I think the most interesting thing about competitive Scrabble is that it's not really about memorising dictionaries. Once you assume that everyone knows every playable word, the real distinction is in the tactics. There's elements of statistics to determine what your opponent is likely to have, whether to play offensively or defensively, etc. It's a very different game to "family" Scrabble, but we always had the etiquette rule that you should know the definition of a word you played. It isn't enough to know it's in the Scrabble dictionary.
