what mode i should play?

Hi everyone! im new in chess i i wanted to ask you all what time mode i should play to improve my level? 3 mins,10 mins,15 mins? I started with 10 but i like more 15.

If you want to improve play 10 min or more.

5min and 3 min won't let you think about your moves for so much time and won't let you improve your play.

But another thing is time managment which is a different thing

Thanks!! im gonna stay at 15 mins ! with 10 mins i always run out of time

Maybe 15/10 so you have 15 minutes and you get 10 seconds added to your clock for each move. That lowers the risk of a timeout and it gives you a good amount of time to think about your moves. 

15 minutes at least. When I was a beginner, I needed time to think. I may not have played the best moves but the last thing you need is to feel the pressure of running out of time.

The chess mode

I recommend beast mode!!!

15|10 is the official FIDE rapid time control and is best to improve.

The Time-Control You Enjoy The Most Is The One You Should Play To Get Better.

why are there 16 caps ?

I think it depends on what you are in need of improvement, if you want to improve your game, it's a good idea playing games that is 15|10 or higher, if you need to improve your time management, play blitz 5|0 or rapid 10|0.
