I was watching Lichess TV the other day and I saw a game between two IMs go something like this:
[FEN ""] 1.e4 e6 2.d4 d5 3.e5 Nc6 4.Nf3 f5 5.Bd3 Nh6 6.O-O Nf7
The computer evaluates this as something like +1.5 for White so it's technically unsound, but I think it still seems interesting. If White isn't careful it seems like Black can go for a kingside pawn storm and put White under lots of pressure, and the plans are completely different from the regular Advance French. Does this have any potential as a playable opening in shorter time controls?
