|Jul-24-07|| ||WannaBe: White can't convert the 2 pawn advantage? Or is it just good play by black?|
|Jul-24-07|| ||nescio: <WannaBe> Once again it is confirmed that K+R+RP+BP can't win against K+R. According to endgame theory it's a draw, but grandmasters will often try just the same, and we benefit from their will to win.|
|Jul-24-07|| ||arunjangity: hmm, wonder if zhu chen was actually the one who insisted in playing on in Nakamura vs Zhu Chen, 2004 ...at least marmot's comment there supports that theory|
|Jul-24-07|| ||WannaBe: <nescio>, <arunjangity> Thank you, one would 'think' that with 2 pawn adv. even if you sac one of the pawn, and force your focus to defend/protect/promote the other, it would be queened.|
|Jul-26-07|| ||nescio: The problem is that many positions with one pawn are drawn. One of them we see here.|
With BP and RP, the weaker side has to avoid that his king is forced to his back rank, as in Capablanca vs B Kostic, 1919
A classic example of perfect play: Gligoric vs Smyslov, 1947

|Jan-20-08|| ||Resignation Trap: Since the game http://www.chessgames.com/perl/ches... earlier this week, I've been looking at this particular endgame with great interest.|
With the help of this tablebase: http://www.shredderchess.com/online... I'll examine the key positions of this game.
Black plays the endgame correctly until

Her 69...Kg6? loses,
69...Rc1 is the only move to draw.
The game is now a forced win for White, but she doesn't seem to know how to do it.
Eventually, we arrive here:

White errs with 80.Rd6? Kg7 81.Rd7+ and now Black returns the favor with 81...Kf6? (81...Kh8 draws). And White again replied with 82.Rd6+?
The most straightforward win for White is 82.Kd4 Kg6 83.Re7 Rd8+
84.Ke4 Kf6 85.Rd7 Rc8 86.Kf3 Kg6 87.Kg4 Rb8 88.f5+ Kf6 89.Kh5 Kxf5 90,Rf7+ Ke6 91.Kg6 Ke5 92.Kg7 and the Pawn Queens.
|Jan-20-08|| ||whiteshark: <Resignation Trap> Do you have "Rook Endings" by Levenfish/Smyslov? In chapter three vs +, subchapter disconnected pawns, are some more examples (see also chapter 'Conclusion' - no.5)|
|Jan-20-08|| ||Resignation Trap: <whiteshark> No, I don't have that particular book, but I'm compiling other example of this endgame in my collection: Game Collection: Oh, Those Effin' Aitch Pawns in Rook Endgames! . I'm looking at missed opportunities for winning and typical errors in defending.|
