3.

 

Reason: it is very likely pard has a singleton club, thus he rates to be unbalanced with 5 diamonds. That makes our hand magical and we should convey that message right away. Unless RHO is joking, we probably have a slam here. In fact, if I could only make one bid here, it would be SIX DIAMONDS.

I think expecting game here is bonkers

 

Are we expecting partner to not have a 4432 or 4441 or 3451 or 4450 12 count?

 

3C might not be game forcing, but what will we do over 3D, which I assure you is what partner is bidding

 

I can see trying to slow the opps down from getting to 4H if they belong there, but i can't imagine doing it expecting to head to game or...slam?

How about passing 3D? I don't understand any of the apparently many points you are trying to make. What's wrong with playing 3 with an 8+card fit and two unbalanced hand? Why can you guarantee that partner is going to bid 3?

(I would also suggest that we do expect partner not to have 4432 shape, given that LHO bid 2 and we have 6 clubs.)

I made a instinctive quick pass when RHO bid 2, wich happens whenever RHO bids my suit. I regret it 4-5 seconds later but was too late.

 

LHO bid 2 as expected, but it was passed to me back

 

Stuck with no bid, I tried a stupid double to show my penalty double hand then wich got a lucky +300 instead of the deserved -570, partner having Axxx xxxx AK10xx -

Would love to defend 2 x'd. That isn't going to happen.

 

We might as well raise diamonds now via 3. I don't know if LHO is going to bid hearts or make a responsive double, but we can worry about that later.

Wow, doubling 2H is just awful. It doesn't just show a trap pass, it shows some defense against hearts. Doing it with a stiff is suicidal, and on top of that you have 4 card support for partner and an easy 3D bid which you expect to make.

 

don't we have a spade trick, a club trick, and more than just the KJxxx we'd have sat with over a reopening dbl?

I was curious about your claim and ran a sim out on 1000 hands and got this: (0-1 scale, with 1 = 100%)

 

0.075 pard has 4432

0.134 pard has 4342 or 3442

0.194 pard has 3451 or 4351

0.244 pard has 4441

0.099 pard has 4450

0.147 pard has 6 diamonds

13.159 pard average hcp

 

Since the actual hand shows us 11 hcp and a 4450 are enough for 10 tricks on any lead and 11 without a trump lead, I would say you're being VERY pessimistic in claiming we don't have a game here.

 

Sure, aroun 8% of the time pard will have the dreaded 4432 shape, but that's just about the only bad thing that can happen.

Yeah I also thought 8% was too much, but that's what the simulation yield. Here's the code:

 

produce 1000
dealer south
predeal north SK2, H2, DQ432, CA98732

ab1d = hcp(south)>10 and hcp(south)<21 and spades(south)<5 and hearts(south)<5
      and diamonds(south)>2
int  = hcp(west)>6 and clubs(west)>4 and hcp(west, clubs)>4 and 
      spades(west)<5 and hearts(west)<5

condition ab1d and int

action
average(shape(south, 4432)),
average(shape(south, xx42)),
average(shape(south, xx51)),
average(shape(south, 4441)),
average(shape(south, 4450)),
average(shape(south, xx6x)),
average(hcp(south))

average(shape(south, xx6x)),

Wow! what a clever program! Is it free ?

Should you also specify:

diamonds (south) >= clubs (south)

and

not (clubs(south) = 3 and (diamonds (south) = 3)

or something like that

That's redundant. Overcaller has 5+, partner already has 6, so we can only have 0-2. It's also specified that opener has 3+.

It's free, yes. You just write a script and plug it into this BBO page: http://www.bridgebas...aler/dealer.php

Thank you, Whereagles. Fantastic and fun! I reran your script and got similar results for partner's hand....

0.084 4432

0.131 4342 or 3442

0.208 3451 or 4351

0.257 4441

0.093 4450

0.148 xx6x

13.148 av HCP

Generated 1074099 hands

Produced 1000 hands

I was surprised by the frequency of the 4432 hand. Thanks again :) :) :) :) :)

This is interesting, I guess the reason partner is more likely than LHO to have any spare clubs is that we are (rightly) constraining partner and overcaller from having a 5 card major, therefore LHO is stuck with 3 spades and four hearts, leaving only 6 spots available for clubs. Partner only has 3 of his spaces reserved (for diamonds), so has 10 spaces available for clubs.

 

Don't know without looking at some hands how well the overcall is defined, i.e. whether overcaller would pass a lot of the simulation's 5 card club suits, and would in practice have a 6th club more often than this simulation suggests. My guess is that even though we are looking at 6 clubs, overcaller would also have 6 clubs more often than the simulation's 12% of the time.
