PP 40k Guaranteed hand, Checkraise on All Club Flop

Recent History: Have been on the table for 27 hands. Rose once with AA from MP (winning with postflop bet) and once with A8 from button (taking down blinds) without showing. 5 hands ago, I won a very big pot, which went to showdown, when I flopped a set of 3s on the button. The hand right before the hand in this thread, villain minirose my bb, and took down the pot with 1/2 pot bet on an Ace high flop. Villain has not been particularly active, but tends to overplay hands if he has taken the lead in a hand, IMO.

1) Assume I don't have a club. Given the recent history, is this a reasonable move, or am I chip spewing? Thoughts?

2) Now I assume I have a club. Does it make a difference?
