Is it a good idea to have an entire nother opening repritore for a person's blitz game's and another opening repritore for your regular chess.
When playing blitz, you need to be able to just fire moves out very quickly at the beginning of the game, so that you have more thinking time later on. For this reason, I feel that you should use the same repertoire for both games.
I use blitz to test new lines in my openings or even try new openings that I may switch to--but then again I do not play anything faster than 3 0
