Best time control for getting better

If you want to build a solid foundation and improve your understanding of chess principles, tactics and strategies, staying with a longer time control like 10 minutes can be beneficial.

@#6 chess is not about rushing...the reason you lose is because you are not using the time given to you... especially if you know the move you are going to play within the next 10 seconds...if you see a good move right away, you need to take more time to look for a better one...that is the key to improvment

I play 10 minutes a lot, but I guess it depends on what type of person you are. If you typically need more time to think, then go for 15|10 or even 30 minutes. If you make great and fast moves at the same time, you could try 5 minutes or lower. Depends on you.

Blitz is never the way to go if you are looking to improve....you have to put in time and effort...if you don't study you will never improve...and if you never practiced what you learn you will never improve either. So if you are studying and learning but you only put yourself to the test with blitz, it's not going to work for you. Now maybe you'll improve 100 points or so. But you'll never actually get anywhere unless you put in some longer games so you can learn and apply...after you have learned and understood then blitz is great

3 minute. Lose until you figure it out

That's not how it works buddy

Depends on the person tho typically rapid isn't that great for beginners (unless your older ) something like 5|3 is probably better where you have just enough time to think but not enough time to fall asleep on your moves I see a good chunk of people improve at longer time controls but plenty also hang their queen by move 10 half the time and get stuck

#15 you want as much time as possible without being inconvenient...there is no reason to take the least time as possible in order to get better... going the short and easy way is always more popular...but the rate of improvement is greatly minimized...also playing longer games is critical for an official rating, if you are too focused on blitz the transition of playing a good move because it's the first thing you see, and the opposing thought...that is find a good move and look for a better one, can be very hard to achieve...so learning both playing styles is definitely a benefit... however one is superior to improvment...also a lot of people seem to forget that bullet, blitz, and rapid are all called speed chess for a reason...they are for convenience and speed... But I would never see these types of chess as superior for improvement... but rapid is definitely the closest you are going to get to a casual game of chess "being on chess.com of course" 😆

If you prefer blitz...there's nothing wrong with that...I'm not attacking it, 10 rapid and 5 blitz are not separated by very much...but if you are studying chess, then the longer time is undisputably better

#16/#17 - I agree with almost everything you said. I play about 1,000 blitz games a year and I feel it has given me a better "feel for the board". Let me explain:
When I started playing chess over 60 years ago there was no online chess or even computers. Without a local chess club, it was almost impossible to get a decent game. I had chess books which helped, but those were no substitute for playing actual games. When I finally joined the USCF and started playing tournaments, I often felt lost in the opening after I got out of the book. I'd play the Solitaire Chess game in CL&R and score 1900, then lose to a 1400 player in an OTB game the next day. Playing blitz has given me exposure to thousands of positions in real games so I seldom feel lost anymore. And tons experience with different (and unsound) openings.
I'd say the keys to improvement are study, solving puzzles, and playing LOTS of chess. Just my 2 cents.

Oh, and analyze all of your games. Especially the ones you lose, even blitz.

#18 yeah, blitz will definitely allow you to play more games...
