Anyone familiar with the following title?
Coles Notes: Your Guide to Better Chess, by Roger Langen (2002).
Subtitle: For intermediate players: Openings, gambits, codes, midgame
tactics, endgame strategy.

I'm a beginner (class D player) who recently recieved this book as a
gift. It seems pretty good, but I couldn't find any information about
it on the internet. Just wondering if others are familiar with this
title, and can give any comments about it.

My impression is that it is very concise, but nonetheless
comprehensive. What is impressive is that Langen focuses on *ideas*
behind chess. It's not a big book, but I like what I've read so far.
Suited for beginners/intermediate.

And if it matters, I also have Patrick Wolff's excellent "Complete
Idiot's Guide to Chess" (2nd ed).

So in short, any thoughts/impressions on Langen's "Coles Notes: Your
Guide to Better Chess"?
