after 14.c3 Rf8 15.Nxh7 Rxf7 16.Ng5 Rf8 17.g3 Ne5 18.Bg2 Nhf7 19.Nxf7+ Rxf7 20.Qd4. Avrukh also considers 8...Ba5 9.Rb5 Bxd2+ (9...a6? 10.Rxa5 Nxa5 11.Nxc7+) 10.Qxd2 Kd8 11.Ng5 (the traditional reply 11.e4 may allow Black a playable game after 11...a6!? according to Bücker) 11...Nh6 12.f4!? a6 13.Rb3 Qxa2 14.Nc3 Qa1+ 15.Rb1 Qa5 16.e3 when Black is "close to losing", for example 16...Re8 17.Bc4 Nxe5 18.fxe5 Qxe5 19.Bxf7! Qxg5 20.Bxe8 Kxe8 21.Nd5 Qe5 22.0-0 and "White wins." Bücker also considers 9.e4!? to be a strong alternative to 9.Rb5, leading to a clear advantage for White. Black therefore sometimes tries 4...d6 instead, continuing 5.exd6 Qf6 6.Qc1 (or 6.e3, returning the pawn). White's other major try for advantage is 4.Nc3 Nxe5 5.e4, securing a lead in development and leaving Black's queen awkwardly placed on e7. Stefan Bücker recommends 5...Nf6 6.Bg5 c6 7.Nxe5 Qxe5 8.f4 Qe6, with a playable game but some advantage for White. Viktor Korchnoi won a in a 1978 simultaneous exhibition with 4.Nc3 Nxe5 5.Nd5 Nxf3+ 6.gxf3 Qd8 7.Qd4 d6 8.Bg5!, but according to Bücker Black gets a playable game with 8...f6 9.Bd2 c6 10.Nf4 Qb6. Blackburne–Hartlaub Gambit The Blackburne–Hartlaub Gambit, 2...d6, was Charlick's original idea to avoid the closed openings, aiming for compensation for a pawn after 3.exd6 Bxd6. A sample continuation is 4.Nf3 Nf6 5.Bg5 h6 6.Bh4, when White remains a pawn up with some advantage. White can also delay the immediate 3.exd6, playing 3.Nf3 first, when after 3...Bg4, 4.e4 Nd7 transposes into a gambit line of the Philidor Defence played by Blackburne. Black gets partial compensation for the pawn after 5.exd6 Bxd6 6.Be2 Ngf6 7.Nc3 Qe7. White obtains a large advantage, however, after 2...d6 3.Nf3 Bg4 4.Bg5 Qd7 5.exd6 Bxd6 6.Nbd2. Soller Gambit The Soller Gambit, 2...Nc6 3.Nf3 f6, was named after Karl Soller. The immediate 2...f6 is sometimes seen as well, when 3.Nf3 Nc6 transposes, but 3.e4! Nc6 4.Bc4 gives White a large advantage. In the Soller Gambit proper, International Master Gary Lane recommends 4.exf6 Nxf6 5.Bg5. In this line Black gets partial compensation via 5...h6!, e.g. 6.Bh4 Bc5 (or 6...g5 at once) 7.e3 g5 or 6.Bxf6 Qxf6 7.c3 Bc5, although White keeps some advantage. White can also return the pawn via 4.e4, securing the better chances. Then after 4...fxe5 5.Bc4, 5...Nf6 6.Ng5! leads to complications that are very good for White, but 5...d6 may be an improvement. Felbecker Gambit The Felbecker Gambit, 3...Bc5, usually followed by ...f6,
