31 ( +1 | -1 ) from nunn's chess openings:"this combative line leads to highly unbalanced positions in which Black accepts serious structural weaknesses in return for active piece play and a potentially powerful pawn center" i hope this is helpful... i have noticed too that this is a popular line here.
24 ( +1 | -1 ) Sveshnikovtheory runs 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5 9. Bxf6 (or 9. Nd5 Be7 10. Bxf6 Bxf6) gxf6 10. Nd5 f5, usually leading to a roughly equal position where Black's static weaknesses are counterbalanced by chances along the g-file, breaks in the center and active pieces.
25 ( +1 | -1 ) Chuck:1...e5 in nfp40uk's post is obviously a typo for c5: you know this by the fact that "a lot of people plays it", by the 3...cxd4 move and, especially, by the 5...e5 move, quite impossible in a Scotch :)
