What is the fastest way for a player to reach the stage where they are not opening with nonsense moves? Assuming a player knows the rules, are there any free, one-player simulations that will rapidly teach a single player on their own how to move beyond opening with nonsense moves.
The concept that caused me to stop making nonsense moves is control the center.

That meant moving out the d and e pawns, possibly with the c and f pawns, either abreast, or in support. More likely, I'd move a knight to c3 or f3 (c6 or f6 if Black), then a bishop or two. Castle as soon as possible, before undertaking activities on the wings.

That eliminated a lot of bad opening moves like b3, g3, and worse, a4 and h4.
