6/07/2008 14:03:34 Play online chess | Subject: Philidor Position?
Message: Recently I studied the Philidor and Lucena Positions. Although the Lucena is straightforward enough, I understand the basics of the Philidor but am not sure about how to apply it in an actual game situation or when exactly it comes up. I just finished this game, and I think that around move 66 I missed a chance to utilize this drawing resource. Can anybody tell me if I did?

Message: You are right you reached Philidor's position (or something very much like it) several times and could have drawn easily.
The position 60.Rxf4 should be an easy draw, not sure why you gave away your f6 pawn, even so it was all still easily drawn, because your king was on the promotion square. With 67...Ra6+ you nicely set up a third (sixth) rank defence (=Philidor's position) which easily holds the draw.
69...Ra7 is still a draw, but why bother with taking the rook of the 6th rank?? Just wait until his pawn has advanced far enough to not give his king any place to hide from checks and then go to the first rank and check him.
In the same sense 71...Ra6 was the right move. 71...Ra5 looses - white could have played 72.Kf6, but he missed that, after 72.Rh7 you could once more have held it with 72...Ra6.
After missing that the defence became more complicated. 75...Re1 would still have drawn for black, but it's harder to do. 75...Kf8 looses. However white doesn't really know what he's doing 77.Ra5 is a pointless move that throws away the win, the rook is great on the 8th rank and one should just play 77.Kd6 to advance the pawn (and if Rd1+ then Ke7).
After 86...Kf7 you've once more got a nice third rank defence, but you once more go for the wrong kind of continuation with 87...Ra5 and this time white punishes it properly and doesn't let the win slip away, again.

Message: Thanks for the detailed analysis. A pure Philidor position, then, is reached when the pawn is on the sixth rather than fifth rank? That is what had thrown me off - once I was at move 70 or so, I assumed that I had already missed my chance. ——— Two Draws and a Blunder in Dortmund — One of the eternal frustrations of chess is that a well played game can be lost with one careless move. Shakhriyar Mamedyarov of Azerbaijan, the No. 6 chess player in the world, was reminded of this on Wednesday at the elite Sparkassen Chess-Meeting in Dortmunt, Germany. In Round 6, Mamedyarov was White against Arkadij Naiditsch of Germany. Mamedyarov got a clear edge out of the opening and had his opponent under pressure for much of the game. Naiditsch defended well and the game seemed to heading for a draw when Mamedyarov blundered, taking a knight with his rook that was defended by Naiditsch’s queen. As chess blunders go, it was not exactly colossal, but ...

Much better than asking on a forum IMHO ——— Shankland Is US Junior Chess Champion — Samuel Shankland, an 18-year-old international master, survived a three-way playoff on Tuesday to win the United States junior chess championship. Shankland was the No. 2 seed, but he beat Ray Robson, the top seed and a chess grandmaster, in an Armageddon game to claim the title. As there were three players tied for first, there were two playoff games. Robson, by virtue of having the better tie-breaker scores, met the winner of the first game. In that one, Shankland beat Parker Zhao. The playoff involved long Armageddon games, just like the one used at the U.S. Chess Championship earlier this year. Shankland and Zhao, each chess player secretly bid on how much time, up to ...

Message: The position with your king on/next to the promotion square, your rook on the 6th rank as black (or 3rd rank as white) and his pawn on the 5th rank is what is called Philidor's position (or the third rank defence). The way to draw it is to keep the rook on the 6th (3rd) rank until he advances the pawn beyond to the 6th rank, then the rook goes to the first (8th) rank and keeps checking the king. ——— Krush Is US Women's Chess Champion; Playoff Will Decide US Junior — Irina Krush, 26, won the United States Women’s Championship on Monday by defeating Abby Marshall, 19, in the final round of the chess tournament. Krush finished with 8 points. It is Krush’s third title. She previously won in 1998 and 2007. For winning this time, she earned $16,000. Krush’s principal rival, Anna Zatonskih, 32, the 2009 champion, who was tied with Krush before the final round, could only draw against Sabina Foisor, 20. She finished with 7.5 points and tied for second with Tatev Abrahamyan, 22, who beat Katerina Rohonyan, 26. Zatonskih and Abrahamyan each earned $10,500. Krush’s win over Marshall was not easy. Marshall, playing in her first U.S. Chess Championship, had ...

——— Mamedyarov Leads in Dortmund — Shakhriyar Mamedyarov of Azerbaijan took over the lead of the elite Sparkassen Chess-Meeting tournament in Germany on Sunday after he drew his game while his co-leader, Ruslan Ponomariov of Ukraine, lost.

Message: ... Wikipedia has really excellent chess articles, much better than anything any of us might write on the forum. So that should be the first resource IMHO.
Of course if the purpose of the topic is fun that forum is better :) ——— Viktor Laznicka seals runaway World Open victory — The World Open in Philadelphia has been staged annually since the early 1970s, and although it has never quite justified its grandiose title it is still a huge magnet for chess players from grandmasters to novices. It is a big money event, with high entry fees but first prizes of several thousand dollars even for weaker sections. Its continued success reflects a ruthless policy by the organisers towards rating cheats, coupled with a highly flexible schedule. The final rounds are on Independence Day, but it is possible to compete anywhere between three and seven days and to re-enter if you start badly. For GMs in the top section, it can be a vicious battle. They normally get a minimum ...

Message: ... I certainly have no quarrel with the Wikipedia article(s) in question, having followed up the link you gave earlier. And, aware of these now, one has an easily accessible (and readable) on-line resource for the questions raised here.
But maybe I shouldn't have said "fun" - rather that a discussion of the question is a more ... social way of exploring the topic. Here, it is a more engaging way of studying this kind of endgame.
Cheers,
Ion
