++Igor and Jane:: SET SOMEBODY UP. The two meanings are (1) to put someone in a precarious position; and (2) to do all the preliminary things to get someone started on something like a job, project, etc. Also, to arrange for someone to meet a potential love interest: "I'm going to set you up with my cousin. I think you'd make a nice couple."

I can see three meanings: подставить, помочь, познакомить, а как насчёт использовать кого-то в своих целях?
