WHITE GAMBITS: 9 exf6!? 129<br />

B<br />

Bellon - Lu. Perez<br />

Havana Capablanca mem 1999<br />

By playing an early a4, White usually<br />

attempts to prevent Black from<br />

playing ... ttJd7, the idea being that it<br />

would leave Black's queenside too<br />

loose. Nevertheless, here Black can<br />

play:<br />

12 ... ttJd7! 13ltJxd7 ~xd7 14 i.f3<br />

a615 axb5<br />

White does not achieve anything by<br />

opening the a-file, so 15 0-0 might be<br />

better, although White's opening then<br />

appears far from convincing.<br />

Black is winning.<br />

Quick Summary<br />

In my opinion good antidotes to 9<br />

exf6 have been found, as in the majority<br />

of lines Black can easily neutralize<br />

White's initiative with a timely ... ltJd7.<br />

For example, after 10 ltJe5 'iVxf6, both<br />

11 g3 (Line A) and 11 ..te2 (Line B)<br />

are well met by l1...ltJd7. 11 a4 (Line<br />

C) is White's best try, to which Black<br />

has reacted in various ways. <strong>The</strong> provocative<br />

11...c5 (Line C 1) looks too<br />

ambitious, while 1l...i.b7 (Line C2)<br />

used to have a slightly bad reputation<br />

but is now fully rehabilitated in view<br />

of 12 ... ltJd7! in reply to 12 i.e2. This<br />

seems to be Black's very best approach,<br />

and hence the popular 11.. .h3 !?<br />

(Line C3) will only have real relevance<br />

in the event of something being<br />

found for White in Line C2.<br />

This is White's basic idea. His previous<br />

move vacated the e5-square,<br />

which is now accessible to the knight.<br />

This knight serves several purposes.<br />

Above all its main function is to make<br />

it hard for Black to develop smoothly<br />
