Hi,

I'm having quite the problem.
I notice that when I'm playing chess, I tend to ignore the other players move a bit to much. I mean, I construct a plan but I don't really think about the other persons possible responses.

That not enirely true, I do think about the other players moves (otherwise, I would be quite the awfull player) but just not enough..

How can I alter this, I mean.. You can't possible think about EVERY move the other person could make.

How do you evaluate a position and a plan you have without getting into a shortage of time.. I'd really like to integrate that into my play, as it is essensial

ThQ : )

I always try to look at my weakest squares. Then I think, oh, that would be rubbish if they had control of that square/s. If any of their pieces starts to threaten these weakness, directly or indirectly, I'm on it like a flash. Then they checkmate me with a simply 3 move tactic :)

It is always good to check others moves because they may do a blunder and as a result you may get into a more advance situation than before.

and check to see if you have any checks, then if they have any checks(i dont do this but am going to start because i made a really awesome tactic then he checked me, and i didnt think of the check because it didnt respond to my move)

Ask yourself why your opponent made their last move.  Some moves are strictly for developement.  Others are for tactical and positional play or have a direct purpose in your opponents game plan.  It's your job to figure out which is which.  When considering what moves you are going to play look for hanging pieces (pieces that are unprotected and being attacked), pieces that are causing trouble (again, it is up to you to decide what trouble means -- although a Queen that is a move away from mating you is big trouble), and ways you can take advantage of these mishaps.  When trying to anticipate what move your opponent will make, always assume they will make the best possible move.  Once making your move (assuming it is a move made with a good purpose in mind, such as mate or capturing another piece) put yourself in your opponent's shoes.  What move would you make to protect your pieces after the move that was just made? This will allow you to think several moves ahead.  There is always a possibility that the move you anticipated your opponent making is not the best option they have.  If it comes to that, it's simply a matter of rolling with the punches.  Do what you can with what you have.  Most importantly, practice this way of thinking throughout all of your games.  After a while, it'll become second nature.

Hope I helped (and sorry for the long message, bad habbit lol).

Study compartmentalization.
