Only you can help yourself. Study tactics. My recommendation: Winning Chess Tactics by Yasser Seirawan
Help me!!

Maybe today is just not your day. Everybody has off days. Maybe try some unrated games until tomorrow and maybe it'll be your day. You shouldn't play players weaker than you or you will get weaker yourself. This is because you will move quicker and make dubious moves. Don't worry, it happens to everyone.
Hi everyone,
In my past 15 Live Standard Games, my record is 0-12-3!!
I have been playing some pretty high-rated players, though...
Sooo... my question is, should I continue playing 1600+ players (my rating is 1511), or should I stick to people near my rating..
Thanks!
Suvel :)
BTW my rating used to be in 1600s, then it went down a little, and 15 days ago, my rating was 1564 (or something)...
