Best chess opening?
The article in post #2 seems very generic and offers little useful information. How are the Sicilian, French, Slav, and even the Ruy Lopez are good for beginners when I have heard master level players and experienced coaches say these are precisely NOT what a beginner should play (though there is mixed advice on whether a beginner should play the Ruy Lopez)?
So pick an opening—any opening—and stick with and study it. You won’t get better just because you picked a different opening that is “better.”
