Divide Volley. Two people continuously hire someone back and forth and 1 of them makes profit of it....my explanation is terrible there's guides about it
dv = drop volley 2 players hires an inactive or noob tut and ofcourse a certain person (can be anyone between the two of you or a 3rd person) will hire it after it reached a certain value. d person who have the volleyed tut will lose money ofcourse (he'll be the one to drop) and his partner will gain.
