Six clubs is excellent since without a trump lead, East's diamonds can be ruffed in West's hand. With a trump lead there are still many excellent chances for 12 tricks. After 1-2
, what should West rebid? Playing 2/1 GF, I recommend West rebids 2
--I am a big believer in bidding out the shape. There are no "reverses" by opener in a 2/1 GF auction. East can repeat his 6-card suit, and West now has a dilemma. Should he blow past 3NT by raising to 4
? Should he punt with 3
? Will East ever move towards slam if worried about diamonds? This is a tough one.

The key to this deal is West's diamond void and the perfect fit. After 1--Pass--1
--(3
), what should East do? Presumably he has to pass (even playing Support doubles through 3
, East would need extra values for such an action). When 3
comes back around to West he can bid 3
(clearly forcing). I prefer this to 4
, which doesn't say as much about his hand. After 3
, East will bid 3
. Now, West will likely control-bid 4
(bidding 4
to support clubs and show the shape might also make sense). East can now bid 4
to show something there. Okay, so how do you reach 7
? Maybe after East's 3
, West bids 5
(Exclusion Keycard Blackwood). Even with that convention, West still needs to find out about the
K and
Q. Congratulations to any pair who can intelligently reach 7
.

What is South doing? I suppose he has KJ10853 and maybe didn't want to preempt the first time since he had spades on the side. No doubt, your auction started: Pass--1
--Pass--2
--3
. It is hard for West to resist bidding 3
. If he passes instead (maybe a reasonable idea with such ugly clubs for offense), East might double. In a 2/1 auction, all doubles should be penalty. This is a rare exception to "all low-level doubles are NOT penalty." If East doubles 3
, West will be delighted to sit. The penalty rates to be more than the value of the heart game. It is easy to see East-West getting too high. A heart slam is not a good proposition (especially with bad splits likely).

What a misfit! Can anyone stay low? If West opens 1 it is impossible to stay out of game. West might open an eccentric 2
and if East passes, a great result is achieved. This problem is probably unfair, but it comes from the Becker Archives (as do most of these problems). I am not selectively weeding out the crazy ones--such as this. I will be shocked if anyone scores 40 out of 40 on this set.
