 | | kevin86: This puzzle is a perfect corrollary to today's GOTD. In both cases,white is able to hold a draw though down a rook for a queen. Here,the pawns immobilize black's pawns and serve as a resting spot for his rook on the fifth row. Black can make no progress-the game is drawn. |

Aug-20-06 | | Knight13: <sharkbenjamin: Wow! What a draw? Never give up!> Ummm... Many people under 1600 always plays until they're checkmated so... I guess this only applies to stronger players. |

Aug-20-06 | | dzechiel: Missed it. I didn't even consider a fortress approach. Spent all my time looking for some sort of stalemate combination (without success, I might add). |
|
Aug-21-06 | | Trouble: Nice problem. still takes some accuracy to make sure black doesn't trade the queen for the rook |
|
Aug-29-06 | | LIFE Master AJ: White to move ... on turn # 45. Does anyone know what day this was the POD ("Problem Of the Day") on? |

Jun-15-08 | | LaFreaK: Guys,consider 48...Qe6 instead of Kg6. |

 | | whiteshark: With <42...Rxe2 43.Kg3 Ng2! 44.Nd4 Rd2 45.Rc7 Kg7 >  click for larger view Black should more probably have won. |
|
Jan-25-09 | | WhiteRook48: Queen against Rook? And white draws?? Weird |
|
Mar-01-09 | | WhiteRook48: nice tactic |
|
Sep-21-09 | | WhiteRook48: i think black had a win somewhere in the ending |

 | | FSR: <whiteshark> Yes. Gisbert Jacoby (who?), analyzing the game in Mega Database 2013, gives <42...Rxe2+ 43.Kg3 g5? (Dies ist ein Fehler. Springerzüge ergeben eine klar gewonnene Stellung
für Schwarz.) (43... Ne6 ; 43...Nd5 ; 43... Ng2! 44.Nd4 Rd2 45.Rc7 e2 ) 44.Rxf4! (44. -- Rg2#) 44...gxf4+ 45.Kxf4= (Mit Gewinn des
schwarzen e-Bauern und Remis-Chancen für Weiß. Diese Variante hatte
Kortschnoj gesehen. Deshalb zog er nicht 42...Rxe2+.) > I don't know what the German means, but the punctuation is easy enough to grasp. |

 | | al wazir: What was the point of 41...Kh7 ? Doesn't 41...Nxe2 win? |
|
Aug-27-13
 | | FSR: <al wazir> Probably. My guess is that Korchnoi was in time pressure and didn't want to commit to ...Nxe2 unless he was 100% sure that the resultant endgame was winning. (If the time control was at move 40, he may not have been sure that he had made it yet.) He was also worried that if he played a waiting move White could play 42.Nf5+ and trade off knights. So he played 41...Kh7, avoiding Nf5+ but otherwise sitting on the position. Salov was in desperate straits - obviously <he> couldn't afford to just play waiting moves - and probably had been contemplating Nf5+, so after 41...Kh7 he tried to create maximum confusion by playing 42.Nf5!? anyway. Mirabile dictu, it worked! |

 | | al wazir: <FSR: Probably. My guess is that Korchnoi was in time pressure>. All right, but the time control was usually at 40 moves. |
|

 | | FSR: <al wazir> As I said, "If the time control was at move 40, he may not have been sure that he had made it yet." That's how it is if the players are blitzing out moves and haven't been filling out their scoresheets. Or even if you think you've made it, you want to make 100% sure so you play an extra move. I think Nakamura had a game a year or so ago where he flagged through erroneously thinking that he'd made the time control. |

Aug-27-13 | | Caissa4ever: 25... e3 !
The main goal is to weaken the shield of the white king, as the exchange is even |
|

 | | kevin86: White is down a queen for a rook...but can hold the draw. |
|
Aug-27-13 | | psmith: FSR: The German means, roughly
42...Rxe2+ 43.Kg3 g5? (This is a mistake, Knight's moves yields a clear winning position for Black.) (43... Ne6 ; 43...Nd5 ; 43... Ng2! 44.Nd4 Rd2 45.Rc7 e2 ) 44.Rxf4! (44. -- Rg2#) 44...gxf4+ 45.Kxf4= (With win of the black e-pawn and drawing chances for White. Korchnoi saw this variation. Therefore he did not play 42. Rxe2+.) The meaning seems to be that Korchnoi missed the winning Knight's moves after 42... Rxe2+ 43. Kg3 and only considered 43...Rg2+ yielding drawing chances. |

 | | FSR: <psmith> Thanks. |
|
Aug-27-13 | | psmith: (I meant "only considered 43...g5" -- of course.) |
|
Aug-27-13
 | | Penguincw: The 2 pawns on both side prevent a win for black. |
