How to get from 1300 to 1400?

You need to create a custom game, then you can set your time to 30 min with 10 sec bonus.

simple: add 100 rating points

Makes sense - but will I get player accept that custom game ? Or will I have to invite friends to play that custom game.

You should get some takers. You could always invite friends.

you will get random people to play.

I tried setting a custom game at 30 | 20 and did not get any matching. Can chess.com set a new slower game as one of the choices ?

The standard timing for FIDE games is

"90 minutes for the first 40 moves followed by 30 minutes for the rest of the game with an addition of 30 seconds per move starting from move one."

This is classical timing and I wish we should have slightly slower game as one of the default options. I would suggest one at 30 | 20 ( a little slower - good for most of us) and another an 90 | 30 ( close to FIDE).

It could take a little while.

What difference does it make if Chess.com sets the time or you do?

Divide by two the time you spend playing games and use the time you have extra to do a computer analysis (on chess.com) of every game you lose. Look only at the blunders. They are marked with ??. You need to figure out what kind of blunders you are making and find a way to stop making them. 

Good luck.

To get from 1300 to 1400 is simple, just play and win. Blitz game can practice you to avoid blunder and puzzle games can enhance your analytical thinking, but if you really want to improve , fight an opponent rating is higher than you. Gradually , you can adopt his moves

I would really never be able to sit down for a 90|30 game, it would mean I would need to commit to 4 hours. It probably wouldn't go that long but it could and you need to be able to commit to that long.

30|20 is a great time though. Not sure how difficult it would be to implement.

If Chess.com does it, a lot of players will be using it and we will get a lot of players playing it. If I do, I have a manually search a friend to play for it.

Just put a challenge up and wait for a taker.

You said it make sense in post 26, then in post 29 (6 whole minutes later) you say you did not get any matching. Just put the game out there and wait for someone to accept.

So tactics and not blundering seem to be the main things :)

Easier said than done!

Update guys, just won a game with black against a guy who (at the start of the game) was 44 points above me, which takes me to 1329!

2400 is Carnegie Hall.

1400 is Billy's Burger Bar.

haha, that was funny!  I was wondering what you meant also!

You need to practice to get to Billy's Burger bar?

Oh well, whos got a cow going spare? ;)
