Transfer opening
strong club and Forcing pass biding system
have set of limited opening
some of them have a structure of transfer opening
the idea is in general acepting the transfer is a game/try or better when the strong hand is going to be declarer

moscito have only 3 transfer opening
1♦ 4+♥ 9-14 HCP (with 2Ace and distribitution its ok to open )
1♥ 4+♠ 9-14 HCP ♠ > ♥ or equal 5=5
1♠ 4+ ♦ may have longer club
it also have 2 Natural opening
1 NT 11-14 balanced no 5 cards Major
2♣ 6+♣ no 4card ♦ in the original no 4M (now may have a bad 4card major like xxx x or J xxx

you can very long sequence
1♦ 1♥
1♠ 1 NT
2 ♣ 2♦
2♥ 2♠
2 NT ......
the first 1 describe a 4=4=1=4 with minimum value
like 3 King or 2 king and 2 Queen or 2 Ace
the J are ignored for the moment

or very short 1 like 1♦ pass
1♦ 4+ ♥ pass 5+♦ 0-2 ♥ 0-7 HCP

1♦ 4+♥ 9-14 HCP 3♥ 4+ ♥ 0-10 HCP NO GAME
IT IS NOT A LIMIT RAISE JUST TRYING TO MAKE IT HARD FOR OTHER SIDE TO COMPET

FWIW, the goal of systems like Moscito is "quick in, quick out", i.e., the emphasis with the transfer openings is get our 7(8) card major fit ASAP. Occasionally, you'll have the leisurely relay auction, but it's like 15% or less of all such openings based on memory.

Another quick note:

Modern versions of MOSCITO typically include options OTHER than relays to show hands with 4+ card support and game invitational slam invitational values.

In the version I prefer, this includes

1. A game invitational raise that shows 4+ card support and game invite+ values
2. Fit showing jumps that show a 6 card suit and 3 card support for opener's major
3. Splinter raises

The logic here is that if we have a fit for opener's major, the opponent's have a fit as well and its likely that they're going to be able to jam our relay auction. So, it's better to clarify support ASAP.

High level comment:

I think that most people now appreciate that the real value of a strong club opening isn't the 1!C opening itself, but rather that it provides the ability to make light / limited openings. In much the same way, the value of the relay responses over the constructive openings is that it enables a better constructive response structure by freeing up a lot of other bids.

.

We ditched the 3-6 fit jumps because the right hand never came up. We would do it on the wrong hands - such as a raise to two which happened to have a 6-card minor. Now we have them intermediate with no major fit. Working okay.
It allows other auctions. In particular

1♦ - 1♠
2♣ - 3 any

where 1♦ = spades, not hearts & 2♣ any balanced.
We use 3-any here as shortage, even in spades. This because hands worth 3m natural would have bid that first time.
SPlinters in partner's possible four small have proved useful.

thank you !
what do you open with ♥ ?
Fit showing jump seem to be rare .
was asking myself:
partner open 1♦ to show 4+♥ and you have 8-11 point with 4-5 ♠ and 3 cards♥
what is better biding 1 ♠ or biding 2♥ ?

was asking myself:
partner open 1♦ to show 4+♥ and you have 8-11 point with 4-5 ♠ and 3 cards♥
what is better biding 1 ♠ or biding 2♥ ?

1♣ = 16+
1♦ = 4+♠s, denies 4♥s
1♥ = 4+♥s, denies 4♠s
1♠ = majors, 4+ 4+
1NT = 12-15 no 4cM
2♣/♦ = natural, no 4cM

Thus every limit opening either shows or denies a major.
The "denied major" concept has been discarded by some other systems, like Moscito, but we value it.
