What's the best way to up my rating fast?

I looked through some of your games and i would recommend the Sicilian Defense. Learn to use c5 as a response to e4
Also, tactics, tactics, tactics!
Lastly, a few things that will always help your game.
1) Develop your pieces on the side you want to castle
2) As a general rule, trade your knights for bishops (exceptions apply)
3) After castling, try to avoid moving your king's protective pawns

This guy's really sick though. He may not last long.

the fastest way up is not going down
true, it might seem shallow, but it's deep


Looking at your games the first suggestion would be: Stop hanging your pieces!
This pieces are not hanging, these are a combo involving sacrifice.
I'm curious which game(s) are you referring to.?

That was ill-intented sarcasm, sorry ^^. But I have not looked at your games yet, so there might actually be nice combo and sac in them.
