This brings out the knight immediately<br />
before it gets in danger of being<br />
trapped in the corner, and appears the<br />
most dangerous for Black. White has<br />
another promising option, viz. 14<br />

also slightly better for White, for<br />

l:tb8 21 liJd6+ ~f8 22 liJg6+ has been<br />
suggested as an improvement, and<br />

believes that Black is flne; after<br />

.lle3+ 25 'it>bl .txf4 26liJxa7, I think<br />
White keeps an advantage, because<br />
the knight is not in danger of being<br />
trapped, and if Black is not careful<br />
White may even be able to round up<br />
the d-pawn) 19 ... .lixc3 20 ~xc3 .tb7<br />

to draw, Razuvaev-Inkiov, Moscow<br />
