(a) 6 Ng3 Bg4 7 0—0 (Geller) gives Black some trouble defending his advanced center.
(b) (A) An important alternative is 7 ... Qg5 8 Qe2 Nf 6 (8 . . . Qxg2 9 Qh5t) 9 f4! Qxf4 (9 Qh4± 10 g3 Qh3 11 Ne5± c6 12 Bc4 Bc5 13 d3 Ng4 14 Nf7!

(B) Dubious is 7 .. . bxc6?! 8 Bxc6~ Bd7 9 Qh5± Ke7 10 Qe5+ Be6 11 Bxa8 Qxa8 12 Qxc7t ±.
(c) 9... Bd7 10 Bxd7± Qxd7 11 Qh5t g6 12 Qe5f Kf7 13 NbS (13 Qxh8 Nf6) c6 14 Qd4 and White s two pawns are worth more than Black s activity and open lines.
(d) White is two pawns ahead, but he is only slightly better. White s backward d-pawn and Black s open lines ensure active play for Black.
(e) A good alternative is 6 Nxf6t Qxf6
7 Qe2 Be7! 8 Bxc6 dxc6 9 NxeS 0—0 10 0—0 Bd6 11 d4 c5 12 Be3 Be6 13 f4,

almost compensate for White s extra
pawn.

(r) Black cannot free his position
with 10 ... b5 because of 11 Nxb5! axb5 12 BxbS and 10 Bxc6(c)
