HgMan-Willempie have started their game discussing the Advanced Caro:
http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1151070318 I'd be interested in, and will try to contribute to, a similar game in any of the following lines:
Sicilian Sveshnikov (any 9.Bxf6 or 9.Nd5 line, but earlier deviations (e.g. 7.Nd5) are also interesting)
Sicilian Najdorf/Scheveningen lines with Bc4
Yugoslav Dragon (with 9.0-0-0)
Ruy Lopez, Marshall Attack (the 15.Qf3 line mentioned by Smyslov_Fan looks interesting)
http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1150397393 Ruy Lopez, Zaitsev Variation
Modern Benoni (especially Taimanov/Flick Knife line, but others are also interesting)
Scandanavian Icelandic Gambit (this one might be too marginal to generate sufficient interest, though).
Semi-Slav Moscow or Botvinnik Variation
The Veresov Attack (this one also might be too marginal to generate sufficient interest)
