|Sep-21-07|| ||Wolfgang01: Moro played not that good in this tournement. May the fortune be on his side in this game for a draw.|
|Sep-21-07|| ||Marmot PFL: Well Moro is the one who is thinking so maybe he is searching his memory banks. If Lev get up & walk around room with a big smile on his face that might disconcert Moro.|
|Sep-21-07|| ||radu stancu: <acirce> Yeap, we're in Kholmovland. I'm still glad we got to see this, else who knows when I would have gone back to Anand-Kramnik and seen your post there. I just hope Aronian won't drag this forever once he sees that g4 won't help either.|

Lev needs something stronger. Like when Kasparov was putting his watch back at his wrist. :)

Here, 5...Ra6+, then 6...Rxa7.
|Sep-21-07|| ||plang: It looks to me like Aronian is making progress.|
|Sep-21-07|| ||tal lover: no progress|
|Sep-21-07|| ||Marmot PFL: This will trade down to draw with 2 rook pawns.|
|Sep-21-07|| ||SCUBA diver: If K-g5, f4+. ..|
|Sep-21-07|| ||badest: Some progress ... just a very roundabout way to get the f-pawn. Draw.|
|Sep-21-07|| ||Eggman: Draw agreed, finally.|
|Sep-21-07|| ||JointheArmy: Good to see Morozevich knew of Kholmov's position. Levon is well read as well - he stated this in his Misha interview - so I'd be surprised if he didn't know of this position.|
|Sep-21-07|| ||radu stancu: And a draw it is. Nice defense by Moro.|
|Sep-21-07|| ||tal lover: <chessgames.com> lets change to Leko-Grischuk.|
|Sep-21-07|| ||Ulhumbrus: In the position after 42 Ke1, with White's f pawn on f2 and not on f4, and the Black K on h7, here is one reason for not capturing Black's e4 pawn: it can shield a King on e6, as follows. Suppose the White K can reach b6. Then here is one variation: 1 Kb6 Rb1+ 2 Kc6 Rc1+ 3 Kd6 Rd1+ 4 Ke6 Now with a Black P on e4, Black lacks the check 4..Re1+ so the Rook has to go back to a1. 4...Ra1 5 Rd8 Ra6+ 6 Rd6 Rxa7 7 Rd7+ Rxd7 7 Kxd7 Kg7 8 Ke7 Kh7 9 Kf7 Kh6 10 Kg8 g5 11 Kf7! gxh5 11 gxh5 winning|
|Sep-21-07|| ||tal lover: <Ulhumbrus> i think the best for black is 1.Kb6 Rb1+ 2.Kc6 Ra1. now if white king goes to d6 Ra6+ and if white plays Rd1 the king and pawn endgame is a draw. There is no win|
|Sep-21-07|| ||ounos: I like 23. ...Reb8 by Moro very much. Quite unique.|

|Sep-23-07|| ||notyetagm: More great explanations from GM Ian Rogers at the USCF website:|
<The rook endgame, which was similar to the Anand-Kramnik game in round 3, was winning for White until 36.h4?, although the reason is very subtle.
In the game Morozevich could afford to give up the e pawn, because after 36.h4 there is no way for White to create a passed f pawn, something which is needed if White is to dislodge the Black king from its shuttle between h7 and g7. (See Jeremy Silman's Endgame Course for full details.)
If the White pawn had stayed on h2 then, when the black pawn reaches a7 and the White king reaches d5 and the Black king is on ...h7, Black will have to defend the pawn with ...Ra4 - something Morozevich did not have to do in the game.
Then White plays Kc6! Ra1 Rd8! Rxa7 Rd7+ with a winning pawn endgame - the sort of idea that Kramnik tried without success to organize against Anand.>
Does anyone know the exact section of Silman's book that GM Rogers is talking about? Could someone point out the analogous section in the Dvoretsky Endgame Manual that discusses this type of endgame?
|Sep-23-07|| ||euripides: <Notyet> Marin on chesbase seems to suggest that if White does not play h4 Black can draw by playing g5-g4 and White can never create a passed f pawn. |
However, Rogers might be right. If White plays h3 and Black plays g4, White can exchange on g4 leaving Black pawns on e4 and g4. White can then play Kd5 when the rook is on e4 and Black's king is on h7, producing zugzwang. If Black then plays Kg7 White has Re8 Rxa7 Rxe4 and the g4 pawn will also fall. <acirce> pointed this out on the tournament page and referred to a game involving Nielsen where this structure lost for Black.
|Sep-23-07|| ||euripides: <notyet> Also, for a summary of Dvoretsky's explanation of the crucial endgame, see <acirce>'s kibitz with diagram on the Anand-Kramnik game.|
|Sep-23-07|| ||percyblakeney: If I understood the Chesspro report correctly Morozevich explained after the game that the endgame was won for Aronian (before 36. h4) and also showed how, even if they didn't go into the details.|

Yes, Morozevich knew that he was lost but kept playing, hoping that Aronian would make a mistake. 36 h2-h4? was the mistake he was hoping for and voila, drawn rook endgame.
|Sep-23-07|| ||adair10: Aronian himself called his 36.h4 move something like "childish move".|
