The awesome 'Dunst' opening 1.Nc3 often also is called Van Geet opening,
https://en.wikipedia.org/wiki/Dunst_Opening
As you can see in the above article, there are no clear standards for opening names
(in the situation of gambits or unconventional openings the situation is even worse.
Anyway, the Dunst-Perrenet gambit is an awesome opening gambit:

Perrenet, just like van Geet is Dutch chess player
https://nl.wikipedia.org/wiki/Jacob_Perrenet
apparently still alive.

Named after French player Pierre Morra (1900-1969) and American chess and poker
player Ken Smith https://en.wikipedia.org/wiki/Ken_Smith_(chess_player)

After lot's of analysis (e.g. by Esserman), still playble (at least up till IM level,
depending on time control).

nr 55

with an awesome anti-Pirc gambit. Not played so often, for unclear
reasons; Black is losing two tempi and White gets a lead in development.
Called Roscher (*) gambit, but played by many others, often declined
(eg. with ...g6) by higher rated players.
Nb this one was still with an older version of Knightx(4.6), in coming games
version 4.7 will be used of course.
