1 = When partner has opened at the 1-level, and RHO overcalls at the 2-level, a new
suit at the 3-level shows 5+ cards in the suit, and 12+ hcp.
2 = Competitive double, showing 3+ ©-support and invitaional strength or better. West
has left us no room for support doubles, which are used just to
show 3+ support, and can be made on weaker hands as well. The raise to 3© has to take care of these types of hands now.
3 = 7+ suit, signoff. If East has strength to justify a slamtry, he should bid
3ª. Remember, West has already forced us to
game.

What would 3§ mean in an auction like this?
2 = Just showing a ©-stopper. If West can rebid
4+ suits only, EW will not be able to get to 3NT properly. West can't bid 2NT
or 3NT yet, since he is not sure §K contributes
to stopping clubs. Of course, East must alert responses in
majors that (may) have nothing to do with an attempt of looking for a playable fit in that
particular major.
3 = Invitational, showing stoppers in the black suits.
4 = After East's 2NT, West should still slightly downgrade his stiff king, but he finds
enough compensation in his extra ª-stopper and §-length.
3NT will fail if South has the §A, and North
starts out with king and ten of hearts.

1 = Modern bridge strongly tends to wait with showing 3-card support, unless responder
is weak. In our system, 2 over 1 to a major forces game.
2 = Even when NS do not treat 2 over 1 to a major as forcing to game, they have at least
23 hcp between them. That makes East's clubs too shaky to overcall with at the level of
three. Especially in a team game, East does not want to provide NS with a lucrative
penalty double as an alternative for a game that may not make. Muller and Verhees are
certainly aware of the risks they take, but would never recommend others to follow
their lead.
3 = Since North has forced game already, South could even hold 19 hcp for this rebid.
4 = Showing 3-card ª-support and 12-15 hcp.
5 = South has not nearly the strength to explore for slam.
Even without East's help, West will lead §T,
top of doubleton in the unbid suit, for the queen. Declarer should knock out ¨A, while limiting his ª-losers to two. His best shot is, to start with ¨K, which East must duck, and ¨Q. East wins and returns a low ©
for the ace. Now, South leads towards ªA,
catching East's stiff Jack, and dumps a © on ¨J. West may ruff, but after that, he will only get
his king of trumps. If he discards a §, South
pitches his last ©-loser, crosses with ©K, leads a low ª
from hand, and again, two trump tricks are all West gets.
If East, after winning ¨A, returns his last ¨, South will dump a ©. West ruffs, and leads another §
for the ace. South cashes ªA, crosses to hand
in hearts, and lays down a low spade. Now, West can't keep South from dumping his
remaining ©-loser on a good ¨ of dummy.
Westerhof also led ¨
to the king, but when Verhees allowed him to keep it, he
erroneously called for a low spade from dummy, after which he could no longer avoid 3
trump losers, and a 10 imp swing to Onstein.
Ramondt succesfully finessed with ªQ, and then led ¨K. Muller
decided to take immediately, after which defense was over already. Ramondt
was lucky not to find East with a stiff ªK.
Therefore, Jean-Marc Roudinesco in his Dictionary of
Suit Combinations, recommends to cash ªA, and lead
to the nine next.
For purpose of review, Bridgesoft
sent us copies of both GIB 4 and Eindeloos (' Infinite')
Bridge 6+ from their headquarters at Bussum,
The Netherlands. Both programs go wrong on the play. GIB, in
trick 2, ducks a low spade to East's Jack. EB6+ starts out very
well with ¨K, ¨Q for the ace, ©A, and ªA, but then, unfortunately, leads ªQ from dummy twice.

1 = Multi Landy: 6+ suit in one of the majors.
2 = Asking North to pass, or to correct to 2ª,
depending on his 6+ suit.
3 = West has given his partner a pretty accurate picture of his hand, so he should leave
any decision to him.

is definitely worth mentioning.

1 = We adhere Walsh approach: bypassing a 4-, 5- or even
6-card ¨-suit when responder has less than 12
hcp. East must alert.
2 = When both opponents have bid, North's ¨-suit
is too bad to overcall with.
3 = Invitational, showing a balanced hand and exactly 11 hcp. 2ª would promise more, and force game.
4 = 6-card suit, minimum hand (good 11 to bad 13 hcp).

1 = Forcing for one round in our system, promising any of several distributions, and
5-11 hcp.
2 = With 5323 or 5233, West should rebid 2§
rather than 2ª.
3 = False preference. East is uncertain about Wests §-length,
and a 5/2 fit usually plays better than a 4/3 fit.

1 = We do not open 11 hcp hands in first or second chair, unless we have a 6-card suit
or some 5/4 hand.
2 = We open 4§ and 4© with solid 8-card majors, but no aces or kings in side suits.
Therefore, we use 3NT to show hands others would open natural 4§ or 4¨ with. To our
opinion, North's hand does not qualify for such opening in first or second chair.
3 = Vulnerable, South should certainly take action, for in that event, North must have at
least ¨AQxxxxx or ¨AJTxxxx, and some scattered values. Not vulnerable, North is too
likely to have preempted on trash.
After the ª-lead, EW cannot keep North from
making 11 tricks. When East or West shifts to a club in trick two, declarer calls for the
ace, ruffs a ª in hand, runs ©J, leads towards ©Q,
dumps his §-loser on ©A, and yields a ¨ to
the ace.
In order to hold North to 10 tricks, East must start out with a §, or lead ¨A and shift
to a §. Former junior world champion Rob
van Wel keeps saying: "Don't make things more complicated than they
are, just lead your longest suit, unless you have sound reason to do something else."
