38 ( +1 | -1 ) Sicillian Dragon, Yugoslav attack question?After 1.e4 c5 2.Nf3 d6 3. d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 0-0 I'd like to play 8...Bd7 9...Nc6 instead of the usual 8....Nc6 9..Bd7.
My reason is I prefer having an half open c file to an half open b file the latter occurs when white plays Nxc6. My using 8...Bd7 I can recapture with my bishop instead of my b pawn. Is there any reprocushions for black playing .Bd7 before Nc6? Or does it not matter?
40 ( +1 | -1 ) Finebut a) White can now play 9. 0-0-0 without first playing 9. Bc4 and not worrying about 9. 0-0-0 d5 (which limits Black's counterplay since there's no exposed c4-Bishop to attack), and b) a half-open b-file is almost always better in the Sicilian, especially in the Dragon, due to the extra central control and the better coordination with the bishop on g7, in addition to more attacking prospects against a queenside castled king.
60 ( +1 | -1 ) 8. Qd2 Bd7Atrifix is correct that ...b7xc6 is usually better than ...Bd7xc6. When the b-file is open, Black will have the possibility of playing ...Rb8 and ...Rxb2. After 8.Qd2 Bd7 9. O-O-O, Black should play 9...Nc6 which transposes to a playable line (at least as far as I know, since the theory of this line has changed a lot in the last few years). If Black castles and plays Nc6-e5-c4, White will be ahead 2 tempi with Bf1xc4 instead of Bf1-c4-b3 and Bb3xc4. White can also get an advantage after 8.Qd2 Bd7 9. Bh6!, and exchanging the bishops. Bh6 is not possible after 8...Nc6 because Black would win with 9...Bxh6 10. Qxh6 Nxd4.
31 ( +1 | -1 ) AFAIKthe line is playable, but white doesn't have to be concerned with the 9. 0-0-0 d5!? lines. I'm not sure that 9. Bh6 actually gives White an advantage (it does exchange the bishops, but this is not always good)--I'd have to look at it more extensively. Black can also avoid the 9. Bh6 line by playing 7... Bd7 8. Qd2 Nc6 and then 9... 0-0, if he wants to.
