Trick North East South West
1 ♠Q ♠K ♠6 ♠2

3 ♢6 ♢3 ♠3 ♢K
4 ♢Q ♢8 ♡3 ♢9
5 ?
Lead: ♠6
The declarer wins with the ♠K and runs two top ♢. You win with the ♢Q in the third round. Your partner discards ♠3 and ♡3. And now what's your plan?
The declarer could win 4♢, 2♠ and 2♡. ♠3 shows that your partner holds 5♠. Assuming that you return ♠ now, even if your partner holds ♠A, the declarer could return back twice easily to finesse ♡. In other words, discarding small ♡ and ♠ indicate that your partner doesn't hope you to return ♠. So shifting to ♣ is the only choice. To a player with certain experience, shifting to ♣ is obvious. And now the problem comes, which one to play? Will you play 5 casually? You just have 2 entry to through ♣. Assuming that you play ♣5, it does show that you hold 4♣ with top, unless the declarer holds both 3 and 4, you need 3 entries for follow-on defense. And it might encourage your partner to continue ♣, although after deep thought, your partner should not continue with ♣. You do dig a hole for your partner. For follow-on defense, ♣9 is a better choice. After winning, your partner will choose ♡ or ♠ according to his cards.
PS: If you return with ♣5, this deal becomes a playing problem. Here I will not go further on this issue.
