In Playing 1.e4 e5 - A Classical Repertoire, where he recommends the Two Knights and the Breyer.

Interesting subject. Straggler, where did Ntirlis said that?

Many thanks to all. Ntirlis also recommends 4...Be7 and does not mention 4...h6. But he remarks on the resemblance between 4.d3 in the Two Knights and d3 in the Spanish, and against 5.d3 in the Spanish he does recommend 5...d6 and 6...g6. He even points out that this line can turn into an accelerated version of his Breyer lines with ...Be7-f8-g7. So, for someone who likes those Breyer lines, I'm wondering whether 4...h6 might actually be a way to take advantage of the bishop being on c4 rather than b5!

... the aforementioned 10...Nd7 ...

I didn't see 10...Nd7 anywhere.

Lane gives 10...Bd7 (10...Kh7, 10...Nh7, 10...Qd8).

Beliavsky / Mikhalchishin gives 10...Nh7 (10...Nh5, 10...Nd8, 10...Kh7).

Nunn gives 10...Nh7 (10...Bd7, 10...Kh7).

I think 7.d4! is correct, but black should also investigate slower moves because many whites will play 7.Re1 or other autopilot moves.

Incidentally that Nunn-Christiansen game appeared in Secrets of Grandmaster Play by Nunn and Griffiths (and the later edition, Secrets of Grandmaster Chess).

No, it's 4...Be7 there.

4...h6 is also not in:
  • Bologan (2014) Bologan's Black Weapons (4...Be7 and 4...Bc5).
  • Lokander (2015) The Open Games with Black (4...Be7).
  • Johnsen (2018) How to Beat the Open Games (4...Be7 and 4...Bc5).


Edited:
added Lokander

Delchev claims an edge for White in the line 4.d3 h6 5.0-0 d6 6.c3 g6 7.d4! Qe7 8.Re1 Bg7 9.Nbd2 0-0 10.h3 in his book "Bc4 Against the Open Games" (Chess Stars 2018), although he doesn't analyze the aforementioned 10...Nd7. I haven't checked his analysis for myself yet but in general, I think his work is of high quality.

In fact, the popularity of 6...g5 can be largely explained by the fact that it prevents 7.d4?! due to 7...g4. I'm not so sure about 6...g5 following other "non-critical" 6th moves, however...

Nunn et. al. (1999) Nunn's Chess Openings

Since 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.

Alexander Ipatov: Unconventional Approaches to Modern Chess
Volume 1; Thinkers Publishing 2019
covers an aggressive approach in this line:

Ipatov analyses two games (pages 309 - 315):
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 h6 5. 0-0 d6 6.Re1 g5
(Vachier Lagrave - Mamedyarov 2018)   and
... 6.c3 g5
(Fossan - Hammer 2018)

I am not sure if John Emms has covered 4.d3 h6 in
"Play the Open Games with Black".

Thanks very much. With your help I've also found a discussion of 5.0-0 d6 6.c3 g6 7.d4 Nd7!? (or "?!" according to Beliavsky & Mikhalchishin) at http://www.chesspub.com/cgi-bin/chess/YaBB.pl?num=1326725495/5. I'm not sure what that discussion is doing in the "Italian" sub-forum.

Lane (1993) Winning with the Bishop's Opening

Game on pages 41-45: Nunn - Christiansen, London 1982. Additionally four other game fragments (not counting one for 4...d6), including Ghinda - Beliavsky. The most recent quoted is Psakhis - Nei, Tallinn 1983. I suspect that Lane's analysis relies heavily on the Informator(s).

In Ghinda - Beliavsky, Lane offers a one-move improvement, 20.Ne4, saying it "gives white an acceptable game". Beliavsky / Mikhalchishin analyze 20.Ne4 to move 26.

Beliavsky / Mikhalchishin (1999) The Two Knights Defence

The book has some gaps...

4.d3 is not in the theoretical section, but is in the games section. 4...Be7 is games 10 and 12, and 4...h6 is game 11 on pages 39-42: Ghinda - Beliavsky, Lvov 1981. In the notes they reference 14 other game fragments, including two each by Beliavsky and Mikhalchishin, also including Kogan - Svidler (=). The most recent quoted is Tiviakov - Sermek, Beijing 1997.

4.d3 h6!?

I'm looking for material on the Two Knights with 4.d3 h6!?, intending a quick ...g6. Apart from a handful of games in the CP archive, I'm only aware of one game (Kogan - Svidler, Oakham 1992) in Pinski's book, and brief clips on Mikhalchishin's DVD for Black and Bologan's for White. Does anyone know of anything more substantial?

There's also a piece by Kuzmin in ChessBase Magazine 187, but that's on plans with ...g5!?
