As a dance host (for ballroom, not salsa), I always default to smooth or rhythm unless I know that my partner dances International. I ALWAYS start my dance with the most fundamental and basic steps imaginable. (Box steps are good for rumba, fox trot, and waltz. NOT SAMBA!!) Depending upon her confidence level, connection, and ability to follow, I adapt accordingly. I can usually access well. If I fail to access properly, I apologize for miss stepping.
