Any reference material on the Franco-Benoni defense? The Franco-Benoni defense is characterized by the black moves:
[fen &quot;&quot;]
[startply &quot;4&quot;]

1. e4 e6 2. d4 c5

The books I've read on the French defense contain none or very little information about this opening. Are there any &quot;authoritative&quot; or &quot;main line&quot; references or books that investigate this opening? Are any of you using this opening in your games? Where do you get your information from?
There is a book on the Franco-Benoni. (Using the alternative name &quot;Barcza-Larsen&quot;)
It's rather old (1991) but I would guess theory doesn't move that quickly in the Franco-Benoni. It's probably a good way to get started, but you might want to check the lines with an engine.
Edit: There is also a short article by Harding on chesscafe.com.
