Jan-22-09  percyblakeney: <Considering how many wins, and relatively few losses Radjabov has in the KID, I don't see why he would even consider giving it up. It seems that whenever a player plays an opening that some see as slightly dubious like the Dragon or the KID, as soon as they lose a game with it, people start talking about them giving it up, no matter how well they score with it>

Radjabov has some amazing results with the KID, especially in Wijk. After losing the round 2 game in 2003 he scored +9 -0 =4 before this game (one loss listed as a KID on this site should be a Benoni). Going an undefeated +9 with black in 13 games against top level opposition is just to good to be true and something like this had to be waiting sooner or later.

Well played by van Wely, but also a strangely effortless win. After all he only followed the ChessBase recommendation from Radjabov's game against Ponomariov and had a winning position almost immediately. Radjabov should probably have played 21. ... Nxe6 even if the position gets very messy.

Jan-22-09  KingG: I think Radjabov is simply off form in this tournament. He has done nothing with the White pieces, and didn't really play very well against Ivanchuk either. Even if he had forgotten his analysis, he probably should have seen that 21...gxh4 was going to lead to a horrible position.
Jan-23-09  notyetagm: <Eyal: ... A couple of moves later, 28....Nf4 is simply answered by 29.Rxf4! (exf4 30.Qg6#).>

A great example of a <PIN AGAINST A SQUARE>.

Yes, <RYBKA 3> at http://www.chessok.com/broadcast/?k... says that 21 ... g5xh4?! is dubious, that 21 ... ♘d4xe6 is better, and gives a variation ending with an eval of <Rybka Aquarium (0:17.21)+0.07|d18>.

21. Qg3 gxh4 ?!
(21... Nxe6 was better 22. hxg5 Nxd5 23. cxd5 Nxg5 24. Be3 Rf7 25. b5 Qd7 26. Qh4 Kg8 27. Rb3 Raf8 28. Rc1 Rybka Aquarium (0:17.21)+0.07|d18)

  Eyal: Btw, in case of 26...cxd5, 27.Rg3+ Kf7 28.exd5 which I mentioned in my first post is good enough to win, but even more efficient is 27.exd5 Ng7 (27...Kf7 28.Rf1 transposes to the game) 28.Rg3 Qc7 (or Rf7) 29.Bg6 (not immediately 29.Rf1? e4) with the plan of Rf1/Rxf6/Qh7+/Qh8+/Qxg7+/Qxf6 against which there's really nothing Black can do.

Jun-15-15  KID Slayer: A nice model game of beating the KID like second nature. I especially like van Wely's sequence starting with 26.Re3.

  Penguincw: In honour of the first major chess tournament of the year starting today (Tata Steel) here's a win from a few years back by the man who has participated at every one of them - Loek van Wely.

Uh, I saw the exposed kingside, so knew 26.Re3 had to be the first move, and I got it. No sacrifice here.

Jan-16-16  stacase: 30. Bf6+ is what I would have done over the board.
Jan-16-16  ozu: Well, I got the first move..haha

  thegoodanarchist: When your king is "attacking" on move 29 it is most often a sad situation for your game.

Most likely you will be resigning soon!

  patzer2: On today's Saturday puzzle (26. ?), I was undecided between 26. Qg6+ and 26. Re3!

Unfortunately, I made the wrong choice with 26. Qg6+ Ng7 27. Ne3 which gives White a slight advantage but no clear win.

What I missed is that after 26. Re3! cxd5 27. exd5 (+7.07 @ 19 depth, Deep Fritz 15 ) White's attack is crushing.

Black's game starts to slip away after 21...gxh4 . Instead, 21...Nxe6 = (-0.05, @ 30 depth, Stockfish 251115) keeps it level.

Jan-16-16  Cheapo by the Dozen: I went with a simple sacrifice-free 27 Nxf6 win, the idea being the f-file pin. I don't see a defense for Black.

The tricky bit is that the pinning has to happen with the e3 rook; if the pin is established at f1 and Black interposes the knight at f4, White's attempt to win it with g3 can be stymied by a Black pin on the g-file. However, if the pin starts at f3, then White's king can run to f2 and beyond.

  morfishine: Nice win by White, looked like he was winning the whole way through and had a variety of winning methods to choose from at the end
Jan-16-16  dfcx: Black is about to take white knight, white can trade the knight or be a little more brave!

26.Re3 cxd5 27.exd5
Now the diagonal and file are both open.

A. 27... Ng7 28.Rg3
A1. 28...Qc7 29.Bf5 Rae8 30.Rf1 b6 31.Bg6 wins
A2. 28...Nf4 29.Rxf4 Ke7 ( 29...exf4 30.Qg6#) 30.Rf1 A3. 28...Nh5 29.Rxg7+ Nxg7 30.Qh7+ Kf7 31.Bg6+ Kf6

B. 27...Qc7 28.Rg3+ Ng7, same as A1

Refusing the knight is not much better.

