Scoring: IMP

---

Hello, this is the twenty-first thread in the big poll. Please provide the most probable result after East opens 1♠ and you either

a) pass
b) double
c) bid 2♥.

Please do a cross imp result like:

a-b:
a-c:
b-c:

(a-c means the imps a wins over c)

Thanks :) Please try to do all 30 hands also :)

a: 2♥=, 110
b: 3♣=, 110
c: 2♥=, 110

flat board

[awm]

a: 1♠-P-2♠-3♣-P-3♥-All pass. Down one, -100.
b: 1♠-X-2♠-3♠-P-3NT. Making on a spade lead, +600.
c: 1♠-2♥-2♠-3♣-P-3♦-P-3♥-All pass. Down one, -100.

a-b = -12 IMPs (-700)
a-c = 0 IMPs
b-c = 12 IMPs (700)

The double improves north's hand substantially, to the degree where he can force game opposite a spade card since the clubs are a huge trick source. On the other auctions, north does not know about a club fit and his hand is a lot worse opposite a fairly likely singleton from partner.

I wouldn't be as agreesive as adam, I think 3♣ playing lebenshol is enough with north's hand althou its close.

A: 3♣ +110
B: 3♣ +110
C: 3♥ -100

A - B = 0 IMPs
A - C = 5 IMPs
B - C = 5 IMPs

[Codo]

A 1♠ pass 2♠ 3♣ pass 3 NT -1 -100
or 1♠ pass 2♠ pass pass 2 NT pass 3 ♣ pass 3 ♦ pass 4♣ -1

B 1♠ X leads to 3 NT -1

C 1♠ 2♥ 2♠ all pass? -1 + 50

AB 0
AC -4 imps
BC -4 imps

[shyams]

agree with awm on a and b
For c., I'd guess that if the sequence begins as awm said
i.e. (1S) 2H (2S) 3C; (P) 3D (P) now North could try 3S and reach 3NT again.

a-b = (12) IMPs (-700) to N/S
a-c = (12) IMPs (-700) to N/S
b-c = 0 IMPs (---)

1♠-p-2♠-3♣
p-p:(

+130

1♠-x-2♠-3♠

1♠-2♥-2♠-3♣
pass

+130

ab -10
ac 0
bc +10

Codo how do you go down in 3NT? are you some kind of a magician?

[jdonn]

Agree with awm's auctions.

a-b: -12
a-c: 0
b-c: +12

Jack playing 2001 BWS on championship setting says:

a 3cn= 110
b 4cn-1 -100
c 3se-1 50

a-b 7
a-c 2
b-c -6

[Dirk Kuijt]

I end in 3♣ a lot

a
1♠-p-2♠-3♣
p-p-p

b
1♠-X-2♠-3♣
p-p-p

c
1♠-2♥-2♠-3♣
p-p-p

flat at +110

The questionable one to me is b; is 3♣ adequate over a double?
