This move reminds me another famous move played 30+ years by O Meien. Luckily, with Go4Go it is fairly easy to locate that game:

If you are going to give references to games I think it would be nice to just include the SGFs instead of a link to a site which needs a login. Last time I tried to register for the site it failed.
