This is Andersen the A pawn. Continue the story.

but the dream ended with the king running off into the woods when Andersen reached the 7th rank.

and suddenly killed the queen

totally accidentally of course

but he was charged by Parliament with regicide and, thus, treason anyway.

but it turned out the Queen was a mannequin so everything was cool.

Unfortunately, the motion to execute Andersen under treason was already passed and there was no way for Andersen to reverse the motion, so to the gallows he goes.

but Clint Eastwood was his golden haired angel and followed him wherever he went.

Unfortunately, Back to the Future III happens 180 years before this, so Clint Eastwood can't help Andersen (and likely has no idea who Andersen is).

But, fortunately, Andersen borrowed a time machine and went to 1845, causing a disruption in time

And Anderson find the king henry the third

but he was fortunate to be in 1845 before internet banning was invented.
