1) I first studied chess seriously on Wikipedia too :)
2) How about you post some games of yours, and annotate them here? I'm to lazy to get into your profile. To start, post one loss of yours and I will comment. (If I don't, message me if you want)
What are my weaknesses in chess?
Sort:
Play knight on d2 square
don't expose both the sides. castle safely
Don't keep king in centre. don't advance f3 pawn unnecessarily. Even though you won the game. Follow these advices.
g5 was unnecessary
Like with pretty much any other beginner, I want to improve my chess skills. Other than the obvious answer to play more, I would probably focus on one aspect of chess (e.g strategy, tactics, openings).
There was a nice guy who advised me to 1) advance my center pawns first (to take control of the center), which I have done and 2) take care of hanging pieces (pieces that are not "watched" by any other pieces) which I sometimes accidentally ending up doing (aka blundering).
I've done a little research on chess, although admittedly, it was on Wikipedia :P. I know a little about strategy, such as fighting for the control of the center. I know a little about tactics, since I came from playing Xiangqi (Chinese Chess), although I didn't play a lot.
I still make stupid mistakes (e.g losing my rook to a bishop from across the board with no way to take the bishop).
Judging from the games on my profile, what is the biggest weakness I should address first? I think my biggest weakness is that I tend to focus on defending rather than attacking (most of my wins are due to when I realize that I have an opportunity to attack immediately with no immediate consequences).
