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.

1 = If EW have agreed on inverted minor raises, East should use them now, in order to not complicate the auction unnecessarily:

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 = 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."
