I'm not pro enough to end up defending 1♥x ;)

 

Molybdenum Forcing Pass System:

S ---- N

P --- 1♣ (1♥) (opening hand, 0-bad 12)

dbl --- 2♠ (4+ ♠ and pretty much anything else, 6-9 points and 4 spades :blink: )

4♠ --- P (signoff)

 

 

OCP

 

1♣ - 1♦ (1♥)

2N - 3N

How do you find spades with that system?

What do those bids mean?

Unnamed Homebrew Diamond:

2♣-2♦ weak ♦ OR weak majors OR GF majors OR 20-23 bal / pass-or-correct

2N-2♦ 20-23 bal / transfer ♥

3♥-3♠ denies 4-card support / also 4 ♠

4♦-4♥ 5 or 7 CPs, agreeing ♠ / interest in slam opposite 7

5♣-5♠ second-round ♣ control / signoff as there is ♣ duplication

South has 6 CPs (1 ace and 4 kings). What would South bid over 4♥ with first round club control instead of second?

South has 6 CPs (1 ace and 4 kings). What would South bid over 4♥ with first round club control instead of second?

 

(i) we count the trump Q as a control

(ii) after establishing that we may have enough CPs for slam (11 for small, 13 for grand), we bid 2nd-round controls up the line. If duplication is found, we sign off. Obviously with 6 facing 6, for example, we can ignore the first point of duplication (K facing singleton).

(iii) I miscounted N's controls; on the actual hand he's only got 3 CPs (DA, C singleton) and would therefore sign off in 4♠

 

Let's modify the hands a little to

 

T943

JT965

AK3

9

 

AKQ8

KQ

Q974

A85

 

Here S still has 7 CPs (2 aces at 2 each, 2 kings at 1 each, trump Q at 1) and N now has 4 (A, K, singleton). The auction, from S making a slam try in S, would be:

4♦-4♥ 5 or 7 CPs, agreeing ♠/interest in slam opposite 7

5♥-6♠ Second-round ♥ control, no 2nd-round control in either minor, 7 CPs/7 facing 4, no duplication, => 11 working CPs, a fit, and hopefully enough for slam.

 

I hope this illustration is a little clearer!

Excellent description! Yes, that is much clearer. The point I am still slightly unsure of is when you say that North has 3 CPs consisting of ♦A and ♣x. First of all, that you count a singleton as 1CP and secondly if that means the ♦K is not worth anything. Finally, there is a the question as to how you find duplication opposite a void. This is certainly an interesting method though - not one I have come across before.

First off, in the original hand N has 3CPs as he doesn't have the ♦K. We count singletons as 1 CP.

 

As for voids: we also count those as singletons if responding to the slam try. We try not to make a slam try of this type when holding a void: there are many different enquiries we can make (e.g. Exclusion, etc.; on some sequences we have cue-bidding available).

 

Full system notes are available at http://www.matthew.ath.cx/misc/systemnotes.pdf - the section on this slam method is at p.34 (General Swiss). We picked it up from another player at the Cambridge Bridge Club (I think we tweaked it a bit, but I can't remember).

Thanks for this link. The write-up is very clear and the approach is interesting. It is (kind of) a little like Turbo but with CPs instead of key cards. Hopefully it will come up on a few of the upcoming hands so we can see it in action. For the strong 2-suited openings, you could take a look at Ben (inquiry)'s MisIry method if you wanted to add some extra detail/complexity to the follow-ups.
