(1D)-1S-(P)-3NT-AP

Lead ♣K. RHO will play low to show an odd number (if you trust a random BBO).

Clubs will keep being led until you take it

[wclass___]

Possible LHO club holdings are ♣KQx; ♣KQJ; ♣KQJxx; ♣KQJTx

♣KQx
->most probably LHO doesn't have 4♥

Take 3rd ♣; ♦Q; ♦A

If LHO has 4♦ he is either 3♠3♥4♦3♣ or 4♠2♥4♦3♣ 12-14could, that leaves RHO with no more that 2 points.
Finesse ♦J; Then cash your high ♦ and dicard ♣ (unless RHO doesnt discard 2 ♣)
If RHO discards at least one spade, ♠Qx isnt dangerous anymore, ♠A, ♠...
If he discards 2 ♥, play ♥A, ♥ to ♥T establishing ♥. Actually you will win even if LHO has 4♥. Unless ♠Kx, ♥Qxx, ♣KQx, ♦Jxxx that most probably isn't an opening or ♠Kx, ♥QJxx, ♣KQx, ♦ Jxxx with brilliant lead.

If LHO discards ♣&♥ play ♥A, ♥ to ♥T. Either RHO had 4♥ and you establish ♥ or he had 5♥ and you will get spade.

If LHO has 5♦, use same idea, ♦T, ♦A and look onto discards.

♣KQJxx
take 3rd ♣, ♣ position will be clear. ♦Q;♦K;♦finesse;♦A.
If RHO discards one ♠ and 2 ♥, most probably he has sth like ♠QT9 ♥Qxx left. Endplay him: ♠A, ♥A, ♥K, ♥.
Other main chance is stiff ♥honor with LHO.
Other endings where you have a chance you should be able to read too.

♣KQJTx go like KQJ start, you should be able to differ these by RHO's discards.

Problem feels too extensive, please give more info next time.
probably there are some imperfections in my analyzes.
