initiative as the dark-squared bishop<br />

Bellon-Abreu, Havana 1998. <strong>The</strong> invasion<br />
of the 7th rank makes ideas<br />
with f4 followed by a sacrifice on e7<br />
very relevant, while Black, with his<br />
badly coordinated pieces, has no interest<br />
in leaving White in complete control<br />
after a queen exchange.<br />
c14) 14 O-O! l:g8 (this pseudoattacking<br />
move is mostly a defensive<br />
move since White was planning 15<br />
i.h5, which, with White safer king's<br />
position, was about to become a real<br />
threat) 15 i.f3 i.xf3 16 tZ:lxf3 cxd4<br />
