The term of "Game Explorer" is simply bumptious. There's nothing to be explored with talking of games/openings/lines etc. This more or less accidental cluster of moves is neither cohesive, nor explained and is completely antiquated. What's opening theory got to do with it? Less than nothing. It was - if ever - meant to help and assist players with very small knowledge of opening theory. RHP is not the cheapest among the private chess sites but to update features like the most important Game Explorer seems out of interest. One year of adherence will do, it doesn't make sense to stay here any longer.
