What are some beginner to advanced openings or variations I could use? I’ve played chess for some time now, but I’ve really started to get into it these past few months. The thing I need help on is openings. I know about the different ones, and even attempted one or two of them, but I either end up forgetting the opening, or having the opening completely backfire on me. So what I’m wondering is, is there any opening that’s simple to learn but effective?
It is hard to answer a repertoire question with little supporting information. On that basis, I would recommend 3 things:


Complete the quiz on chesspersonality.com. At the end you will receive recommendations on openings, for White and Black, based on your answers
To stick to one opening as White, and have 1 response as Black for 1. e4 and 1. d4. The other common opening moves, 1. c4 and 1. Nf3 are quite rare at a  beginner level, and are chosen because they usually transpose into 1. e4 or 1. d4 openings anyway
Look at some opening videos on YouTube, such as those by Dereque Kelley. If you like the look of an opening, try taking the main themes into your next game
