How to speed up ?

What is best way to increase fast thought speed process.  I am usually able to win against the computer at my chosen level (4) but only by taking time over each move...game usually lasts an hour. So what is best way to increase speed and decision, practise playing lower level games or more difficult games ??

As a recovering addict, I have taken to chess as part of the rehabilitation process. So the suggestion is not particularly helpful.

I was only joking  any sensible suggestions ??

Why do you want to play faster games?

Games lasting an hour are 30 mins per side, not particularly slow.

Playing against computer means 59.75 for me and 15 secs for computer. I dont expect to be as fast as computer program, but guessing the more you play the more you recognise certain situations and react faster ?

Yes, the more you play the faster you may become. 

But for rapid time controls (i.e. G30, G45, etc) you should be using most of your time anyway. 

Are you looking to play blitz chess?

Actually no, I kind of think it is more satisfying to play at against a higher level and think each move through, but on the other hand it would be nice to recognise certain situations and know the direction to take the game. I dont necessarily want to play fast games, just analyze in a shorter time.

Everything takes practice....to play fast or to play slow.

Yeah, so it is nothing but practice then.

Tactics, playing games, etc. But stop playing against a computer and play live people.. Much better.

Chess is pattern recognition.  If you want to improve, yo need to increase the number of pattens you know. You dont do this by playing faster.

Learn tactics and watch some MatoJelic. The more positions you see, the easier it will be for you to make a plan fast.
