My tissue fell in a book which exploded into a truck that fell from a transparent cliff that led to a beehive which was full of cheesy rice that got infected by pollen that was spread from a horse that was crying because its mane was trimmed by a bat wrong, so I think the longest opening name is Scandinavian Defense.

The Grob, and drumroll please....

The Ware Opening...

Queen's Indian Defense: Fianchetto, Nimzowitsch Variation, Quiet, Check Variation, Intermezzo Line
