I graduated 30 years ago. The problem isn't grammar but too little informatin in your questions. Ideas and pitfalls on the QGD depend on the variation you play and which color you are playing. The QGD is a very large scope. It used to be the standard opening much as the Sicilian is today.
Black tends to a solid structure, the QB is sometimes a problem and winning chances are diminished. White has a hard time breaking in and often loses the thread since few black players play the QGD. The QG is sometimes called a point machine but that is somewhat overstated. The QGD has declined because there are fewer winning chances for Black in comparison to say, the Indian defenses. Remember, however, that increased winning chances usually means increased losing chances as well.
how effective is this opening?
