Welcome! This forum is far, far less egotistical than all of the other forums on 2p2. A great way to start getting better as a beginner is to play lots and lots of longer time control games. If you play on the internet, a 15-minute game should be long enough. And thoroughly think through your moves, checking to see if you hang a piece or if you allow your opponent to make a killer tactic on your army. That helps out tremendously!
Also, practicing tactics help a lot. A good website for this is www.chesstempo.com
. This will help you focus on mating, since that is essential to know how to do when you first begin. It's free to sign up and play as many problems as you would like under chess tactics.
