Black attempts to create counterplay<br />
by activating his bishop on the<br />
a6-fl diagonal but the move has the<br />
obvious drawback that it opens lines<br />
for White against Black's own king.<br />
However, the alternative 18 .. J~h5<br />
is not much better: 19 ltd4 c5 (or<br />

is given by Yermolinsky and Shabalov,<br />
and looks more ambitious. I would<br />
definitely prefer White. Black cannot<br />
hold the c5-pawn and creating counterplay<br />
with ... a5 requires some preparation.<br />
Meanwhile White has walked<br />
his h-pawn closer to promotion.<br />

It is important to note that if Black<br />
wishes to play the main line after 11<br />

than 15 d5, which transposes to Chapters<br />

ending according to Tal. This is<br />
one of those endings where, despite<br />
being a pawn up, White must take<br />
great care owing to Black's queenside<br />
pawns.<br />
