Paradoxially this simple variation was not mentioned in a huge article (about 5 or 6 pages) by the Kaissibermagazine.
Some facts: (i)
Kaissiber 5 (1998) covered 3...Nge7 on 5 pages, part of a longer article of 13 pages on 1.d4 e5. My book "Englund Gambit" had given 3...Nge7 4.Bf4 Ng6 5.Bg3 as a refutation of Nge7. I still believe that 4.Bf4 is plausible and maybe as good as 4.Nc3. You are right to say that White can do without analysis of 4.Bf4. But the text was also meant to give instructions for Black, and so the tactical mess 4.Bf4, which dominated Zilbermints' practice, could not be ignored.
(ii) According to you, "this simple variation [4.Nc3 ... 7.Qd2 ...9.Qc3 +-] was not mentioned" in my article. However, my article did have the following:
"4.Nc3 Ng6 (h6!?) 5.Bg5 Be7 6.Bxe7 Qxe7 7.Nd5 (1-0, 56) Bruch - Gerstel, Ludwigshafen 1985 (thematic tournament)." Close enough, I believe. I didn't like 4...Ng6 and suggested 4...h6!? instead.
(iii) My article mentioned that Lev Zilbermints preferred to play Nge7 in blitz, continuing: "3...Nge7 seems well suited at least for this kind of chess".
(iv) The next issue,
Kaissiber 6 (1998), reserved one page for two readers' reactions on 3...Nge7. Here Klaus Petri gave the tactical detail which you mention: 6...Qxe7 (on the same page 6...Ngxe7 was discussed)
7.Nd5 Qd8 8.Qd2 Ngxe5?? 9.Nxe5 Nxe5 10.Qc3 [+-]. Mr. Petri even analyzed my
4...h6!? to which he replied 5.a3 Ng6 6.Qd5 (now I'd say that 6...d6 gives Black a shade of compensation).
(v) More letters on the topic were published and discussed in
Kaissiber 10 (1999), p.24f. Two readers (Oganian, Babakhanov) tried to refute our earlier analyses. They recommended 8.Qd3. In my reply, I explained why
8.Qd2! was stronger: White has the additional threat of 9.Qg5, to exchange the queens - which gambit players fear more than hell. And I gave:
8.Qd2 h6 9.Qc3 0-0 10.0-0-0 Re8 11.h4 Ngxe5 12.Nxe5 Rxe5 13.f4 Re8 14.Rd3 Kh8 15.g4 +-, when h7-h6 becomes a fatal weakness! A modern computer likes 11.g4 even more.
(vi)
Kaissiber 11 (1999) published a letter by Lev Zilbermints, questioning the strength of
4.Nc3 h6 5.h4 (Oganian/Babakhanov).
(vii) In
Kaissiber 12 (1999) Bent Larsen wrote that his first reaction on 3...Nge7 had been positive, thinking soething like: "probably relatively best". But he continued that his enthusiasm faded away when he found 8.Qd2!. On the "emergency solution" (Larsen)
4...h6 Larsen recommended
5.Qd3 (and agreed with LDZ that 5.h4 Ng6 6.Qd5 Qe7 7.Qe4 Qb4 wasn't dangerous).
Kaissiber wasn't misleading its readers by neglecting 4.Nc3, as you apparently suggest. Nowhere else you'll find more on 4.Nc3. In issue 10 I wrote that 4.Nc3! was a refutation of 3...Nge7. Today I am not so sure. Take Larsen's
4.Nc3 h6 5.Qd3, for example:
5...Ng6 6.a3 Bc5 7.Nd5 0-0 8.Qc3 Be7 9.Be3 d6 10.exd6 cxd6, opening the c-file. Black's strategy is dubious, but not ridiculous.
