21 axb5 cxb5 22llJxf7 .i.xg2<br />
23 ~xg2 llJc5 is unclear. <strong>The</strong> black<br />
pawns are extremely dangerous and<br />
for the moment a lot closer to their<br />
goal than White's kingside phalanx.<br />

even further.<br />

Other options are:<br />

13 g3 nxd4 14 .i.xd4 'ii'xd4 would<br />
perhaps be just about OK if White<br />
were forced to exchange queens, but<br />
15 'ii'e2! is strong, and after 15 ... llJd7<br />

Sch6n-Polajzer, Biel 1990.<br />
d) 12 ... e5!? was for a while my<br />
best attempt to resurrect this line for<br />
Black. If Black could exchange the e<br />
pawn for White's d-pawn he would<br />
have a strong queens ide majority, and<br />
the outcome would basically be very<br />
unclear. Another factor is that Black's<br />
bishops are stronger than their white<br />
counterparts and exert pressure against<br />
White's queenside. <strong>The</strong>refore White<br />
must play 13 d5 .i.b7 (13 ... cxd5 14<br />
