Which do you prefer between e4 and d4?


If I have White, it actually depends on my mood. I can do Ruy Lopez, or Queen's Gambit, and I'm thinking of starting to do KIA just for variety.

D4, because there's less options for black. It's generally more positional, but there are some agressive D4 openings, like Blackmar-Diemer gambit and Jobava London.
