1 = Negative double: 4-card ©-suit, or, 12+ hcp, or,
both.
2 = North treats South's negative double as a 1-over-1 response. This is not
a reverse.
3 = South made a negative double first, so this forces game, and designates § as trump suit.
4 = ¨-control (must be ¨A).
5 = ©-control.
6 = §-control (must be §A), denying ª-control.
7 = RKCB.
8 = 0 or 3 out of 6 aces (1403-variation).
9 = Asking for queen of trumps.
10 = Promises §Q, denies outside aces.
South upgrades his ª-holdings, but he does not
need the marked ª-finesse to make his 12
tricks: he can ruff 2 diamonds in hand.

1 = One round force, 5-11 hcp, unlikely to have 3-card ©-support, denying 4-card ©-support and 4-card ª-suit.
2 = East is too strong for a jump rebid of 3ª,
that would only promise 16-17 hcp. So far, we included 6331-hands in this 3NT-rebid as
well, This board proves however, that East must be kind of balanced. If he holds a
6331-hand, he should rebid 3 of his best minor. That way, West will know when to sign off
in 4©, and when to end in 4ª.
3 = West can have several sorts of distribution for his forcing 1NT-response. For his
rebid 4©, he must have at least a 6-card ©-suit. Since East has promised 2 or 3 hearts for his
rebid of 3NT, West's hand will probably more valuable in 4© than in 4ª.
4 = In a sound partnership, East has no reason to question West's judgment.
More discussion to follow.

1 = Muiderberg weak-2: 5-card ©-suit, 4+ of a minor, 5-10 hcp. South should 2 top
honors in hearts, and a 5-card §-suit for a vulnerable
Muiderberger.
2 = 5+ ª-suit, 12-15 hcp.
3 = At imps, East must bid game, even when it could be a close
one.
More discussion to follow.

1 = North's hand is too weak for a vulnerable simple overcall, and his clubs are too
bad for a vulnerable preemptive overcall.
2 = White versus red, this hand would qualify for a weak jump overcall of 2ª, even when both opponents have bid. Vulnerable,
South should have better spades: ªKQxxxx, ªAJTxxx, or better.
3 = We would still stay out of the bidding at this vulnerability.
4 = West has shown a minimum opening hand, so East must forget about slam with his 'ugly'
balanced hand.
More discussion to follow.
