Unusual Opening
Decent unusual openings:
Grob(aims to fianchetto the light squared bishop and occupy the kingside), Polish (aims to fianchetto the dark spaced bishop and occupy the queenside), Anderssen(aims to support later moves flexibly, a mirror of the St. george Defence)
Mid unusual openings:
Ware(not good, but not bad), Kadas(same idea),Saragossa(Aims for either supporting d4 or early queen development)
Bad unusual openings:
Barnes (hinders the knight), Ware Opening: Meadow Hay Mistake (gives your opponent less central control but at too great of a cost), Kadas Opening: Beginner’s Mistake (Same thing), Barnes Opening: The Wrongcloud
Idk about Mieses opening or Van’t Krujs opening.
this is just my opinion. some people will say anything other than e4 is bad.
