1♦ = 5+♦ unbalanced 11-23 HCP. 2 exceptions: 4-4-4-1, 5 ♦-3-3-2 (17 -19 + HCP)
If 5♦-4 ♥-2-2 or 5 ♦-4 ♣-2-2 little concentrated open 1 ♣ or 1NT.
The 2 ♦, 2 ♥ and 2 ♠ auctions made without intervention to show a two-suiter 5 ♠-4 + ♥ are no longer relevant.
2 ♠ bid retains the meaning given to it after opening 1 ♣ and intervention to the one
level.
Namely 6+ ♣ weak or 5+ ♣ GF. Similarly TRANSFERT for the other
major shows 6+cards, weak or GF.
This
is great for playing clubs or other major from the good hand (the opener one).
And
for the memory : after the opening of a minor and intervention to the one level, 2 ♠ bid always
shows 6+ ♣ weak or 5+ ♣ GF and the TRANSFERT for a major shows 6+cards, weak or
GF.
And after opening 1 ♦ the 'remaining bid at the 2 level shows 6+ cards in the other major and a limit hand.
Which give :
X = 4-5
♠ or 6+ misfit
cards.
1 ♠ =
4+ ♣ . Maximum 10 HCP.
1NT = Natural. Probably not Fitte.
2 ♣ = 11+ HCP. Natural Denies 4+♠ . Holds 6+♣ limit.
or ♦ support 10+HCP.
2 ♦ = 6+♠ limit.
2 ♥ = 6+♠ weak or FM .
2 ♠ = 6+♣ weak or 5+♣ GF (4+♠ possible).
3m = Unchanged.
3M = SPLINTER (heart SPLINTER is unlimited)
Purpose: To affirm immediately spades and play from the right hand. Play clubs in the right hand with ambitions.
All this, in the minds of developments after an overcall on 1 ♣ .
