'iPc6 26 h4 eS and Black had some<br />
compensation, although it is not clear<br />
whether it is sufficient. For the moment<br />
Black is a pawn down but the<br />
f6-pawn is weak. Moreover, Black has<br />
a queenside majority and the more active<br />
pieces.<br />

Black should not be thinking along<br />
defensive lines, as the following examples<br />
show:<br />
a) 13 ... l:tc8? 14 i.e2 b4 (Black's<br />
previous move signals his intention to<br />
play ... cS, but it seems to be the wrong<br />
plan; here 14 ... cS is ill-advised due to<br />
