Are you new to Chess? You probably just need to practice some more. It's nothing to be ashamed of.
A great series of books that relaly helped me was the Winning Chess series by GM Yasser Seirawan. He goes over the basics of the game in book 1 (Play Winning Chess), and then goes more in-depth with Winning Chess Openings, Winning Chess Tactics, Winning Chess Strategy, Winning Chess Endings (about the endgame), Winning Chess Combinations, and WInning Chess Brilliancies. In particular, books 2, 3, and 4 really helped me understand more about the game; and they're not just for beginners! I'm sure intermediate players would also benefit from reading some of these books.
i cannot seem to play any good chess when i don't play against people that just blunder their queen or fall for simple forks/checkmate patterns :( it's really depressing to be honest :S i would appreciate it if someone could have a look at my games and tell me what i have done wrong.
