Hello I'm new, what time control should I play?

The longest time control I have ever played is 15+10 and that's plenty.

longest was 30 min AND IT WAS FREAKING BORING. SO IM BACK TO BLITZ

I am extremely surprised IMBacon hasn't posted the opening principles list yet, so I will do it myself.

DISCLAIMER: I do not own this content, but I guess it is in the public domain. If turns out to be a registered trademark of Diakonia, Inc. then I'll offer my apologies.

Opening Principles:

1. Control the center squares – d4-e4-d5-e5.
2. Develop your minor pieces toward the center – piece activity is the key. Centralized piece control more squares.
3. (King Safety)
4. Connect your rooks. There should be no pieces between your Rooks.

The objective of development is about improving the value of your pieces by increasing the importance of their roles (Piece Activity).  Well-developed pieces have more fire-power than undeveloped pieces and they do more in helping you gain control.

Now we will look at 5 practical things you can do to help you achieve your development objective.

They are:

1. Give priority to your least active pieces.

• Which piece needs to be developed (which piece is the least active)?
• Where should it go (where can its role be maximized)?

2. Exchange your least active pieces for your opponent’s active pieces.
3. Restrict the development of your opponent’s pieces.
4. Neutralize your opponent’s best piece.
5. Secure strong squares for your pieces.

Don’t help your opponent develop.

There are 2 common mistakes whereby you will simply be helping your opponent to develop:

1. Making a weak threat that can easily be blocked
2. Making an exchange that helps your opponent to develop a piece

I would think that for someone who is essentially beginning--starting over--there's a point where a longer time control just isn't worth it anymore. I totally agree that 15+10 is a good control that provides ample thinking time, but once you get up around 30 minutes to an hour, you've got way more time on your hands than your calculating ability is able to fill. Once a player has gained a lot of experience, they are able to dig in a really do a deep think productively. In the early stages, though, I would think gaining a lot of experience with more moderate controls is more productive.

15 minutes is certainly inferior to 30 minutes for example. I tried 10 minutes a few months ago in an arena tournament, lost a few games on time, and generally played a lot worse than in my 1 hour per side games (I lost in one day more than 50 rating points). Beginners in a lot of cases have to take their time in the opening as well, in order not to be lost after 10 moves of play. 

I am 1 500 now, so I could probably get away with playing 15+10, but I would still on average play better games with longer time controls. 

I lost over 100 in a day.... very sad tournament

Sometimes it takes me more than 5 minutes to find a move. If I've played 15 minutes per side I would be lost in who knows how many games because of time trouble. You can certainly learn by playing 15 minutes per game, but in my opinion, the longer the better. It doesn't mean you need to play a really long games but 30 minutes is certainly better than 15 minutes. When I play casual games in person, I sometimes take even more time.

I would suggest 15+10. Its the best

30m

Eternity.

Standard 30 minutes, up to you if want to add increment...

Welcome back. I'm guessing the Queen's Gambit show will get more people into chess or back into it. I've only seen a 2 minute trailer of it but I really wanna watch it.

15/0

or anything with increment

Specifically, what is it that you want to improve? What I mean is, say you've just watched a video on planning or Imbalances, for example, and you want to practice these techniques in your games to improve. How long is it going to take you to break down the position and come up with a plan the first few times you try it? 10 minutes? 20 minutes? You might decide you need a 45/45 for this. Spend some time working out what you want to improve, then how you want to do it, then how much time this needs in a game to do it properly. The answer will pop out.

I think 10+5  , and watch pogchamps 1 and   xD
