(a) 5 c3 transposes to column 5.
(b) On 5.. . Nxe4 6 Qe2 NxeS 7 Qxe4 Qe7 8 d4 Nc6 White can play a slightly better ending with 9 Qxe7t Bxe7 10 c3 or the complicated 9 Qg4 h5 10 Qxg7 Bxd4 ~.
(c) A better try is 7 Ba4 Nxe4 8 Qe2
Be7 9 Qxe4 Ng6 10 c4 (10 f4 0—0 11 f5 d5 12 Qd3 Nh4
13 g3 c5 14 dxc5 HxcS± 15 Khi
Qa5 o~, Zapata—Torre, Thessaloniki 1988) 10 ... 0—0 11
Nc3 d6 12 Nd5 with a small edge, de
Firmian—Fishbein, New York 1989. The column is
Chandler—Spassky, London 1984.
(d) Amusing is 6 dxe5 NxbS 7 a4 winning hack the knight. After 7 ... Nbd4 8 Nxd4 Nxd4 9 Qxd4 d5 Black is equal, Suetin—Bannik, Vladimir 1960.
(e) Bisguier has often played 7 ... Ne4, yet Gulko—Reshevsky, Vilnius 1978, continued 8 Qe2 Nc5 (8 ... Bf5 9 Rdl Qc8 10 Rd4!, Lohron—Lombardy, New York 1987) 9 Be3 Bg4 10 Nc3 Qe7 11 Rfel with an edge for White.
(f) Also giving White a slightly better ending is 9 Nc3 Ke8 10 Ne2 Be6 11 Nf4 Bd5 12 Nxd5, Fischer—Bisguier, US Chp. 1963.
(g) 12 Ne2 Bd5 13 Nd2 c5 14 Nf4 ±, Tseshkovsky—Romanishin, USSR Chp. 1976.
(h) 8... Nf5 9 Qe4 g6 10 h3 0—0 11 Bh2 Bb7 12 Nhd2 is better for White, Morovi&-Spassky, New York 1987.
(i) Another good plan is 9 Nc3 0—0 10 Ret Nc5 11 Nd4 Ne6 12 Be3.
(j) 12 Bg3 f5 13 exf6 Bxf6 14 c3 Be7 15 Radl gives White more fii~epower in the center, de Firmian—Kne~evit~, Reykjavik 1984.
(k) 5 ... Nf6 6 NxeS Be7?! (6. . . Nxe5 ±) 7 d4 0—0 8 Nc3 leaves Black in a bind, MUller— Behting, Riga 1899.
(I) Also reasonable is 6 . . . Nxe5 7 Rxe5t Be7. The column is Sherwin—Bisguier, US Chp. 1962.
(M) 4 .. . d6 allows 5 d4 exd4 6 e5!
dxe5 7 Nxe5 with some advantage, A. Ivanov—
Roinanishin, USSR Chp. 1980. 4
(n) It is probably better to play 6 d4 exd4 7 cxd4 d5 8 e5 Ne4 9 0—0.
(o) In Kupreichik—Levin, Kiev 1976, Black achieved equality with 6... dxc6 7 NxeS Bd6 8 d4 c5 9 0-0 Re8 10 14 cxd4 11 cxd4 c5.
(p) 12 c4 ds 13 Nc3 dxe4 14 dxe4 Qd4t, Dzindzichashvili—Shamkovich, New York 1983. 6 Black is better.
(q) In the last century 4 d3 was commonly
seen. This is playable, of course, but it does not 7 set Black any problems.
4 . .. d6 5 c3 and either 5 .. . Be7 or 5 .. . g6! Gives Black an
equal game.
(r) 4 . . . Nxe4 5 0—0 transposes to
4 0—0 Nxe4 5 d4 (col. 2).
(s) 7 Ba4 transposes to col. 106. Column
12 is Kuindzi—Tseitlin, USSR 1977.
