Flopped wheel, facing major aggression

[cs3]

reads:
the table had been playing really lose, but villain seemed to be a fairly solid player. nothing too out of line postflop but did like to limp a lot of hands. about 2 orbits before this hand he had pushed a shortstack all in on the turn (flop went check, check) with 2pr, and lost to a set.
