Hi,
In one of his development of the centre game he suggest :
1. e4 e5
2. d4 exd4
3. Qxd4 Nc6
4. Qe3 Nf6
5. Nc3 Be7
6. Bd2 d5
7. exd5 Nxd5
8. Nxd5 Qxd5
9. Ne2 Bg4
10. Nf4 Qd7
11. f3 O-O-O !
12. O-O-O Bf5
Why 11. ... O-O-O ! and why the blacks don't take the bishop ? Ok then they'd be uncastling but I think they could still win, couldn't they ?

12. fxg4 Bh4+
13. Kd1
13. g3? is the silliest move.
Anyway, thanks for answering.

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 ...

I admittedly looked at the line you gave only briefly, but I still think Bh4+ is the move being avoided. Rhe8 seems strong to me even in the face of Kd1.
Perhaps it's avoiding the threat of 12. ... Rhe8, a move even sooner. I guess I'll have to give it a closer look than I did.

Endgames, part 1: Rook against Bishop — A superb lesson from Magnus Carlsen in endgame technique. It's been a while since we looked at the endgame, so this week we begin a short series on this often neglected area with a terrific demonstration of endgame technique from the ever-improving chess world No 1 Magnus Carlsen. Although White has the advantage of rook against bishop, Black has an extra pawn and a solid position on the chess board. How did Carlsen make progress? RB I'm pretty sure the answer lies in g4. The question is whether to nudge the pawn forward immediately or whether some preparation is needed first, perhaps exchanging on d5 or advancing the king to e3. The only way is concrete calculation, so let's see what ...

i don't like the position for white if he takes the bishop, black has the bishop pinned already, can pin the knight and can pile on the pressure on the queen...
12. fxg4? Bh4+
13. Kd1 Bg5
14. h4 R(h)e8
15. Qd3 Bxf4
16. Bxf4 Qe6
other lines seem to play in black's favour too, so 11... 0-0-0 makes perfect sense to me, it's a clever move designed to entice white to take the bishop. and well done white for spotting the danger, and castling quickly.

Dortmund Begins — The Sparkassen Chess-Meeting (an odd name, to be sure) began Thursday in Dortmund. Though the chess tournament is not at the level of Linares or Corus, it still attracts top players, notably Vladimir Kramnik, the former world chess champion from Russia. Kramnik has been associated with Dortmund, as the chess event is often referred to, for many years because he has won the tournament nine times, far more than any other. He first won it in 1995 and is the defending champion this year. The tournament is a double-round robin this year, meaning each competitor plays all the others twice, once with each color. In addition to Kramnik, the No. 4 chess player in the world, the field includes ...

... L.M.Pickett (1976) gives this line, observing that 12.fxg4 "leads White into difficulty": 12 ...Bh4+ 13.Kd1 Rhe8 14.Qd3 Qxg4+ 15.Be2 Rxe2 16.Qxe2 Qxf4 17.Kc1 Nd4, which Paul Keres assessed as (+/-). It seems that 12...Rhe1 or 12...Bc5 are also likely to lead to a Black advantage. In view of the threatening stance Black can take up after 12.fxg4, it would appear best to be avoided - unless you want to exercise your defensive technique!

Zhao and Zatonskih Lead Chess Championships — Anna Zatonskih, the defending chess champion, took the lead of the U.S. Women’s Championship on Wednesday, while Parker Zhao, the ninth seed, solidified his grip on the U.S. Junior Championship. The two chess tournaments are being held concurrently at the Chess Club and Scholastic Center of Saint Louis. Zatonskih had shared the lead for the last few rounds with Irina Krush, the top seed. But in Round 5 on Wednesday, Zatonskih beat Iryna Zenyuk, while Krush only drew against Camilla Baginskaite. Zatonskih now leads with 4.5 points, while Krush and Tatev Abrahamyan, who beat Abby Marshall on Wednesday, have 4 each. In the junior championship, Zhao, who ...

Ok, but then why did white play 11. f3 ? It's a waste of time, they coud've (shoud've) move their light square bishop ?

A Chess Odyssey — One single square can make a big difference in a chess game. It helped me to launch one of my longest combinations against Anatoly Karpov in Caracas 40 years ago. It was a memorable chess tournament for both of us. Karpov arrived in Venezuela as the reigning world junior champion. He played well enough in Caracas to become the world's youngest chess grandmaster at that time, at age 19, and his brilliant career began to take shape. In 1971 in Moscow, he clinched the first major tournament victory, sharing first place with the three-time Soviet champion Leonid Stein at the prestigious Alekhine Memorial tournament. In 1975 he was crowned the world chess champion. This year ...

... and indeed Pickett passes it by without comment. Looking at the position, though, it is a difficult move to go past. It looks logical, to cut off the bishop's action along the white sqaures in White's field.
11.Be2 Nd4 looks rather unpleasant, inducing the bishop to move again: 12.Bd3.
Against any other bishop move, Black just develops normally with 12.0-0-0. An illustration of what a nuisance the g4-B can be is this horrible possibility: 11.Bc4!? 0-0-0 12.Bxf7?? Bc5! 13.Qxc5?? Qxd2+ 14.Kf1 Qd1+ 15.Rxd1 Rxd1#.
So, given the position at move 11, f2-f3 seems to be called for. After 11.f3 0-0-0 12.0-0-0 Black really does have to move the bishop. At liege in 1930 Frank Marshall tried to sac the thing by 12...Rhe8 against Sultan Khan, and got axed in 22 moves (13.fxg4 Bg5 14.Qf2 and already Marshall didn't have enough attack).
Having said all that, both sides have other options, especially Black at move 4 and White at move 6.
Cheers,
Ion

absolutely, but it is possible that white was unaware of the danger until black player 0-0-0, then he analysed and realised he wasted a move!
