P in 4th seat has:
♠ -
♥ Kxx
♦ QTxx
♣ K987xx
Is this hand worth a 3♣-bid? IMO: No!
What else to bid? - Pass.
This hand has quite a lot of minuses, ie
- not enough playing tricks, let's say 3 - 4. AQT9 is behind, always
- void, here in ♠, it is usually not that good if your hand has a void if you make a preempt-bid
- the effect of the preempt is not that big, the entire 3-level is still available; compare with a 3♠-bid: here the opponents have to bid on level 4
- the game is IMP, what part-score do opponents have? maybe 2♥ or 2♠, who knows? what is our score? on a lucky day partner has the perfect dummy, and 3♣ makes, but usually not, so after a hard battle 3♣-1 or -2
Having said that: With a "Pass" with this hand in this situation you gain more than you lose, at least in the long run.
Edited: "lose" instead of "loose"
