These submission rules do get tedious when playing OTB with a moderator - however, when the moderator is an online software, this variant should be pretty straightforward to implement, play, and develop theory in.

It might feel more natural to allow players to stay in check as they can in Fog of War chess, denying them some protection against direct threats to their King.

Alternative names: Premove chess, Delay chess, Field report chess. The last name imagines the players as generals, who only receive information about their battles periodically, and have to give commands in advance.

One thing to note is that both players can think about their move simultaneously, as they will know their opponent's last move as soon as they make their own. This might necessitate a more precise definition of the clock.
