It depends what you consider plausible, which in turn depends on the level of your opponents. Lane covers 3...exf4 (eight games) and 3...Bc5 (one game) in chapter 7. That seems about right. If weaker moves than that are plausible, Lane's book is more than good enough for your needs. After 3...exf4 Lane is covering three white systems: Hamppe-Allgaier Gambit 4.Nf3 g5 5.h4 (two games), Pierce Gambit 4.Nf3 g5 5.d4 (five games), and Steinitz Gambit 4.d4 (one game).

Lane doesn't consider 5...Nge7 at all.

If you are considering getting Lane, and are really keen on the Vienna Game, then perhaps you will be interested in the Fritztrainer CD: Gregory Huber (2005) The Vienna Game. It's not a book, but since you don't seem to care about the "recent" requirement, maybe you also don't care about the "book" requirement.

This is my last post on Gary Lane's book. If @grandpatzer has any more questions about it, someone else will have to answer.

Yes, Lane covers this, chapter 7, nine games, 14 pages. His words are encouraging for white, but his moves are not.

This is covered from the Black side in my book

AfaI there isn't any. I don't think there is any need either. the Steinitz Gambit (3...exf4 4.d4), the Hamppe-Allgaier Gambit (3...exf4 4.Nf3 g5 5.h4) and the Pierce Gambit (3...exf4 4.Nf3 g5 5.d4) are dubious at best. The modern 3...exf4 4.Nf3 g5 5.g3 was investigated by GM Shaw in his 2011 book via 2.f4 exf4 3.Nf3 g5 4.Nc3 Nc6 5.g3 and d6 6.d4 Bg7 7.d5 Ne5 has been tested in several corr. games and is equal.
There are no new developments in the KG Declined with 3...Bc5 4.Nf3 d6 5.Bb5 (5.Bc4 Bg4 6.Na4 exf4) Nge7 either.

Is there a good (fairly recent) book about the Gambit line 1.e4 e5 2.Nc3 Nc6 3.f4? I suppose that the "Modern Vienna" by Ovetchkin and Soloviov (Chess Stars) goes with 3.Bc4 only, or is there coverage of this, too?
