Weird set hand - 2/4 6max

[TheWorstPlayer]

Only been at table an orbit or two. Villain hasn't done anything too extreme, but he has raised maybe three times in the first two orbits, once to 6bb from the BN against one limper so perhaps he is aggressive, but perhaps not, obviously too early to really tell. What do I do on this turn? What's my plan for a club river, assuming I get to the river? What's my plan for a diamond river? What's my plan for a T river?
