It's easy to forget that and pretend that just because you can see the problem your opponents can too. With that in mind have a look at this hand:
| ♠ | A K Q 9 5 |
|---|---|
| ♥ | J 5 |
| ♦ | A 7 5 3 2 |
| ♣ | K |
Here's the start to the auction:
| West | North | East | South |
| 1♣ | Pass | 1♥1 | Pass |
| 2♣2 | Pass | 3♦3 | Pass |
| 4♦ | Pass | ? |
- Transfer
- Natural but denies 3♠
- 2♦ would be non-forcing
Slam looks likely but what's the best way to get there? You could use keycard but if partner has two you're in six and might be off two cashing hearts.
You could cue your spades but partner is most likely to cue 5♣ and you don't know any more. Even without the ♣A you may have 12 tricks available.
I realised too late that, the best solution, was to cue my heart control.
