I play the French to demonstrate that 1 e4 is premature - Aaron Nimzovich.
This opponent ended up being flagged for assistance, but I didn't find the game boring. Maybe you agree?
en.lichess.org/Zt6GlneEQZcTI only play the French as black against e4, and I have very few boring games in the opening (I am a low ranked player.) It's a slow buildup opening, asking your opponent to make the first move. It can lead to tense scenarios, depending on the match-up.
