Blitz and Bullet are not chess

I would say that classical chess (40/120, SD/60) is the best test of a player's true skill.   Unfortunately, nobody wants to play a classical game online for 4-6 hours.   A long rapid game, like G/60 or G/90, would also be a pretty good indicator.   

Main reason I barely play rapid (unless it's for a league or something) is because of stalling

Agreed, but online classical play is becoming more popular nowadays because OTB organizers are maintaining their tournament formats with the only difference being that they reflect them virtually.

That doesn't bother me.   It just gives me more time to plan my strategy.   I'll sit there and wait for 10 or 15 minutes if I'm gonna get a W out of it.

I'm not talking about USCF-rated tournaments.  I was referring to sites like chess.com and lichess not having classical formats.   

Yeah, that is unfortunate.

But if you want slower live chess games. You may be interested in joining the following club which hosts 45+ minute games on a regular weekly schedule. https://www.chess.com/club/slow-chess-league

I've been in that club for a few years, actually.  I played 3 or 4 tournaments, when I first joined, but then I got busy with other things and the tournament schedule no longer worked for me.   

Ah, I see. I have not yet played in any of SCL tournament but I plan to some time in the future.

I was going to say something like "I hope to play you someday in one of those tournaments", but then I looked at your ratings.  lol   You're a little out of my league.

Certainly not in correspondence chess...

Technically, correspondence chess is playing by mail.   You can use computers and opening books in correspondence chess.   Daily chess is pretty much the online equivalent of correspondence, except that the pace is a little faster and you cannot use computers, but you can use opening books and an analysis board.   I created my own opening repertoire in a Windows Notepad text document, using Stockfish to help me with some of the variations.   Although, I tweaked it to my style of play and don't usually play the #1 Stockfish move.   At my age, my memory is fading, so I can't memorize all of my openings more than 5 or 6 moves deep any more.   But I never use a computer during a game.

I was under the impression that "daily chess" and "correspondence chess" were essentially synonymous terms. I needed re-education.

Close, but not quite.  I love daily chess.   It allows me to be creative and play the best game that I am capable of playing.  

I think that bullet and blitz should be reserved for players who believe that their fundamental knowledge is enough. Depending on their goals, different players strive for different benchmarks. For example, hobbyists will learn and practice fewer openings and tactics compared to a club player. If a player is content with their knowledge, they can then try to sharpen their instincts by playing speed chess. Short time controls require subjective decisions more than it requires objective decisions. People will play the move that 'feels right' based on their preliminary analysis of the board. So, experience and talent are the most important factors for speed chess, while calculation takes a back seat. Or, players just want to have fun and proceed without a conscious effort to learn. These are just my thoughts, and I am completely fine with how things are right now. People should play what they want to play.

One PGN file consisting of multiple games, in this case ten. Does that clarify?

My correspondence rating is a wee bit higher than yours, and I rarely can see ten moves deep. In OTB play, I can point you quickly to the three games (ever—in a quarter century of active play) when I calculated nine moves ahead. In correspondence, I have sometimes, maybe often, played out a position on a chessboard, on the analysis board, or more often in my database twenty moves or longer, but I rarely take these seriously beyond about three moves because there are simply too many branches.

Not on this site.

I played two classical games on LiChess yesterday. My local chess club just finished our annual Turkey quads online. I organized the event. The time control was 75+5, a little faster than what we would have played OTB, but still a classical time control. Some exceptional chess was played, too.

They are.

Allowing engine use varies. USCF forbids it. ICCF finds it unpreventable. Chess.com forbids it. Kingscrusher acknowledged to me that it is likely common above a certain level on his site. 

The trick to playing good blitz is to learn how to evaluate a position only a few moves deep. You don't have time to calculate several moves in, like in classical.

You have to look only a few moves ahead, then make a choice, based on that limited depth.

It's definitely not as accurate as standard chess. But that's also part of the fun: trying to play good chess when the clock is working against you.
