Time Control Changes?

25/5 is better than 30/0 because of the 5 second increment, it all works out to roughly 30 minute game. If it is one or the other, 25/5 would be best

Let's list every time controls currently available, as well as those that people here have suggested. After the equal sign is how much time they give each player in minutes (taking into account that an average chess game last 40 moves).

1|0 = 1
2|1 = 2.66
3|0 = 3
3|2 = 4.33
5|0 = 5
5|2 = 6.33
10|0 = 10
15|10 = 21.66
25|5 = 28.33
30|0 = 30
25|10 = 31.66
30|5 = 33.33
30|30 = 50
45|45 = 75
90|30 = 110

As you can see, the following time controls are almost equal:
2|1 = 2.66
3|0 = 3
So we need to get rid of one of them. I suggest getting rid of 2|1 and keeping 3|0, because in blitz and in bullet there is no need for increments... The purpose of increments is to stop the endgame from being ruined by time, but in blitz/bullet the entire game is already pretty much garbage so... Increments are only necessary in rapid and in long.

Also the following time controls are pretty much equal:
3|2 = 4.33
5|0 = 5
5|2 = 6.33
So we need to keep only one of these three. I suggest keeping 5|0, for the exact same reason as above.

And we have to choose one of these four time controls:
25|5 = 28.33
30|0 = 30
25|10 = 31.66
30|5 = 33.33
I suggest not choosing 25|5 because it's a little too close to 15|10. Also let's not choose 30|0 because it's still a bit close to 15|10 and most importantly in rapid you want an increment.
So the choice is between 25|10 and 30|5. I would think 25|10 might be better because it's common OTB.

And finally, like I said in an earlier post, we need both 30|30, 45|45 and 90|30. If we take only two of them, there would be a big gap in the time controls (eg. not taking 30|30 would mean that there would be no time control between 30 minutes and 75 minutes, which is unacceptable).

Therefore I would suggest this list of time controls:
1|0 = 1
3|0 = 3
5|0 = 5
10|0 = 10
15|10 = 21.66
25|10 = 31.66
30|30 = 50
45|45 = 75
90|30 = 110

The first two are bullet. The next two are blitz. The next three are rapid. And the last two are long.

(Note: I think chess.com classifies 3|0 as blitz, but Wikipedia says 3|0 is actually bullet. Anyway it doesn't make much difference. And concerning 30|30 it's indeed classified as rapid according to Wikipedia.)

But if you really want to have very precisely 8 time controls for some reason, and not 9, then I would suggest merging 15|10 and 25|10 into 20|10 (it's not as common OTB as the other two, but at least it's very round). (Another possibility would have been to keep 15|10 but get rid of 25|10.)

This would make:
1|0 = 1
3|0 = 3
5|0 = 5
10|0 = 10
20|10 = 26.66
30|30 = 50
45|45 = 75
90|30 = 110

And there would be exactly two time controls for each category:
Bullet: 1|0 and 3|0
Blitz: 5|0 and 10|0
Rapid: 20|10 and 30|30
Long: 45|45 and 90|30

It would be a perfectly balanced list of time controls.

Skynet for president!

Pretty much sums it up nicely....I would do slightly different controls...

Bullet:   1/0 & 3/0

Blitz: 5/0  & 10/0

Rapid: 15/0 & 25/5

( This is where I differ @ skynet:  15/0, & 30/5 or 25/5)

*my reasoning is that 15-0 is a very common pool, and many players prefer 5 second to 10 second increment

Long: 45/45, 90/30

Basically almost the same as Skynet's great post....but i suppose everyone has their pet time controls

What skynet said.

How about chess with just no time control as well for the really true slow chess experience? Especially when it comes to building up mental endurance and stamina.

I like your way of thinking sir.

25 | 5 or 25 | 10, both fine

I agree with 3|2 but not with 25|5 

Stuff increments.

I concur with petrip. You already can use custom time controls but everyone naturally gravitates towards the presets.

Please don't remove 30 | 0 and 90 | 30 sounds fine! :)

Can you please add 45/5, 45/45 and 90/30? It is important that we play slow chess to improve ourselves.

I like 3/2 and 5/2, but if you could add 90/30 it would be nice.

I almost exclusively play 30|0. This is my favorite time control; it's not too fast, yet not too slow. If it is imperative to change this for the sake of "higher endgame quality", then perhaps 30|5?

I would like to see some longer times avalible. I normaly play 30/0. when I put in a custom time of 30/10 or 45/0 it is harder to get a game I would like to see one of these times avalible as standard. longer games help develop my playing.

I disagree with this. Another purpose of blitz is to practice your endgame technique for standard games using the time controls you'd see in a tournament.  Since games in the US are typically played with 5 or 10 second delays, having 1/5 or 2/5 options is good for that purpose.

2/5 is still blitz, but it simulates the type of game you'd play at the end of a long time control.

Pay attention to what people are suggesting.

I agree with most of the posters here, keep 30 and add some OTB settings 45/45 and 90/30

both 5/2 and 3/2 should stay, 5/2 is good for beginneer/ intermediate players as a slower time control

Implementing 3/2 and 25/5 would be great! In addition, I would like to see 45/45 and 90/30 for those of us who prefer slower games.
