| Jan-17-08 | | Shams: <<percyblakeney>Looking through Corus 2003 and 2007, it seems as if Radjabov has +7 -0 =3 in his last ten KID's (or KID-Benonis)> clearly, it's only a matter of time before the young iconoclast washes his hands of this flawed defense. |
|
| Jan-17-08 | | Avarus: This sort of benoni is easy to play for black. Yes, white is also quite solid but imo if black can play ..b5 without some concession, black has a good game. <Eyal>, I'm no expert but thought 20..Bxf1 was natural here, as it is somehow just in the way of ..b5. |
|
| Jan-17-08 | | Eyal: A nice point mentioned by Radja is that 22...Qd7 prepares to meet 23.Qf4 with 23...Be5 24.Qh4 Bd4+ 25.Bf2 Bg7 - "Then the queen is just useless on h4, and f5 and b5 are coming". |

| Jan-17-08 | | Ezzy: Eljanov,Pavel (2692) - Radjabov,Teimour (2735) [E70] Corus Chess 2008 Wijk aan Zee (5), 17.01.2008 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Bd3 0–0 6.Nge2 c5 7.d5 e6 8.Bg5< Eljanov tried an unfashionable move in the opening against Kramnik in the last round which didn't work out too well. Now he tries one against Radjabov. The only big name player to have played 8 Bg5 was Petrosian against Fischer in a blitz game in 1970, which Petrosian lost. He probably lost because it was Fischer he was playing, and not because of 8 Bg5 :-) Experts in an opening usually punish you for inferior moves though, and Radjabov is an expert with the Kings Indian This position is more of a Benoni, but Radjabov is probably an expert in that as well. Lets just say he’s an expert in everything J> 8...h6 9.Bf4 Ng4< New move. 9...exd5 and 9...e5 have been played before.> 10.Qd2 Na6 11.a3 Nc7 12.f3 Ne5 13.0–0 exd5 14.cxd5 Nxd3 15.Qxd3 b6 16.Qd2 Kh7 17.Ng3 Ba6 18.Rfe1 Re8 19.a4 Bc4 20.Nf1< Aiming for e3 - g4 so Radjabov doesn't allow that. .> 20...Bxf1 21.Rxf1 a6 22.Bg3 Qd7 23.Rae1 b5 24.f4?? <I am giving this move as a blunder because someone of Eljanov's rating should not be making moves like this. For any Grandmaster, the tactics that ensue should not be beyond their capabilities. It was an aweful move. This is the second time (the first was against Kramnik) that Eljanov has tried to simplify to an inferior ending. So the double question mark is for his naivety>. 24...b4 25.Nd1 f5 26.exf5 Qxf5 27.Ne3 Rxe3 28.Rxe3 Bd4 29.Bf2 Bxe3 30.Bxe3 Nxd5 31.Rd1 Re8 32.Bf2< Ok 24 f4 wasn't a blunder as blunders go, but this is, so I will not punctuate this with a ?? I will leave it on 24 f4?? [32.Qxd5 Qxd5 33.Rxd5 Rxe3 34.Rxd6 Rb3 35.Rd2 c4 Is obviously the way to go, but white still has to suffer the endgame pressure.] >32...Nxf4 33.Qxd6 <Blimey, it gets worse. >33...Qe4 0–1 <Radjabov says that white was relying on 34.Qd7+ Re7 35.Qg4 and missed 35...Ne2+> 0–1 So Radja roles on with his Kings. Indian stroke Benoni. It seems to be a bad day for calculating variations. Eljanov’s 24 f4?? Was just aweful. I know I keep ranting on about it, but I am an amateur chessplayer and I could even see that it wasn’t natural and had possibilities for disaster.. I couldn’t calculate everything, but on general principles the d5 pawn would end up seriously weak. It just wasn’t right to open up the center. Just a gut feeling. Eljanov should have had more than gut feeling, he is blessed with calculating ability, and it should be well within his grasp to see that it led to a mch inferior position for him. A horrible move.. What an amiable and friendly guy young Teimor is. Great sense of humour. I could become a big fan of Radjabov, he presents himself really well and has a nice karma about him. Yeah, I think I’m starting to become a Radjabov fan. |

| Jan-17-08 | | Eyal: <Ezzy: 32.Qxd5 Qxd5 33.Rxd5 Rxe3 34.Rxd6 Rb3 35.Rd2 c4 Is obviously the way to go> As was pointed out in a previous post, 34...Re2! is much stronger in this line, as White can't defend the b pawn and Black gets a pair of connected passed pawns. Perhaps White's best practical chances reside in the queen endgame reached by 32.Bxc5 dxc5 33.Qxd5 Re1+(!) 34.Kf2 Rxd1 35. Qxd1 Qxf4+ where Black is a pawn up but White retains the b pawn. |

Them pesky queen and pawn endgames are notoriously difficult to win, especially when the kings are vulnerable to repeated checks. Good line that 32 Bxc5. That would have kept 'em in the playing hall til the sun went down. |

| Jan-18-08 | | Ulhumbrus: An alternative to 26 exf5 is to remove a potential pin on White's N placed on the square e3 from the move..Bd4 by the move 26 Kh1. On 26 Kh1 fxe4 27 Ne3 Bd4 28 f5 the N has supported this advance in time, as on 28...Bxe3 the f5 pawn can take the g6 pawn with check. On 28...Bxe3 29 fxg6+ Kxg6 30 Qxe3 Black may stand badly. |
