I'm looking for some books that I can learn from. I've known chess for years, but I haven't taken it seriously until now.
Can anyone recommend some good books for me to learn from?
YES (as you've probably noticed already) and I recommend you also start searching right here for articles and blogs written for beginners
Since you asked MCO is a reference book probably irrelevant for players rated under 1600 Fundamental Chess Openings (FCO) explains basic ideas and concepts of openings and would be more appropriate, but unless you've got lot of spare change I wouldn't even suggest that right away.Instead, consider one or more of these books, look for used copies at amazon
Common Sense In Chess by Dr Lasker
Chess Fundamentals, Last Lectures, My Chess Career all by Capablanca
Logical Chess Move By Move and/or The Most Instructive Games of Chess Ever Played both by Irving Chernev
GOOD LUCK!
I copied this from another thread "The Stappenmethode ("steps method") is used by the Dutch chess federation to teach kids. An American site for them is here: http://www.chess-steps.com/ They remind me of Yusupov's books in that there is a big emphasis on exercises, and a mix of subjects. Mostly tactics though.
The workbooks are most important, they're only $7 each. I don't think the manuals are that important, it's exercises that count. Step 1 starts at beginner level, the end of step 5 is probably 1900-ish.
I would do workbook 1-5, and if can do step 5 well, switch to Yusupov.
