only 2 player on the server

Hi!

A am a little bit confused over this... I want to play a normal dedicated public on m yserver but with only to slots/player on.

I have tried to use sv_maxclients 2; party_maxplayers 2
But it didn't worked and I am not sure when I am supposed to write them or if it works at all.

How can I play 1vs1 on a public server I create?

Thanks

Did you also use these?
sv_minclients 2
party_minplayers 2
