Dec-05-07		apple pi: <This was not the case, however, with Wang and Cheparinov, who after shaking hands upon the games end, put all the pieces on the board again and played multiple blitz games for a few hours.> Now that's stamina!!!

Dec-05-07		fligorna: Is it truth? The Khanty winner will play with TOPA??

Dec-05-07		dumbgai: I'm quite sure Cheparinov wouldn't have played the extra blitz if he didn't have a rest day in between. :) Even though I was rooting for Wang Yue, Cheparinov's play is very impressive in this game. A match between him and Topalov would certainly be very interesting.

Dec-05-07		ikipemiko: Chepa was the clear favourite in this mini match! I think that the future of chess is in the hands of Sergey, Magnus and Ivan - and it will be bright future!

Dec-05-07		Honza Cervenka: <Chepa was the clear favourite in this mini match!> Cheparinov is very talented player but his rating is somewhat lower than Wang Yue's (despite of the fact that Wang Yue is the younger of them) and his score with Wang Yue was 0:2 before this minimatch according to games in this database. Chepa was hardly "the clear favourite" here.

Dec-05-07		ikipemiko: Yes, Chepa has a lower rating and has a negative score against Wang but it seems that you didn't watch Chepa of lately (last year).

Dec-05-07		badest: Well, if the "live" rating is correct, Chepa actually had 10p or so higher ELO than Wang (before the mini-match).

Dec-05-07		s4life: <Jim Bartle: "Simple and nice." With a knight under attack, black throws a bishop and a rook into the fire. I guess it's not that tough to see black will get a piece back and leave the king isolated, but it got complex after that. (For me at least)> I am happy to see Chepa reach new heights while being true to his uncompromising attacking style.. good luck tomorrow!

Dec-05-07		cotdt: Cheparinov is as hot as ice. If you've ever been to heaven, this is twice as nice.

Dec-05-07		jhoro: <ikipemiko: Yes, Chepa has a lower rating and has a negative score against Wang but it seems that you didn't watch Chepa of lately (last year).> Ivan lost both games to Yue this year in July. I don't think there are clear favourites in any of the pairings though i find Ivan's been playing very solid chess in this cup so far. this game in particular looks very nice

Dec-05-07		Mateo: g3 was the good move but Wang Hue didn't play it at the right time. 26.g3 was too late, allowing a brilliant double sacrifice. But 25.g3 was good, before the Bishop arrives on the a3-f8 diagonal. If 25...Bf8? (25...Nh3) 26.gxf4 Bxa3 27.bxa3 Rxa3+ 28.Kxa3 Qb4+ 29.Ka2 Ra8+ 30.Na4 Rxa4+ 31.Qxa4 Qxa4+ 32.Kb2, White has some material edge. IGM Rozenko says on Chessbase that 23.Ka2? was the turning point. I think is wrong. 25.Rd2? was the blunder giving Cheparinov a winning attack, meanwhile 25.g3 holds.

Dec-05-07		halloween: So, what about the underpromotion on move 40? Was that really the swiftest way to a win for Chepa... or was he trying sadistically to prolong the torture?

Dec-05-07		JointheArmy: <Was that really the swiftest way to a win for Chepa> Yes it was.

Dec-05-07		jhoro: <So, what about the underpromotion on move 40?... > that was the only way to avoid perpetual checks

Dec-05-07		cotdt: This kid has a playing style exactly like Topalov's

Dec-05-07		chancho: If Chepa wins the final, and he plays Topa, and wins, then you'll have Darth Sidious, er, Danailov saying: Now take your place at my side my young apprentice...

Dec-06-07		danbotea: Bravo, Cheparinov ! Really nice!

Jan-02-08		Saggi: chepa is great

Mar-17-24		An Englishman: Good Evening: Solved it, brilliant attack, but did not expect Yue Wang to last so long. Remarkably tenacious defense. Flubbed 4, already knew 1, solved 9 for the week. Satisfactory.

Mar-17-24		mel gibson: I thought either 26. ..Bxa3 or 26. .. Nd3 Stockfish 16 follows the game ply: 26. .. Bxa3 (26. .. Bxa3 (1. ... Bxa3 2.bxa3 Rxa3+ 3.Kxa3 Qb4+ 4.Ka2 Ra8+ 5.Na4 c3 6.Rf2 Rxa4+ 7.Qxa4 Qxa4+ 8.Kb1 Nh3 9.Ra2 c2+ 10.Rxc2 fxe4 11.f4 exf4 12.gxf4 Nxf4 13.Ra2 Qd4 14.Rc2 e3 ) +5.85/42 258) score for Black +5.85 depth 42. If I get SF to try my other choice it still wins but is not as strong: 26. Nd3 Nd3 (26. .. Nd3 27. Rxd3 (1.Rxd3 cxd3 2.Nxd3 fxe4 3.fxe4 Qd4 4.a4 Bb4 5.Nxb4 Rxb4 6.Rd1 Qc4+ 7.Kb1 Rf8 8.a5 Rfb8 9.Rc1 Qa6 10.Nd1 Qxa5 11.Qc6 R4b6 12.Qxc7 Qe1 13.Qxe5 Qe2 14.Qc3 Qxe4+ ) -2.78/49 299) score for White -2.78 depth 49.

Mar-17-24		Teyss: Fantastic combination throughout, culminating with 40...d1=N+!! If 40...d1=Q? 41.Qe7+ Kg8 42.Qe8+ or 41...Kh6 42.Qg5+ perpetual: hence Black's objective is to control e7 or take the f4 Pawn. If 41.Kb1 or Kc1, also Ne3+. If 41.Ka3 or Kb3 or Kc3, Qf3+ and Qxf4. Earlier, the key is probably resisting 30...Rxa4+ 31.Qxa4 Qxa4+ which is still winning (-4.9 at 31 ply) and going for the game continuation (-6.7 at 33 ply). For memo Ivan Cheparinov did well until he faced Carlsen in quarterfinals (who lost in semi to Kamsky who eventually won the cup).

Mar-17-24		scormus: I was OK the first few moves (26 ... Bxa3 came into the centre of my radar screen mainly because it was a puzzle). I confess to rushing into 30 ... Rxa4+?! without thinking. <Teyss> completely agree with all you say. Credit to both players - relentless pressure from B to win, and stubborn defence from W to stay in the game so long.

Mar-17-24		chrisowen: Ent its oy its q glad x Bxa3 abridge lit aoh its jah its a fig pug eg Bxa3 co

Mar-17-24		Allderdice83: The coup de grace, of course, is 40...d1=N!! Of course, if 40... d1=Q?, White escapes with a draw via perpetual check. After 40...d1=N+, whatever White does, Black will stop the checks to reach a won endgame.

Mar-17-24		alshatranji: <Was that really the swiftest way to a win for Chepa... or was he trying sadistically to prolong the torture?> Promotion to a queen would lead to draw by perpetual check: 41.Qe7+ Kg8 42.Qe8+ Kg7, or 41. Qe7+ Kh6 42. Qg5+, 43. Qg7, etc.
