Blitz is not chess

Its not.

ok

And what happens when time is running out in Classical Chess ? There are ocassions were the ability to blitz moves is necessary, otherwise you time out.

Chess and time management are relevant and depent each other...

Once Paul Morphy , I think it was in Paris, he gave a simul playing blindfold, having he's back to the table looking a white wall. The simul exhibition lasted six hours and Morphy didn't move from he's chair...

Is that chess ?

The point of playing Blitz is the ability to blitz some moves if necessary and increase your speed in calculation and accuracy simultanuesly. Some others use it also for opening preparation practice.

You don't play Blitz to understand if you are good in chess, that's why people dissapointed from it.

Chess is partly about intuition and partly about calculation. Intuition is spontaneous and calculation is the 'hard work'. In blitz we rely solely on intuition. This is why we don't get interesting positions in blitz. 

bishop_g5, 

Blitz should be played by people who have already mastered classical chess. For a beginner to play 5 minute chess is just crazy.

Even after having played chess seriously for about 7 years I still consider myself a beginner. The reason? All my games were blitz games.

even OTB games?

You contradict your self pdve. How you played chess seriously for 7 years if all your games were Blitz ?

I don't find the serious of your ocassion!

The problem you didn't played long time controls is that you don't realize that Blitz is a part of the game in situations were needed.

In my opinion , you are not a beginner. Blitz should be played from anyone above begginer level. The fact that people get addicted to it , forgetting classical chess or training technique does not affect the value of playing Blitz. It's not Blitz's fault how everyone spent their time studying chess.

i have played a few otb tournaments with poor results. I've always been perplexed because I used to have a rating of around 1600 blitz in playchess but my real tournament results were always bad. It's only now that I have started playing 15 10 many thanks to chess.com

I would say blitz is chess of course, but a type of chess.  As for the quality of blitz games.. yeah, I've noticed at least in my games my blitz games are basically just shallow chess where simple ideas and tactics often win.  Try those same ideas or tricks in a slow game though and they don't work.  For this reason I'm backing away from blitz and concentrating on slower time controls in order to improve my game.  I think I'm getting bad habits from playing lazy!

If one relies "solely" on intuition in blitz, they'll find themselves in a lot of losing positions quite quickly.

You should still be calculating in blitz—just to a quicker degree.

Yes, there's less time to think things through, and a higher risk of blundering . . . but that's what makes it challenging and fun.

I tend to agree.  I'm probably a step above beginner (1500) and blitz chess has some value, but not much in terms of priority if your goal is to learn and improve at chess.  

I turned to blitz when I was losing G30 games on time repeatedly at my local chess club (rated USCF games).  I was playing fine, often had an advantage even, but I was reaching situations again and again where my opponent had 15 minutes left and I had 2...  So, out of frustration maybe, I decided to practice blitz and learn how to make "moves that don't lose immediately" quickly.  This did benefit me in just a couple months and now, a few months later, I am able to keep up better on the clock and also play in time pressure (not that well, but often well enough) so that I don't lose every game.

Blitz has also helped me learn new openings more quickly.

But I think these two benefits have also come at a cost.  Blitz is fun!  So I kept playing blitz over and over, sometimes instead of standard games or studying and what I noticed is that eventually I developed some bad habits.... I move more impulsively at times now, even when I have lots of time on the clock!  And I also find that I'm making shallow moves at times... so I think playing too much blitz results in some bad habits, and probably doesn't have much value if you want to improve your game. 

I don't regret my decision to play blitz and acquire that ability to move quickly in time control when necessary, but now I'm finding that taking a break from blitz for awhile and playing slower time controls and analyzing in more depth is critical now if I ever want to improve from 1500.

you shouldn't have been playing only OTB tournaments. you should play it regularly in general. join a club in your area, wait for them to decide if you're good enough to do tournaments based on play against members in your club then do a tournament. 

I disagree it is most certainly chess
