Suggestion of new chess variant

I have an idea of new chess variant.
Name: Premove Challenge
Rules: Like normal chess. But on the first move both White and Black make 1st move and premove 2nd. Then in the 2nd move, your last premove is done, but opponent's move is not. So you premove next move. In general, in i-th move, you premove i+1-th move. If the move you premoved is not possible when it should be played, you lose. There are no stalemates.
Maybe you will add it?

And another suggestions. There is very big amount of variants nobody or nearly nobody plays, and some people wants to test these variants. Maybe you will add option to play variants with computer?

I thought of a potential variant idea: Duck chess, but you have an amazon trapped behind ducks. I think it might be interesting to try out eventually.
