♣ A Q

South wins the first trick with the ♥K and plays another heart to North's Ace. How will you play, as East, when the ♥Q is led next?

If you ruff this trick. with a top trump or the 10, you will go down. You will lose a trump trick and a club trick. Instead, you should discard the ♣Q. A fourth heart will not damage you, since if South does not ruff, you can ruff low in the dummy. If instead South ruffs, you can overruff with dummy's ♠Q. Ten tricks are yours.

Q: 2 - What will you lead against 4♥?

South	West	North	East

A: ♠K. This is clearly better than a club lead. Take the East cards now and see if you can make 4♥.

♣ K J 6 4

You win with dummy's ♠A and lead a trump to the jack, winning the trick. You then play the ♥K, followed by the king and ace of diamonds. The ♦J falls from South. What next?

Particularly because of South's take-out double, the odds strongly suggest that South has a doubleton jack of diamonds. You therefore run the ♦10 next, ditching your spade loser. A diamond ruff sets up the suit, and you cross to the ♥A to discard a club on the 13th diamond. You lose three club tricks but that is all.

Q: 3 - What would you lead against 4♠ here?

South	West	North	East
Pass	1♦	1♥	1♠
Pass	2♠	3♥	Dble
Pass	4♠	All Pass

A: ♥8. It is normal to lead the ♥8. However, when this deal was played in a robot game, the robot South led the ♠Q. Take the East cards now and see if you can make the spade game.

♣ K 5

The most likely lie of the spade suit is that South has led from Q J 10, so you play low from dummy, hoping that the ace will show from North. It doesn't, but South is left on lead and cannot continue trumps. You win the heart shift and can then ruff all three heart losers in the dummy. The game is made.

Q: 4 - What will you lead against 6♥ here?

South	West	North	East
-	-	-	1♥
1♠	2♠	Pass	4NT
Pass	5♥	Pass	6♥
All Pass

A: ♠K. The spade lead is more attractive than the diamond lead, since you will immediately set up a trick or two. You must take the East cards next and see if you can make the slam.

♣ A Q 5

You win the spade lead with the ace. You have only one loser in the side-suits, so all will be well unless the trumps break 4-0. It may be possible to overcome four trumps in the North hand, though.

To do this. you must score six trump tricks. You therefore ruff a spade in your hand at trick two. When you play the ♥A, South shows out. You continue with the queen and king of trumps and ruff another spade in your hand.

You are now down to the singleton 7 in the trump suit. North has the singleton Jack on your right. You cash your five minor-suit winners, ending in dummy. You then lead dummy's last spade towards your hand. If North ruffs with the Jack, you will discard your diamond loser. If he does not ruff, you will score the ♥7 'en passant'.

Q: 5 - What will you lead against 4♠?

South	West	North	East

A: ♥A. You need look no further than the ace of hearts. Take the East cards now and see if you can make the spade game.

♣ A Q 6 3

After cashing the ♥A K, South switches to a trump. How will you play, as East?

You draw trumps and finesse the ♦Q successfully. You then return to your hand with another trump and finesse the ♦J. When you cash the ♦A, South follows with a deceptive ♦K.

It may seem that North has the top diamond now, but it costs you nothing to lead the ♦5. When North shows out, you discard a club. South wins and has to return a club into your tenace, or give you a ruff-and-discard.
