I don't think apartheid is really a great term to use for this.
pre-moves-apartheid required ?

Perhaps an Americanism is better (choose one):
- Segregation
- Separate-but-equal
- Internment
[EDIT: FWIW, I'm with Phrage - it practically qualifies as a variant by definition]
[EDIT2: WRT word choice, I'm with ivandh - by definition 'apartheid' implies race discrimination]
As for the word apartheid... no, not really all that appropriate.
As for the content of the OP, if you don't like that someone is using pre-moves against you, then simply make a move on your end that is out of the ordinary and unexpected, that usually helps.
To the argument that something should be done because there is no equivalent OTB, this isn't OTB anyway, so why should that hold any water?

apartheid means a separate area of existence- apart-hood, but rather than attack the term consider the idea.
("not appropriate" is a phrase for phusspots wearing tin shoes and drinking tepid milk who go through life in high dudgeon being ' deeply offended")
If we remove the close connection with OTB chess does live chess not then become something else -a joystick video game ?
What of the notion of announcing in your invite that it is a pre move chess game ?
One is always free to insist on a bonus addition which gets around the premove silliness a bit but I do believe the invite should say whether premoves will be used at least

And "apartheid" is a word for racial division in economic, educational and social rights and welfare. Which now that I think of it is a pretty good term, those degenerate premove bastards ought to be in their own compound without getting their grubby hands on our pure and unspoiled ratings.
I don't know (but you're weird, and I like that).
You can never be a politician now.
because it was possible up until 20 minutes ago.

polymath, polygraphist, pollydollys club for pvc admirersm and polymorphous perversity university positions still open and hiring however.

Live chess has pre-moves. Online chess has conditional moves. Never the twain etc. Just take oph the phraught phrock hun and you'll be phine Phezzique
premoves can be switched on or off or on for one player and off for her opponent.
So pre-move discordant games are played.
many skilled newbies get crucified by pre-moves and yell "cheat"
There is a type of low skulldugger member who lies in wait for a 1200 rating and pounces on pre-pre move neophytes.

Paaulty Phuzzy Connection Phezzique -your opponent does not reach five moves into the phuture on OTB games unless of course your OTB board and you have recently moved to a multi dimensional with a side order of coleslaw universe.

I'll try to elucidate.
Premoves are like foreplay. Those types of extended intimate encounters are segregated like South African Apartheid from Quickies.
We should categorize our romances in terms of years of racial abuses.
I hope that makes sense.
But those are strictly in terms of SubDom relationships.
And by pre-announcing pre-moves, Phrage (reasonably) thinks partner-opponents should agree to a safeword.

Hilarious!
As live premoves have no equivalent in OTB chess, should they be relegated to a separate category of game like 960 ?. Would including "premoves on" as a detail of game invites be a good compromise ?
Do premoves have an unsuspected playing field levelling effect ironing out differences in access speed or mouse versus touchpad ?
