against the f7-pawn is very awkward<br />

seek cover for his king on the queenside,<br />
but this turns out to be premature<br />
and should have been prefaced by the<br />

Otherwise:<br />
a) 11 "c2 transposes to Line D,<br />
note 'd2' to White's 10th move.<br />

the idea being that l1...exdS 12<br />

by 14 i.xc4! dxc41S ':e1+. However,<br />
