An interesting end position

 After two passes, East makes a nuisance of herself, opening a preemptive 3♣ . You consider passing, hoping that pd can find a TO dbl, but eventually decide to bid an aggressive 3NT.

 West leads ♣ 3, and east plays the nine. You have 2 ♠ , 3♦ ,1♣ and 1♥  at minimum, with a number of chances.

You win the queen, and decide to play a heart honour from hand rather than crossing to dummy. You decide that your LHO is more likely to hold the ♥ A, and if RHO has Jx or Tx, that wd help you set up the ♥ 9 in dummy.

Surprisingly, RHO wins the Ace, and returns a ♥ . That puts paid to your plans of setting up ♥ 9 as it seems very likely that LHO started with JTxx.

You next try a ♠ to Ten, not without hope as RHO has already shown up with ♥ A and ♣ AJ.

No luck, RHO produces the Jack and shoots back a spade. You win the king and cash the ace, discarding heart from hand while both opponents follow suit.

You now have 2 ♠ , 1♥ and 1♣ . If diamonds are good for four tricks, you can endplay RHO into giving you the ♣ K if she started life with 2326 or 2317. 

Since you need to cash at most two diamonds for endplay to work.. you cash Ace and King, RHO showing out.. Oh well.. another game bites the dust.. or does it?

Here’s the position

 When you play the ♣ 5 to RHO, LHO can discard a heart, but what should he discard on the next club – whether his partner cashes the ace or plays a club to your King?

He’s squeezed in three suits – without the count. And you have your 9th trick afterall.

Does the defence have an answer? They don’t, but they DID. Until the previous trick. Yes, that precious ♣ 2 that your RHO discarded on the ♦ K. If she holds onto that, she can underplay your ♣ 5 with ♣ 2. You are bound to get a ♣  trick in this position, take it now. But now.. no squeeze. Partner has ample room to guard all three suits.
