Nunn et. al. (1999)
Nunn's Chess OpeningsSince Lane quoted a Nunn game (two, actually; also Nunn - Spassky, London 1982), I was curious what NCO would offer. 4...h6 is covered on page 315, line 1. I was a little disappointed to not see any game references, but I do recognize some of the games.
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 Note 1: 4.Nc3; and 4.O-O, not relevant.
4...h6 5.O-O d6 6.c3 g6 Note 2: 6...g5 follows Gelfand - Bareev, Munich 1992 (+=), mentioned in Beliavsky / Mikhalchishin.
7.d4 Note 3: 7.Re1 with various lines. One of the games is Yudasin - Mikhalchishin, Lviv 1983 (+=), mentioned in Beliavsky / Mikhalchishin.
7...Qe7 8.Nbd2 Bg7 9.Re1 O-O 10.h3 Nh7 Note 4: 10...Bd7 follows Nunn - Christiansen, London 1982 (+=) mentioned in Lane;
and 10...Kh7 follows Psahkis - Nei, Tallinn 1983 (+=) mentioned in both Lane and Beliavsky / Mikhalchishin.
11.Nf1 Ng5 12.N1h2 Nxf3+ (+=) note 5: continues from line 1, 13.Nxf3 Kh7 14.a4 f5 15.dxe5 dxe5 (so far Ghinda - Beliavsky, Lvov 1981
https://www.sachista.sk/archivegames/game/21861), mentioned in both Lane and Beliavsky / Mikhalchihsin. Now NCO deviates with 16.Bd5 (+=). Beliavsky / Mikhalchishin also gave 16.Bd5 without evaluation.
