put position after white's 57 move as today's problem? Is it not a draw in any case? It looks me very strange that Kb8 is the unique move and my Kb7 they say does not work ?! |

| Rowson: yer i think this was a awful problem... is it not an easy K vs K + P draw? |

| DevastatioN: Well, Kb7 loses the game, after Kb5 and u lose your opposition because it is your move, after Kb8 you keep the opposition with Kb5 then Kb7, or Kc5 then Kc7, there is no way for white to make progress and win if you have opposition and win. Kb7 is a blunder. |

| AliceInWonderland: A question on Sicilain: I am a chess beginner and there is something about Sicilian that keeps bothering me. Why does a typical game go 1e4 c5 2Nf3 Nc6 3d4 cxd4 ? Why doesn't black answer with 3...d6 or 3...e6 ? |

| Timetraveller: <fred lennox> 37... e2 isn't a win actually; White has 38. Kf6, and Black must play 38... Kh8 to stave off checkmate. Then 39. Rh7+ is at least a draw. |

| Helloween: <AliceInWonderland>Ask your question here: Sicilian (B20) and it will be gladly answered. |

| AntonioSonoQui: I like this special case of using the attacker's own pawn to block his path to the opposition -- it's definitely a great concept to keep in mind |

| kevin86: The idea of  + vs is for the stronger side to get the opposition IN FRONT of the pawn. With the text move-black gains the right to acquire the opposition. Once this is done,white can never chase the king away-and must then lead with the pawn.Upon doing that,the crisis position is
WK c6,P b6 BK c8-White must then play :b7+ Kb8;Kb6 stalemate. However,black must avoid at all cost-kings at c6,c8 BEFORE the pawns gets to the sixth-where black will lose,regardless who is to move. Keeping the king in opposition until the pawn advances is of course black's drawing course. |

| onthebeat1971: The people who read the first chapter of Capablanca's "Chess Fundamentals" solved this puzzle in less than a second... |

| MatrixManNe0: I'm sorry, but this was way too easy, and I think that the vast majority of people here will agree (although there are still some confused with the 'opposition'). |

|
| acirce: <MatrixManNe0> Several people had problem with this and so it was demonstrably an instructive puzzle. More of that kind! |
|

| MatrixManNe0: Yes, true, I understand that, and it's great that these people are getting feedback. I just found it easy and must have gone a little overboard by thinking of it's simplicity rather than its instructivity. |

| uponthehill: With that move, Fischer prevented enemy's king staying on opposition. In K+pawn vs. king ending, that side is sucessful (attacker wins, defender draws), whose king enters the field, which is same colored as this one which is occupied by enemy's king, and there is one other color field beetween the kings. |

| midknightblue: I am trying to figure out the theme this week. Is it...
A) Endgames
B) Opposition
C) The week of "Let's pretend everyday is monday" (a.k.a. take the week off from chessgames.com if your rating is above 800 week) |

| bob725: Just want to say thanks to everyone especially Cyphelium for the help they gave.
Understand it now! |

| ruylopez900: Although the concept was definitely basic, It was interesting trying to figure out which was the magic square Black had to reach so that White couldn't push him off the board! |

| Whitehat1963: Amazing! Is this really a draw? I'm sure I'd manage to lose it somehow. |

| Peligroso Patzer: <EXIDE: I thought that a king ahead of a pawn versus a king was a win for king and pawn with the exception of the *** a and h [files].> The rule cited above only applies if the pawn has reached the fifth rank. If the pawn is on the fourth rank (as in this game) or is less advanced, the supporting King must reach two ranks ahead of its pawn to win. If the defending King can take the direct (close) opposition whenever the attacking King steps one rank ahead of its pawn (as is possible here after 57. ... Kb8), the defending side can hold the draw. |

| 4tmac: BLACK should have defended the pawn with 52. ... R-h5! (not his R-h8?) WHITE then can win with 53. R-c7+ (or R-c5)-----57. ... K-b8! was the only move to draw |

| WhiteRook48: a very tough ending |
|
| Aug-13-09 |
| WhiteRook48: this is an odd game for Fischer |
