Stylizing Chess 960 as 9LX is Absurd!

Even though, in English a large number is is often broken down into digits and pairs of digits English speakers comprehend it as an abbreviated way of saying the entire number. For instance in English we can call the current year either Twenty, Twenty One, or Two Thousand Twenty -One. It’s our English speaking choice.
This former abbreviated form is not done in many other languages, only the later method of stating the actual number.
Since Chess and it’s variant 960, are both international games played by many folks who speak other languages stylizing it like this 9LX, seems like it was done by a monolingual American. That can not communicate in more than one language.
To those of us who can think bilingually, or even multilingually, it looks ridiculous to have the Arabic numeral 9 followed by the Roman numerals LX.

Well English is the most spoken language in the world. Airline pilots in every country has to speak English in order to be an airline pilot. Flight Niner Six Zero taxi to runway One Niner. I honestly don't see the 9LX as being much of an issue personally myself.

Yet it seems more and more common. Why?
Because they don't play chess 960 but chess 959. Rules of those tournaments explicitly exclude the standard starting position. Chess 9LX looks goofy, but somehow less goofy than chess 959.

Although "CM" indeed is a valid way to express "900", subtractive notation was far less commonly used in Roman times than you would be led to believe. More likely, you'd see "DCCCC".
Anyways, my preference is "960".

3-character acronyms are just more marketable, especially when a number is combined with letters.
Just like a car with three wheels is far more eff ... oh wait.
Anyway it's the commercialism that often seems absurd to the technically-minded person, yet it's the truth of what works in the world.
In this case I do agree though - 9LX sounds like a bike brand. And so what Fischer had some mental problems. We all will as the brain inevitably degrades above 25... and at 37 I can attest to that. Let's just traditionally call it Fischer random or random chess.

Doesn't matter what we call it - we are referring to the number 960, which is translated to either CMLX in Roman Numerals or DCCCCLX in modern Roman Numerals.
On places like Reddit and Quora, the only people who call it Chess 9LX are people who don't play much chess, so it's a good way to distinguish between a player and a patsy.
To use a term popularized in the press conferences of the recent WCC, "absurd" , I think it aptly describes the written term 9LX. Ridiculous, ludicrous, silly, or even stupid are also appropriate terms. I like the term 960 better than the former Fischer Random. I also like using roman numbers. Nine Hundred Sixty expressed in the ancient Latin number style is CMLX. To write and combine the Arabic numeral "9" and Roman numeral LX, looks silly, or better stated absurd. Yet it seems more and more common. Why?
