The Furstner 2♣ Rebid - Facts
After a Opening bid, a Responder with 6-9
points (or 10 pts and 9+ losers) has only two options at his disposal :
a. raise to 2♠
with 3+card support, or
b. bid 1NT without it (Responder may not bid a new suit at the 2-level !)
Responder is forced to bid 1NT, even with a singleton or void in
♠s. Responder could also hold 4, 5 or even 6 ♥s with no means to convey this to the Opener.
With a minimum Opening hand (13-15 pts), this is usually not a
problem. Opener will either pass, bid 2♠ with a 6-card suit, or bid
a new suit at the 2-level when unbalanced.
In this last case
Responder will either pass or bid 2♠, showing preference.
However with a strong to maximum hand (16-21 pts) Opener must bid
on, for a Game contract in many cases is likely.
In such case Opener's
options too are rather limited.
He can rebid :
a 6-card suit
or (19-21) when balanced
c. a new 5-card suit at the
Opener's rebid of a suit at the 2-level will be perceived as a minimum
hand (13-15), after which Responder is not obliged to bid again.
The Furstner 2♣ rebid by the Opener (after
- 1NT → ) shows a strong hand (16-21), is forcing and asks Responder to specify his hand.
Responder's replies can then show a :
1. minimum (6-7) or maximum
2. 4-card or a 5+card ♥ suit
3. doubleton in
Opener's ♠ suit
4. minor suits distribution when holding 9+ cards in ♣ and ♦ combined
