time management

one word: Concentration!!!

calculating and foreseeing moves

My opening moves is weakest in game, but in the endgame is my strongest move.

Endgames for me are the easiest...Everything is simple and straightforward...However openings specially for black always confuse me >.<

I defintly struggle with openings because you have to be very careful, which I'm not. 

Failing to take the time to think more and consider all possibilites.

Fear! And I always think: there must be a better move than the lousy one in my head. And then I play the lousy one anyway 

Time management & endgames, but man hate endgames the most

Openings : No, I'm familiar with lines

Positional play : Well, I could reach a good position

Tactics : Not much, I know it but sometimes I just miss it

Time Management : Because I am familiar with the opening, I make moves easily and I think well all throughout the middlegame and endgame

Endgames : I HATE THIS PART ! It goes completely random, especially with time pressure

Definintely time management. I think too much!! In the end, I only have a few minutes left...

Winning, I fail to do so almost half my games. :P

Understanding how the tower things move again...

I make one silly mistake and I loose

 I move too quick.

I suck at time managment.

Chess is my weakest point in chess.

Blunders
