Q+A for beginners(and everyone else)

You ask questions, I give answers

Question:  In chess books and magazines I read about weakness on the dark squares or light squares.  What do they mean by these weaknesses?  And why does it matter?

In some middle game position, I can't find a good move. Is my startegy of playing a "waiting move" acceptable? I simply move my king.

@MagnutsCarleson Would you answer for OP while he is away?

While beginners aren't posting. Which black gambit is sound? Latvian or Elephant gambit?

Elephant Gambit 1. e4 e5 2. Nf3 d5

Latvian Gambit 1. e4 e5 2. Nf3 f5

This isn't a beginner question. Which would you prefer to play as black? Ruy Lopez Marshall Gambit or Benko Gambit and why?

Why are beginners shy? Which system or opening benefits beginners most? Colle System, Kings Indian Attack, or Nimzo-Larsen Attack. Beginners are advised to play minimum openings repertoire.

I don't like randomly sacrificing my pieces or any strong attacks, then what opening is the best for me, and how should I improve?

I'll play Giuoco Piano first. That's the most familiar.

I somehow always lose when I play QGD, so I don't play it often anymore.

I am also not quite familiar with Nimzo-Indian, even though it's a good opening.

How to avoid blunders?

Ain't Beginners must learn Open games first? Why are Italian and Spanish openings popular? Why not taught or learned Scotch opening?

Sit on your hands. Seriously. That tip added 100 points to my rating.

If you are not a beginner, why repeatedly post questions here?
