(a) 5 Ng5 is the Allgainer Gambit. After 5 ..... h6 6 Nxf7 Kxf7 7 Bc4+ (if 7 d4 f3 forces White to play 8 Bc4+ anyway) 7..... d5 8 Bxd5+ Kg7 9 d4 f3 10 gxf3 Nf6 Black is better.
(b) If 6 Nxg4 d5 7 d4 dxe4 8 Bxf4 Qxd4 Bxd4 =
(c) 7 Nxf7, played in Pillsbury-marco, Vienna 1903 is speculative, 7 Nc4 Nf6 8 Bxf4 Nbd2 bf6 was good for Black in Hebden-Hawksworth, London 1985.
(d) Other moves at this point - 5.....d5, 5.....Qe7, 5.....h5, 5.....Nc6, and 5.....d6 all give White the advantage.
(e)
8.....Bgh7 9 c3 (Spassky-Fisher, Mar Del Plata 1960, saw 9 Nc3 Nxc3 10
bxc3 c5 =+) 9.....0-0
10 Nd2 Re8 11 Nxe4+ is approximately
even.
(f) 9 Be2, suggested by Korchnoi and Zak, is possible.
(g) After 12 Qxe7+ Kxe7 13 Kxd2 White has enought for the pawn (Keres).
(h) 8 0-0 is the Rice Gambit. After 8.....Bxe5 9 Re1 Qe7 10 c3 Nh5 play becomes wild and messy, but it tends to favor Black.
(i) 8.....Nh5 (Staunton) 9 0-0 Qxh4 10 Qe1 Qxe1 11 Rx31 0-0 =
(j) Not 9 Bxf4 Nh5 10 g3 f6 11 Nd3 Nxg3 - +, Pillsbury - Chigorin, Vienna 1903
(k) Better than 11.....Re8 recommended by Bilguer, black has the advantage.
(l) (A) 7 Qd3 Nc6 8 hxg5 hxg5 9 Rxh8 Bxh8 10 e5 Bg7 11 Qh7 Kf8 is bad for White, Anderssen-Neumann, Berlin 1865 (B) 7 c3 Nc6 8 Qb3 Qe7 9 0-0 Nf6 also favors Black.
(m) 9.....Nc6 is worth a try.
(n) White has attacking chances for his lost material.. Play is sharp and probably balanced but this type of position is what King's Gambit players strive for.
(o) 6 g3 is interesting. On 6.....Nc6, the risky 7 gxf4 has been played (insted of transposing to the column iwth 7 0-0), but after 7.....g4 8 Ng1 Qh4+ 9 Kf1 Nf6 Black achieves an advantage.
(p) 8 gxf4 g4 9 d5, Arnason-Larsen, Reykjavik 1978.
(q) After 8.....Bh3 9 gxf4 Bxf1 10 Qxf1 White has value for the exchange due to his strong center and initiative.
(r) 12 exf5 0-0, Heuer-Villard, Tallinn 1964. Black stands well.
(s) 5 Ne5, the Salvio Gambit, was favored at on time by Steinitz. After 5.....Qh4+ 6 Kf1 Nc6 7 Nxf7 Bc5 8 Qe1 g3 9 Nxh8 Bf2 Black has a terrific attack. Other entertaining but dubious tries are 5 Bxf7+ (Lolli Gambit), 5 Nc3 (McDonnell Gambit), and 5 d4 (Ghulam Kassim Gambit).
(t) 12 Nd5 Kd8 13 Qe2 Qe6 14 Qf2 Qf5 used to be thought a forced draw, but Black plays 13.....b5 14 Nxe7 Qc5+ 15 Rf2 Nxe7 and obtains the advantage.
