on such a peculiar rook move may<br />
seem like a luxury, but 1O ... l:r.a7!? is<br />
actually not so stupid. <strong>The</strong> main idea<br />
is that it seeks to discourage 11 d5 in<br />
view of 11 ... l:r.d7, and the simple presence<br />
of a rook on the d-file limits<br />
White's options substantially. <strong>The</strong> development<br />
of the minor pieces can<br />
wait, for it is often quite handy to have<br />
the bishop defending e6. Also, if everything<br />
goes Black's way, it may<br />
even be possible to play ... c5, and then<br />
develop the knight actively on c6.<br />
Other options:<br />

14 ttJb6 l:r.a7 15 d5 is actually not very<br />
clear. If Black just had time to kick the<br />
knight away from b6 with ... ttJd7 everything<br />
would be in order, but it is not<br />
that easy; in Stone-Nogly, Hamburg<br />

and soon succumbed to the attack:<br />
