1 = To our opinion, Muller underbids with 2§, while Verhees does not
do justice to East's shape with 2NT. Our second choice would be 3¨, or even 3NT, promising a 6+ suit and 18-19 hcp.
2 = Fourth Suit Forcing may not work out here, for after 3©-4¨, 4© sounds more like a control bid with ¨ as trumps, then as an attempt to let East choose
between 4© and 4ª. Secondly, 4© does not
sound as a slamtry.
3 = East clearly has preference for hearts.

1 = This hand is too nice to preempt with. There can still be game for EW, even though
East passed in first chair.
2 = No inverted minor raises after RHO gets in.
3 = Asking West to pass if he has some sort of ª-fit.
4 = Clubs will play better, for East is unlikely to have a goos 6+ suit in ª.

1 = South's ©-suit does not qualify for a Muiderberg
weak-2.
2 = West's opening cuts North off the bidding.
3 = East lacks the 4-card support, needed for a Bergen raise to
3§, which also promises a balanced hand and 7-9
hcp.
4 = Short suit game try.
5 = West's singleton or void hits East's best suit, so East should sign off.
Westerhof overcalled 2ª
with 2NT, prepared to bid to 3¨, if Jansen
would show §-preference. In the matchpoints
pairs competition of South Limburg district, class 1 of 1998, one player took the same
action with better red suits. His spontaneous action turned out to be the only way to get
to an excellent 4©-contract, but found nu mercy
in the eyes of the director, who awarded him a severe penalty for 'screwing up the
auction'.

1 = We recommend vulnerable Muiderbergers only on a good
5-card major, and a 5+ minor.
2 = North would bid 2¨ (5+ suit,
8-11 hcp) without 3-card ©-support.
3 = Support double: 3-card ª-suit,
unlimited strength, forcing to 2ª.
4 = Competitive redouble: 3H would only be an attempt to win the
battle for partscore, so South must come up with something else to invite to game.
5 = North would be very happy to play 2©**.
6 = North is on top of his previous bidding.

1 = Jansen and Maas favor 1NT,
thereby following a recommendation of Acol 2000 by Schipperheyn
and Sint, and Five Card Majors Western
Style by Max Hardy, for example. We however, do
not like to horse around with distribution, unless we are forced to do so.
2 = The 6-card ©-suit should come first.
3 = We don't favor inverted minors in competition, but 3¨ would be preemptive anyway, since East can cue or
bid 2NT to show a better hand. North may still hold as little as 3 diamonds, and 3NT may
still be there. Two good reasons not to raise to the level of four.
4 = West should be cautious, for is unaware of the double fit, that would be exposed if
North opens 1NT and East overcalls a Landy type of 2§.
5 = Competitive double, as introduced on previous board. North
has lots of strength to spare.
6 = East has no strength to spare, he actually had a minimum
overcall.
7 = South has not the strength to pass for penalties, or accept game by bidding 3NT or 5¨.

1 = In Walsh approach, West denies a 4-card major, unless he
has enough to reverse with. This time, West is strong enough to reverse, but that alone
does not guarantee a 4-card major.
2 = Should show the unbid suits, regardless of the 2-suited weapon used when RHO has
opened (Ghestem, Top & Bottom, or Michaels).
The Unusual 1NT, used by Jansen,
serves the same purpose, but leaves South guessing for his shorter minor, which Maas
seems to show with the cuebid. We would cuebid 2¨
with a shorter ¨-suit, and would expect Maas
to join us.
3 = We prefer to use this double to show a good or longer §-suit, but we could make a case for a support double
for West's diamonds as well.
4 = Giving clear ©-preference. A (support)
redouble should show 3-card support for both
majors.
5 = Investigating 3NT by asking for a ©-stopper,
for the one West holds, will not be enough.
6 = North majors are just about even, so he should allow South to decide which suit to
lead against 3NT and 5§,
and therefore skip the double of a suit, EW are not going to play anyway.
7 = Denying the ©-stopper, but still reaching
for game in clubs.
8 = Though North's cuebid of 2§ greatly
increases the chance of an unfavorable §-break,
West has no alternative but to accept the invitation, unless EW have agreed on doubling to
show a good 5-card suit, and 3§ to show a good
6-card suit.
Game zone does not allow too much for subtleties. By jumping to 3© as South, Ramondt smartly denied De
Boer the opportunity of becoming subtle at all, or should De
Boer have doubled to ask for a ©-stopper? In the closed room, Jansma
deprives himself of chances to get subtle, offered to him by Westerhof
and us.

1 = Slightly too strong to overcall 1ª.
2 = North's takeout double would give East even more reasons to bypass a 4-, 5- or even
6-card ¨-suit in favor of search for a fit in a
major.
3 = South should be glad East's 1©-response
relieves him of the obligation to keep the auction going.
4 = East's 1©-response forces him to bid. 1NT
requires a ª-stopper, 2¨ requires at least 16 hcp.
5 = North faces the conseuqences of his initial takeout double.
6 = Attempt to deny NS the partscore. A (competitive) double
would show 3+ §-support and be
invitational or better.