26...Ng7 27.Rg3 There is nothing black can do now.

  kevin86: White puts increasing pressure on the king side.

  agb2002: White has a bishop for a knight.

Black threatens 26... cxd5.

The first idea that comes to mind is 26.Qg6+ but after 26... Ng7 27.Ne3 Qe8 Black seems to gain time to reorganize the defense.

Another idea is 26.Re3:

A) 26... cxd5 27.Rg3+ Kf7 28.exd5

A.1) 28... Qb6+ 29.c5 dxc5 30.dxe6+

A.1.a) 30... Kxe6 31.Bc4+

A,1.a.i) 31... Kd6 32.Rd1+ Ke7 (32... Kc6 33.b5+ Kc7 34.Qg7+ wins decisive material) 33.Rg7+ Ke8 34.Qg6+ Rf7 35.Qxf7#.

A.1.a.ii) 31... Kd7 32.Rd1+ Ke8 33.Rg7 followed by Qg6+ winning (33... cxb4+ 34.Kh1 and 34... Rh8 just loses the rook).

A.1.a.iii) 31... Ke7 32.Rg7+ wins.

A.1.b) 30... Ke7 31.Qg7+ Ke8 (31... Kxe6 32.Bc4+ Kd6 33.Rd1+ Kc6 34.b5+ wins the queen) 32.Bg6+ Kd8 33.Qxf8+ wins.

A.1.c) 30... Ke8 31.bxc5 (31.Qg7 c4+ 32.Kh1 cxd3) 31... Qxc5+ 32.Kh1 and White attacks with all four pieces. For example, 32... Ke7 33.Rg7+ Kxe6 34.Bf5+ Kxf5 35.Qh3+ Ke4 (else mate in two at most) 36.Qf3+ Kd4 37.Rd1+ Kc4 38.Qb3#.

A.2) 28... Nf4 29.Rg7+ Ke8 30.Bg6+ wins decisive material (30... Nxg6 31.Qxg6+ Rf7 32.Qxf7#).

A.3) 28... Rg8 29.dxe6+

A.3.a) 29... Kxe6 30.Rxg8 Qxg8 31.Be4 with several threats (Bd5+, Bxb7, Bd5-Qh3-Qe6, Rf1, etc.) looks good for White.

A.3.b) 29... Ke7 30.Rg7+ Rxg7 (30... Ke8 31.Qg6+ Kf8 32.Qf7#; 30... Kf8 31.Rd7+, etc.) 31.Qxg7+ Kxe6 (31... Ke8 32.Qf7#) 32.Rf1 e4 (32... Qf8 33.Bf5#) 33.Bxe4 wins an important pawn (33... Nxe4 34.Qf7+ Ke5 35.Qd5#; 33... Qb6+ 34.c5 wins).

A.3.c) 29... Ke8 30.Rxg8+ Nxg8 31.Qg6+ and 32.Qf7#.

B) 26... Ng7 27.Rg3

B.1) 27... Rf7 28.Rxg7+ Rxg7 29.Nxf6+ + - [B+N vs R] (29... Kf7 30.Rf1 with a winning attack).

B.2) 27... Nfe8 28.Ne3 and White improves the position while Black is worsening.

B.3) 27... Qd7 28.Nxf6+ wins.

Jan-16-16  Sniffles: 26. Looking at the entire board it struck me that bringing both rooks into play was much more powerful than being a knight down. Too little too late, Blacks king side defense crumbled and the only option was the king beating a hasty retreat.
Jan-17-16  CHESSTTCAMPS: In this middle-game attacking position, white has a bishop for a knight and material is otherwise even. The black king lacks pawn shelter, but black expects relief of pressure (given the threat of 26... cxd5) after 26.Nxf6+ Qxf6. Instead of being so obliging, white can trust his initiative and add an attacker with the rook lift.

26.Re3!

White threatens 27.Rg3+ Kf7 28.Qg6# and any capture at d5 greatly enhances the power of the bishop:

A.26... cxd5 27.Rg3+ Kf7 28.cxd5 Nf4 29.Rg7+ Ke8 30.Bb5+ Nd7 (Qxd7 31.Bxd7+ Nxd7 32.Qd6) 31.Qxd6 wins.

A.1 28... Nd4 29.Rg7+ Ke8 30.Qg6+ Rf7 31.Qxf7#

A.2 28... Rh8 29.dxe6+ Kxe6 30.Bc4+ Kd7 31.Qg7+ Kc8 (Qe7 32.Bb5+) 32.Rc1+ Kb8 33.Be6 wins.

B.26... Ng7 27.Rg3 Rf7 (Qd7 28.Nxf6+) 28.Rh3 Rf8 29.Nxf6+ Qxf6 30.Qh7+ Kf7 31.Rf1 Nf4 32.g3 looks convincing.

All I have time for...

Jan-17-16  CHESSTTCAMPS: Right idea, incomplete implementation. A much simpler win in line B is shown by <agb2002>.
