I might ask myself the same question after looking at this one game. White gets the advantage of moving first. By moving a piece out and then back to its starting square, it looks like a deliberate way to give yourself a big handicap.
Still, it probably wasn't as bad as the previous game. Nh3 is one of the worst ways to open a chess game. (A knight's power depends on how many squares it can move to. Moving a knight to the side of the board keeps its power at a minimum.) Moving the knight back to h3 after being chased from g5, you are close to being lost in only 3 moves. These moves are so bad that I find it hard to believe you aren't doing this deliberately.
On the off chance that you are serious, I think you need to start with a book on basic tactics, the relative value of pieces, basic mates and so on first. There are many. A popular one is "Bobby Fischer teaches chess".
Anybody know any good openings I should experiment with?
