Favorite Opening Play


There is nothing wrong with a favorite, but take care of obsession with one opening as it restricts your enjoyment and in up and coming players hinders their progress.
I prefer king-side openings from black or whites viewpoint and they are a little easier to play. Defending against d4 I find difficult, and often end up in a cramped position. The queens gambit in the hands of a strong player is very difficult to counter.
What is your favorite opening for white and black? and why?
