Session 5, Boards 09-16

Recommended bidding sequence:

1 = Jacoby Transfer, promising 5 or more spades and 0 or more hcp.
2 = Asking South to pass with doubleton of spades, but to but 4ª with 3-5 spades.
3 = Event though his pattern is 3433, South better corrects to 4ª.

More discussion to follow.

Recommended bidding sequence:

1 = We usually pass 11 hcp hands, unless we have a 5/4 pattern or better. This thime, the 'straight flush' in ¨ makes up for the one hcp missing.
2 = With a good 5-card suit and 8 hcp, South must take some action. NS probably have a slight majority of hcp.

More discussion to follow.

Recommended bidding sequence:

1 = Muiderberg weak-2 openings with a 6-card major are not permitted, and considered technically inferior, as well. We would treat this hand as a weak-2 in ª either, for that could very well misinform partner.
2 = One of several types of strong hands. In our system, we don't add weak hands to this opening bid. We feel, we have done enough preemptive bidding with our multi 2¨ and Muiderberg weak-2 openings.
3 = West must respond 2¨, unless he has a good 5-card suit and 8 or more hcp. West must give East the chance to describe his hand first.
4 = In our system: semiforcing or better, with © and a second suit.
5 = 5⁺ suit, 5⁺ hcp, forces game.With only 4-card suits, or a very weak hand,West would have to bid 2NT now.
6 = Designates spades as trumps, demands West to start cuebidding sequence.
7 = With all suits controlled, West skips cuebidding, and starts asking for aces.
8 = 1 or 4 out of 5 aces, since we play 1403-variation of Roman KeyCard Blackwood.
9 = Asking for queen of trumps.
10 = Should show 3 outside kings, for in our variation, developed by 1987 junior world champions Jan Jansma and Rob van Wel:
         a. 5© = ªQ and ©K, or, ªQ, §K and ¨K
         b. 5ª = no queen of spades
         c. 5NT = ªQ, but no outside kings
         d. 6§ = ªQ and §K, or, ªQ, ¨K and ©K
         e. 6¨ = ªQ and ¨K, or, ªQ, ©K and §K.

11 = With all aces and kings, the queen of trumps, and at least 9 spades between EW, East should be able to make overtricks!

If West ruffs a §, his trick taking potential rises to 16!

Recommended bidding sequence:

1 = Stayman relay. South may or may not have a 4-card major, so North must alert.
2 = West should wait (again), for South may be strong. West does not give NS the option of doubling for penalties, when they find game too close.
3 = For this response, North may still have a 5-card ©-suit, or 4© and 4ª.
4 = South now shows 4-4 in the majors and a hand too weak to try for game. He may have up to 7 hcp though.
5 = At imps, it's is unwise to bid 3¨. If South happens to have 6-7 hcp, he could still double for penalties, grasping for the bonus, NS could not bring in on their own.

More discussion to follow.

Recommended bidding sequence:

1 = One round force, promising 5-11 hcp, but virtually denying 3-card ª-support.
2 = 2§ and 2© would not be forcing, and 3© would not be flexible enough.
3 = South must be careful. If he bids 3¨, West will have to bid 3© with a 4-card ©-suit, but with interest in 3NT as well. 3© is still Fourth Suit Forcing, since South's 1NT-response was not real in the sense, that he wanted to play NT.

More discussion to follow.

Recommended bidding sequence:

1 = North may be bypassing a 4-, 5- or 6-card ¨-suit (Walsh approach), so South must alert.
2 = Ordinary reverse, 16-19 hcp, one round force.
3 = North is not strong enough for 2©, for opposite a reverse bid, Fourth Suit should force to game. A jump rebid of 3ª would force game, as well.
4 = 2NT would show 16-17 hcp, and therefore be an underbid.
5 = South must have a spade for his bidding. North's hand will be of little value in 3NT.

More discussion to follow.

Recommended bidding sequence:

1 = One round force, showing several types of hands with 5-11 hcp, but virtually denying 3-card ª-support.
2 = Promises at least 6 spades. If South has only a 5-card ª-suit, he should look for another rebid, occasionnaly 2§ or 2¨ on a 3-card suit (2§ with 5323 and 5233, 2¨ with 5332).
3 = 6-card suit, less than 2 spades, and 10-11 hcp. South could still have some ©-fit and 14-15 hcp.
4 = Minimum hand.

More discussion to follow.

Recommended bidding sequence:

1 = Should be o.k. at favorable vulnerability.
2 = Promises 5-card suit, for with only 4 spades, East makes the negative double.
3 = Support double, showing exactly 3-card ©-support and 6 or more hcp.
4 = Support redouble, showing precisely 3-card ª-support, and 11 or more hcp.
5 = Unwise to allow EW to play 1ª redoubled, which to are most likely to make.
6 = East has some hcp strength to spare, so 2ª should be playable opposite a minimum West.

Jansma and Westerhof prefer the cuebid over the support double. Perhaps, they treat the double in 1§-1©-1ª as responsive. We would not find that a logical approach, for only diamonds have not been bid yet, so South might just as well bid 2¨, when he has them. We would not find it a good idea to treat West's clubs as unreal, even when the convention card of EW says 2⁺.

More discussion to follow.
