Sorry Pacifique but the move 2. e5 is terrible as not only does it allow Black to equalize on the 2nd move it even gives Black an advantage.
Now there are even worse moves such as 2. Ba6 which loses immediately.
but in the realm of what many players view as normal moves--2. e5 is the worse.
I will agree that after 1. e4 d5 2. e5 c5 3. b3 is a reasonable attempt to repair the damage.
@Turm_Breuberg - I think ...d4, perhaps as soon as move 4, is the way to play against that system.
