MCO:1 data:0
POLL: Do you like to use MCO'S or online Data bases?

Well, I have an MCO which I use. I don't have access to a database. If I had a database, I'd use it over my MCO. So, take your pick on that one.

Databases to follow variations, Fundamental Chess Openings and Chess Opening Essentials to understand why the moves are played. There are free databases on the web. I use 365chess.com and pony up an extra $10 a year for its' "premium" features.

I try both, but they never seem to have the moves my opponent plays. So then I switch to blueemu's method.
I tried to use NCO in the 90s, it's similar to MCO. nowadays that kind of book is really outdated.
Databases, books based on explanation and opening-specific books are better.

i guess you like databases better mco:1 data:1 TIE

Um, what's an MCO? I use ChessBase databases to keep all of my annotated losses in, but I've never heard of an MCO. Is it something that could help me? Thanks!

Modern Chess Openings, a veritable godsend to players in the 50's and 60's as it lists variation after variation of the openings, alas without explanation. It's still used by a few old timers (it is a portable database after all) and those who don't know that it has been superceded by explanatory opening books and, of course, databases.
@Slimreaper, who asked what MCO is.

MCO = the Modern Chess Openings book

Personally, I like and have used FCO = Fundamental Chess Openings which is a lot more explanatory/descriptive, but much less encyclopedic.
