You don't have to learn openings. Sound principles should bring you to 1400 elo (wich is around 1600-1700 here).
Actually you will learn while playing. At some time you will have trouble with some opening moves from your opponent, that is either giving you a bad score or are very popular. Then it may be time to study these moves (= this opening) and find out where you can improve either your own moves or your understanding of the resulting positions.
You should know the most basic pawn and rook endgames + the basic endgame principles. The best place to learn are vere individual. But any endgame beginner course should be a fine beginning (books, online, video etc.).
Don't set an elo goal. Set activity goals and celebrate when you have learned someting new and usefull.
Hi. I've been playing chess for a week or two (~1200 on ) and I have a few questions not answered in the (great) FAQ.
At what point is it necessary to learn openings? Mostly I just try to develop pieces and control the center without a specific plan - is this OK?
What are the endgames I should know? I currently know K+Q, K+R and R+R. What are the most common, and where's the best place to learn them?
What is a good Elo goal to aim for if I'm playing and doing tactics for 1/2 - 1 hour per day?
Thanks.
