THE MAIN LINE: 7 e3 liJd7 8 ~d3 dxc4 193<br />
main virtue of the move is that it is directed<br />
against Black's ... cS advance,<br />
and in general occupying the c-file<br />
with the rook makes it less attractive<br />
for Black to move his b-pawn.<br />
11 ... 0-0<br />
This 'automatic' move is not necessarily<br />
best. I actually prefer 11...'ii'e7<br />
for the simple reason that it avoids<br />
Line B3. Also, Black might sometimes<br />
eschew castling for a more rapid<br />
development of the queenside. <strong>The</strong>re<br />
seems to be no clear way for White to<br />
take advantage of the slight amendment<br />
of the move-order. Here are a<br />
few examples:<br />
