Hi!
In general, here are three things you can do to improve:
1. Try to study your games (especially your losses). Post them in the forums for assistance if you're not sure what's going on. But it's important to try to find out yourself what's going on.
2. Read chess books and learn from the masters. You can check out my recommended book list on my site: http://www.betterchesstraining.com/2014/05/chess-books-for-beginnners.html
3. Do tactical problems to sharpen your eye. The Tactics Trainer here is great, but also from books. Check my list out again for the book I recommend.
If you do these three things regularly, your results will get better.
I hope that helps.
Best regards,
Bryan
I'm pretty terrible at chess. Anybody have some tips?
