Lead is ♠T: ♠T-Q-J-4
Declarer next plays ♣ from dummy (agree?): ♣2-5-K-7
How (and why) would you continue from here?
Thanks,
Koen
(I underlined the card that takes the trick; bold the card of declarer: is there any standard convention on how this should be done?)

It looks to me that your best chance is to hope that RHO has the ♣A and one of the minors to be breaking. Cash ♦s discarding ♠s and play another ♣ from dummy.
Even if ♣ do not break you next establish a ♥ for your ninth trick before opponents can take 5. Likewise if ♦ are 5-2 you should still make if ♣ break.
This assumes that either ♠s break 5-1 and at least one ♥ honor is with RHO or if ♠ are 4-2 that RHO has the ♥A.
You have to go up with the ♠A if opponents continue with ♠.
The alternative of playing for ♣s to break and playing next a low ♣ from hand is unlikely to work since opponents will probably try to establish 3♥ tricks, unless the ♥Q is on or either opponent had ♣Ax.
Of course LHO may have ducked the ♣A.

Thanks Rainer.
Don't you always need the Heart trick if RHO has Club Axx?
I did run the spade from dummy (RHO not following), hoping that I could end-play LHO some time in spade for trick 9. How bad was that?

Of course (unless you try establishing ♣, which I do not suggest). But the timing is crucial. Opponents are likely to switch to ♥s next, which will likely give them 3 tricks or more in ♥s plus the ♣A. So they may have 5 tricks quickly. Therefor you need to establish your ♥ trick last as your ninth trick, so that opponents can not cash length tricks there before you cash 9.

If I would see 8 tricks. But again I would expect them to establish ♥ next. Now they very likely will have at least 4 tricks before the end-play can materialize.

♠ 4-2 and RHO has ♥ A and ♣ 3-2 with Ace onside ,5-2 ♦.

When u play 2nd ♣ from dummy after 4♦, he takes his ♣ A, cashes 5th ♦ if he had 5 (doesnt matter who has 5), and exits with his last ♠. Seems like they can score 2♠+1♦+1♣+1♥ if i am not missing something.

Regardless though Rainer, your line seems to me the best, as usual.

Thanks of the answers.
This was the complete hand.
The actual play didn't really matter given the position of the ♥ honours.
