At our level of play, your only important task in the opening is to reach a middle-game position in which you feel comfortable and confident. Whatever sequence of opening moves gets you there is the best opening for you.
Me? 1.e4. Or maybe 1. Nf3. But your mileage may vary.
This is a topic that is the most debated. Should you start with e4 or d4? I am a titled ACM player, but I don't know. Please share your opinions.
