After a quick look at your games - if you do just one thing: after you decided for a move, put it there in your mind and thing of what the most annoying move of your opponent might be if you do that. 1/3 finding a move 2/3 of your time do what i just described and you are 1000 tomorrow!
I m doing very good according to me but somehow I got checkmated in no time . castling and all these things I did but no results. these tactics things never come in my game.
it's so frustrating.
