Subject: Sicilian Dragon: Nunn's Opening Ref: Analysis
|
Dear Friends, I am using John Nunn's openings guide to study openings, and my choice is the Sicilian Dragon. I am unable to see the logic in a particular variation suggested (this is on page 219 for those who have the text). The list of opening moves is as follows: 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 The suggested variation is the first on the table on p. 219: It is as follows: 6. Bg5 Bg7 7. Bb5+ Bd7 8. Qe2 a6 9. Bxd7 Nbxd7 10. 0-0-0 Rc8 11. f4 Rxc3!? 13 bxc3 Qc7 13 Rhe1 h6 14 Rhe1 0-0 I am unclear about the 13th move and onwards. After 13...Qc7, Black attacks the c3 pawn, White does not protect the pawn in the above line, and Black, instead of capturing the pawn, plays h6. What is the reasoning to avoid defending the c3 pawn (for White) and capturing the c3 pawn (for Black)? Good luck, Mr. Balu

What is the > reasoning to avoid defending the c3 pawn (for White) and capturing the > c3 pawn (for Black)? I'm assuming you meant 14.Bh4 for white in the above line. If you meant something else, please correct me. My initial reaction is that, as a matter of principle, black is very undeveloped, and that pawn grabbing is a violation of general principles. Secondly, note that while it looks like while white can defend the pawn, at least in the short term (13. Rd3 0-0 14.Kb1 Rc8) black has a lot of pieces which can attack that square: the Nf6 can eventually go to d5 or e4, the Bg7 exerts latent pressure along the diagonal, the queen, the rook, heck, even the d7-N can go to c5 and then a4. Meanwhile white's dark-squared bishop is badly placed to defend the pawn, and linning up rooks on the third rank makes them, potentially, clumsy defenders if black shifts targets. So, basically, black can win the pawn later, if he wants, so white shouldn't tie himself up in knots to prevent it. So what if black grabs the pawn? Is this a strong move? Well, after 13. ... Qb3 14.Nb3 (stopping Qa1+) 0-0 15. e5 we reach a pretty critical position. Honestly, this sort of highly tactical position with unbalanced material is very hard to evaluate. White's kind is slightly exposed, but he has a strong control of the center and, of course, an extra exchange. I tinkered around playing this position against my computer and did pretty well as white - it's hard for black to avoid some key exchanges, and the white rooks come alive - but my opinion shouldn't be regarded as definitive. Nevertheless, it may make some sense for black to delay this capture until he has stronger followup moves. In the dragon, it's rarely wise to grab material if it costs you the initiative. -Ron
