Here is an interesting bidding problem that my computer program to generate
bridge hands generated.  You can be playing matchpoints or imps or even
(gasp) rubber bridge, it doesn't matter.  All that matters is that you are
vulnerable.  East is dealer and there is no competition in the bidding.
The object of the game is to devise a reasonable and justifiable bidding
sequence that gets you to a reasonable 7D slam given these two hands:

			North

		  S: 6
		  H: AK762
		  D: 9632
		  C: J52

			South
	
		  S: AKT73
		  H: Q43
		  D: AKQT7
		  C:

Good luck and may you see more difficult hands in tournaments.

South	West	North	East
1S [1]	PASS	1NT	PASS
3D [2]	PASS	4D [3]	PASS
5C [4]	PASS	5H [5]	PASS
6D [6]	PASS	PASS	PASS

1	Prepared opening to allow 3d rebid.  Proves I got at least five spades
	which can be useful in a preempt situation.
2	Follows the spade opening, forcing is a bit rich, but I will do it
	against many except perhaps Kehala and Murray.
3	Any partner that bids hearts is no partner of mine.  I woud never jump
	with three suits covered and he still might get a chance to bid hearts.
4	This is a why not bid, with partner sounding so week, it is not likely
	to happen normally, but the slam needs one of the partners to be
	agressive.
5	The hand is golden now, and is worth a bit more vigour.
6	6 diamonds is enough, with two suits in danger of a loser, a grand is
	probably 75%, exuberance is touched with caution.

This is actually from friend Martin Schafer, not me:


 South	West	North	East
 1c[1]	Pass	1h[2]	Pass
 1s	pass	1nt	pass
 2d	pass	3d	pass
 3s[3]	pass	4h[4]	pass
 4s[5]	pass	5h[6]	pass
 7d[7]	pass	pass	pass

1	17+ HCP
2	Positive response, natural
3	Agreeing on suit, showing ace of spades
4	Showing ace of hearts
5	Showing king of spades
6	Showing king of hearts
7	With the heart suit running and partner probably having
	four diamonds, it is very unlikely that we have any spade
	losers and most possible hands should have a play for seven.

	The tricky part is: partnership agreement must be that the
	2d 3d sequence, after the strong club with a positive response,
	DOES delclare suit.  This is not too unreasonable.

How about this Romex sequence:
2C [1]	pass	2S [2]	pass
3D [3]	pass	4S [4]	pass
5C [5]	pass	5D [6]	pass
7D [7]	pass	pass	pass

1. Hand with less than 4 losers and 5 or more controls
2. Control showing response: 3 controls
3. first natural bid: diamond suit
4. splinter: fixing diamonds as trumps
5. control asking bid
6. answer: none in clubs
7. you have exactly the right 3 controls
