Nd5 afetr basic 4 nights

Please let me know some theory about Nd5 after four nights( When all 4 nights come out after 1. e4 e5) Please use an engine (I don't have one) and let me know
Thanks!

So if you know what 4 nights is, it is when all four nights come out after 1. e4 e5, i was playing a game and i played nd5 after this, this became very interesting, and i wondered about the theory in this, please give me some theory on his move. Thanks
(This is my real question)

Seems like white is attempting to be aggressive for control over the center but Nd5 does not seem to lead to any advantages for white.
After the variations i looked at black does not have an e or d pawn anymore but they quickly make up for that by bringing their rooks into the center and they seem better off than white.

Thanks, this is also very interesting, if black's night captures the pawn there are many traps after Qe2 F5 d3. that is the line I played and it worked out well. Try playing a game with this, it can be weak but it does work.
