Really depends on preference. For more experienced players, go with 1. d4, as it opens the opportunity for some pretty intense games that a beginner might not do well in. (i.e. Queens Gambit Accepted, Colle System, London System, ect…). 1. e4 offers a more predictable and foundational approach to chess opening theory, which can be easier to understand if you’re new to chess.
Which is better e4 or d4?
