Scoring: IMP

---

Hello, this is the eighteenth 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: 4♥-1, -100
b: idem
c: idem

flat board

[awm]

a: 1♠-P-1N-P-2♣-P-2♠-A/P. Making three, -140.
b: 1♠-X-P-3♥-P-4♥. Down one, -100.
c: 1♠-2♥-P-2♠-P-3♥-A/P. Making, +140.

a-b = -1 IMP (-40)
a-c = -7 IMPs (-280)
b-c = -6 IMPs (-240)

On the second auction, north has a decision between 2NT and 3♥. But the result is roughly the same in both contracts, assuming a pass of 2NT and a normal club lead (but a raise of 3♥ to game based on the extra trump).

[Codo]

A 1♠ pass pass 1 NT pass(?) 2♦ X 2 ♥ pass 3 ♥ ap +140
B 1♠ X pass 3♥ pass (?) 4♥ pass pass 5 ♣ X ap -25 + 500
C 1♠ 2 ♥ pass 2 ♠ 3♣ pass pass 3 ♥ ap +140

AB -360 -8
AC 0
BC +360 8

I see a lot more action here

A: p-1NT-2♣-3♥-p-4♥
B: p-3♥-4♣-p-p-X-all pass
C: p-2♠-3♣-3♥-p-4♥ anyway, north is not staying out of game.

A: -100
B: +100
C: -100

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

a.1♠-p-p-1NT
2♣-

here it depends on the methods. if it's going to be N who declares it's -200 if S then probably -100. I will say 50-50.

b.

1♠-x-p-3♥
p-4♥

this is a clear -200

c.

1♠-2♥-...
-100 or -200

ab: +1.5
ac: 0
bc: -1.5

[shyams]

a: Agree with awm. 2S by E; -140 to N/S
b: N/S reach 4H (from North side). Down 2 after a CA opening lead; -200 to N/S
c: 1S (2H) pass (2S); pass (3H) all pass; makes on a spade lead +140 to N/S

a-b = 2 IMPs (+60) to N/S
a-c = (7) IMPs (-280) to N/S
b-c = (8) IMPs (-340) to N/S

a. 1♠ p 1NT p
2♣ p 2♠ ppp
-140
b. 1♠ X p 3♥
4♣ p p p
South can always end up ruffing in when east tries to ruff a spade.
+50
c. 1♠ 2♥ p 2♠
3♣ p p 3♥
ppp
+140

On 2 east might not bid 4♣ but at this vul I feel he would. North might bid 3♥ or 1NT (not 2NT!) but 3♥ seems more normal. After the 4♣ bid I don't see why south would raise, he has an extra heart but a minimum without short spades that has seen his Qx be bid by an opponent.

a-b: -5
a-c: -7
b-c: -3
