I agree with Bubba73 and Quale argument when they point out that the opening is not covered in any of the comprehensive opening encyclopedias such as ECO. The "C01" code arises out of 1.e4 e6 2.d4, not 2...f5. ECO covers a fair share of relatively obscure lines with a line of analysis or at least a footnote, so lack of coverage there is quite telling. I will also add that the move appears to be very seldomly played, the 365chess database list only 23 games http://www.365chess.com/opening.php?m=4&n=12&ms=e4.e6.d4&ns=3.16.12 (40 games if we include the transposition via the Staunton Gambit: 1.d4 f5 2.e4 e6), and while the earliest entry there is a game by Mikhail Chigorin, a single use by a top player is not sufficient basis for an article. The sources are self-published and the analysis seems to be done by amateurs, thus there is a |reliability problem
