the portals move when a piece enters in one?
Portals Chess

So when a piece occupies a portal, does it get teleported back and forth each turn, or is the portal one time use for each piece (unless it moves off)? The former would be pretty fun

I think: as soon as a piece enters a portal, it gets teleported to the other.
thats what the form creator said, but my question was different
Regular chess except there are portals.
If a piece goes on a portal, they teleport to the other portal. Pieces can travel through portals. Kings cannot use the portal if it is in check when it teleports to the other portal
