by the way, if you're looking for some funny lines in the sveshnikov, I pretty much like this one myself. I have to say it doesn't happen much, and I found it by mistake, but it's finally an interesting gambit (Fritz says it's equal).
it's in the Nd5 variation
you come quite naturally to this position:
Now the funny move for me is Be6:
the apparent problem is that white can play Nxdf6 Qxf6 Qxd6 and black is one pawn down.
but then, after Rc8 you threaten Rd8, and are getting clearly ahead in development.
and either the guy sees the trick (which he normally should do) and remove quickly his queen, in which case, you have a dynamic advantage, which I personnally find interesting, for the material;
(like this for instance)
or if he doesn't, you just more or less win. (like in this game).
