huge difference between blitz and rapid rating

In Blitz and Rapid you can select games with playing times like 30!10. I understand this means a 30 minute game with 10 seconds per move. If you move faster 10 seconds then the remaining seconds are added to the game clock. So if you played your first move in 2 seconds an additional 8 seconds would be added onto your game clock. Is this correct? I think I want to play rapid games but want to understand the rules first. Is there a link I have missed that explains this?

Rapid: 730

Blitz: 1849

Blitz and rapid are different games, requiring different skills and with different ratings.
Some people are better at one, some are better at the other.
Different athletes excel at 1500 m and at 10,000 m running.

I would assume so. And so what? Unless they sandbag it takes 10 or so games to find their bracket.

3+2 im 1650 and 10+5 im 2000

Relatively normal g you don't play much blitz

The blitz players typically have higher blitz ratings than rapid especially at higher levels like 2000+ blitz

Like my rapid is 2100 and blitz chess is 2200 (bullet 2100) I mostly try to keep even in most time controls besides blitz cause I need to have the right tempt of moves (it makes your opponents blunder more sometimes if you play fast but not too fast ) so bullet is good for that you also should play some rapid so your chess doesn't go entirely dumb but blitz is good enough for faster thinkers while slower thinkers need rapid

Basically bullet=time management

Blitz=intuition and fast thinking (realy good for endgames and openings )

Rapid =better thinking
