Kolevs simple solution is very interesting:
"The so-called Positional variation
against the Sveshnikov has become
lately the first choice of White
players of all levels. A quick check
in my database shows that in
2006-2008 it occurred two times
more often than the lines with 9
¥xf6. Apparently fashion, but also
fear of the sharper variations, have
a strong impact on White’s preferences.
Otherwise it is difficult to explain
this fondness of a line which is
too well explored, aspires to a small
positional edge at best, and is often
rather boring . Of course Anand
or Shirov may have every reason to
like it, provided it brings them full
points sometimes, but they have super
technique and deep analyses of
the arising positions and even endgames.
The lower the level, the worse
are White’s statistics.
Below 2400,
first players scored only about 50
percent in the last two years.Currently I do not see any
serious theoretical problems
for Black."
And he is right !!! The "Khalifman product" tells us: "Come on buy me and I tell you how to beat the Sveshnikov.........but only if you are able to memorize a lot of information....." (@Matemax: nice idea to give the books a voice

:-)) And if you are a fulltime-player...
Kolevs book tells us: "I only want to be a new repertoire-book about the Sveshnikov, buy me und hope to get a good game against the "normal" OTB-players .
