Combining Magic Diamond and MOSCITO

[Kaapo]

I've never actually played either of them, Magic or MOSCITO, but studied them. Magic Diamond's (see http://web.telia.com/~u83607584/carrot/magic.html) 1M openers as well as the transfer responses are nice; 1♣, 1♦, 2C♣ and 2♦ openers less nice. MOSCITO 2005 (pdf: http://www.australianbridge.com/moscito.pdf) seems very interesting all in all, but it takes some time and energy to study and memorize the relay structures. So I tried to combine these two in a system that I have not yet played. :)

 

It uses strong club, weak notrump and 4-card major openings together with transfer responses.

 

Opening bids:

1♣ = 15+

1♦ = 9-14, unbal, no 4cM (ie. either 54+ minors or a 6c minor)

1♥♠ = 9-14, 4+ cards, unbal or 5332, may have longer minor

1NT = 11-14, bal

2♣ = weak, both Ms

2♦ = weak, 6c M

2♥♠ = weak, 5c + 4c m

2NT = undefined (bad 3-level pre-empt or both minors maybe?)

 

Over 1 spade:

1NT = 3+ clubs, any strength (5+ cards w/o 3♠ if weak)

2♣ = 4+ diamonds, any strength (5+ cards w/o 3♠ if weak)

2♦ = 5+ hearts, any strength (no 3♠ if weak)

2♥ = 3♠, inv+ (balanced if GF)

2♠ = weak, 3-4c

2NT = 4+♠, inv+

3♣♦♥ = 6+ cards 1-suiter, GF

 

Strong jump-shifts, what on Earth?! But handling all 1-suiters (weak, invitational and GF) via xfers may be difficult.

 

Over a transfer, opener usually completes but may super-accept to show a minimum with good support or bid 2NT with a maximum and support. Of course, opener may also rebid 2M or show a second suit. Not sure if a new suit should show a maximum or not. Maybe good-bad 2NT could come in handy here (eg. bid 1♠ - 2♣; 2NT with 4♠6♣ and a min, 1♠ - 2♣; 3♣ with a max).

 

In Magic Diamond, transfer to a minor then, after opener completes, 2M shows 5m2M and searches the right part-score. But here, with a wider opening range, one may have to use this sequence with a balanced 2M443 hand of 11-12 HCP or so (in Magic these can pass because game is out of sight).

 

Responses to 1♥ are much the same, with 1♠ natural forcing for one round (usually 8+ points).

 

Over one diamond no transfers:

1♥♠ = 5+ cards, f1 (about 8+ points)

1NT = 8-11, no 5c M but something in Ms

2♣ = GF, relay (symmetric responses: 2♦ = 6+ ♣, 2H = 54+ ♣♦, 2S+ = 6+ ♦)

2♦ = invite w/o 5c M (not sure how this works)

2♥♠ = weak

2NT = both minors, not invitational

3♣♦ = weak

 

I've not thought about how to respond to stong club or one notrump, but I'm sure there are plenty of fine structures available already.

 

So anyone got a comment? Someone wanna give it a go? Or bridge, because I don't know go... <_<
