ChessBase 13 questions: game review routine and megadatabase

Hi, I just bought ChessBase, a few questions:

1. What is your routine when reviewing a game in ChessBase? I am slowly going through the game with a Kibtzer on and checking against my repertoire in a few points

2. How do you use the Mega Database? I try to check a few positions there, but I usually just find other games played in the same position without annotations, not very helpful. I thought I was buying a database with people making commentaries on all the 6MM games, but the comments seem to be sporadic and not easy to find.

Thanks!

Lol didn't you read? From that 6 million games only about 60,000 are annotated. If the game isn't annotated you user your brain and share your doubts on Chess.com, have fun with Chessbase, a great software product
