3NT = 4+ ©-support, balanced
hand, 12-15 hcp. The extra heart, the doubletons, the kings, and the guarded
queen more than make up for the one missing hcp. 3¨,
the Bergen replacement of the balanced limit raise, would be an underbid, since West wants
to put East at least in 4©.
4§ = First or second round control of clubs.
4ª = First or second round control of spades.
4NT = RKCB.
5§ = 1 or 4 out of 5 aces, the so-called
1403-variation.
If West has §A instead §KQ, 6© is an excellent
contract: the odds of the trumps breaking 2-1 are 78%, and if East guesses right on which
top honor to play first, he can handle a 3-0 split as well. If our EW pair bids the slam
indeed, it will win 11 imps in 89%, and lose 10 imps in 11% of the time. If West, like in
this case, has §KQ instead of §A, our EW pair will break even in 89%, and lose 10
imps in 11% of the time.
If we consider West's chances of having either §A
or §KQ equal, the slamtry will score even in
44.5%, lose 10 imps in 11%, and gain 11 imps in 44.5% of the time. So the slam is
definitely worth a try.
More analysis to follow.

1NT = North's hearts are not nearly good enough to allow South's double to stand.
2¨ = No reason for a strong takeout double.
West was unable to respond, so he is unlikely to hold more than 5 hcp.

3§ = Short suit game try.
3© = A short suit trial
is not asking for a minimum or maximum of hcp count, but whether or not East has wasted
values in West's short suit. The doubleton of clubs leaves West little room for ruffs, and
the three small cards in North's ¨-suit
indicate, that West will lose 2-3 tricks in the minors only. Since West is most unlikely
to have more than 15 hcp, he rates to have 1-2 losers in the majors as well.

Dbl = Showing exactly 3-card ¨-support.
3¨ = Short suit game try.
4© = North can afford a wasted hcp in the enemy
suit, since he brings an ace, a king, and a singleton as well.
