You don't have to memorize any names, or openings, when learning chess.
Millowitsch or Gavronsky Defence ? Which is better ?

Ok, two things about this post: First, it most certainly does not belong under "Live Chess," I think it would be more fitting to be seen in a category like "General Chess Discussion." Secondly, you should create names for posts that reflect the nature of your question. I would suggest "Opening Names."
Now that I am finished with the critique, let me answer your question. To begin with, there is no law that says you must know the names of openings and famous players. However, if you do not, you will be ridiculed in the chess area. For example, it is much easier to go into a bookstore and ask for a book about the Najdorf Poisoned Pawn Variation than to set up a board (1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb6 Qd2) with and ask "Got any books about this?" In short, opening names simply are just for communication among chess players. They are not at all hard to learn, so why not take 30 minutes one day and knock all of the important ones out at once?
As for player names, yes, you should know them. You don't necessarily have to be able to connect Kramnik or Tal to their pictures, but you should know that Kramnik plays like a brick wall (extremely solid) while Tal was thought of as a tactical Magician. This will help when looking for games to study. Of course, as usual, it's not that hard to learn, and you will acquire more knowledge as you learn more about chess.

Thanks Chassis. I get your point (to a point). People trying to improve, and I consider myself a novice, get confronted in chess videos and tutorials with all sorts of strategies, tactics, moves and counter-moves and these are all tied to and named after their inventors. Basically, when confronted with the Millowitsch attack, the Gavronsky moves will solve it. I am not interested in both innovators' names. I for one, and guaranteed many others, get even more confused when confronted with a barricade of names and we are seeking something simpler to get better.
I guess I had all the master excited now. Is there a Millowitsch or Gavronsky ? Frankly, I don't know and I don't care. All I know is that I love the game of chess, the way you get absorbed into the game, you become the game, time and space disappears etc etc. You know what I am talking about. Is there not an easier method to improve your chess without having to be memorise names like Lasker, Italian, Sicilian, Greek, Mayan or Peruvian openings or moves ?
