1 = Reverse: 5+ §, 4+ ¨, 16-19 hcp.
2 = Still Fourth Suit Forcing.
3 = 2NT would show a 2245-hand with 16-17 hcp, giving West the option of passing out below
game.
4 = No reason to make East choose between 4©
and 4ª. If East held a 3-card ©-suit, his second rebid
would have been 3©, and if he held a 4-card ©-suit, his first rebid
would rather have been 2© than 2¨.

1 = Muiderberg weak-2: 5-card ª-suit, 4+
of a minor, 5-10 hcp.
2 = An overcall of 3© would only promise a 5+
suit and 12-15 hcp.
3 = West's hand does not qualify for a preemptive raise. With his partner only holding five
spades, this would be asking for a bottom score.
4 = A 3©-response leaves no room for
exploration, and 3§ may be the only contract
that makes.
5 = 3© would just show a 5+ suit and
16-17 hcp, and not force West to bid again. 4©
is more than likely the right spot, even when North shows op with a singleton in ©.
6 = North should not get excited, for South would have cuebid 3ª with a 20+ hand.

1 = South lacks the singleton to make a semi-preemptive jump to game. He confines with
a limit raise.
2 = Fighting for partscore. If West wants to invite to 4ª,
he should make a support or competitive double.
We have little room for misunderstanding here, for a penalty double
is most unlikely to be profitable in a situation, where South invites to game in North's
suit.
3 = At matchpoints: at least a queen short of accepting the invitation.
4 = East should only bid game if his overcall was based on a 6-card suit and 14-15 hcp, or
a hand of similar strength.

1 = East's hand does not qualify for an overcall that shows 2 suits. His spades or much
better than his ¨. As matter of fact, he can
hardly afford to overcall at the 1-level at this vulnerability, as we shall see.
2 = South smartly passes, hoping that North reopens with a double, which he would be happy
to transform into a penalty double. Experts call this a trap pass,
or trapping.
3 = No reason to run yet.
4 = A re-opening double is appropriate, unless North has a freak
hand.
5 = East must wait and see for now.
6 = South recognizes the happy hour.
7 = SOS. With a singleton in East's suit, but support for all of
the other suits, West should scramble, his best shot to save at least some
matchpoints. Unlike at imps, EW have got nothing left to lose.
8 = North has to wait. South may be (and actually is) able of doubling clubs for penalties
as well.
9 = Now, South has to wait and see.
10 = Hoping East has just bid a 5-card suit.
11 = Unwise to bid, for West is most likely to have a 4-card ©-suit, while South's preference to trap 1ª does not sound very promising about his ©-support.
