If I start a Bidding table, and selected Dealer Source/Advanced, I can
paste code into the Dealer Source text box. If I check the box "Use
this code...", the Redeal will then deal hands to that specification.
This code:

shape(north, any 4333 + any 4423) and
hcp(north)>=15 and hcp(north) <= 17 and
(hcp(south) >= 8 and hcp(south) <= 18)

will generate a series of hands where North has a 1NT opener, and
South has varied hands that have between 11 and 18 HCP.

Googling on the web, I see that this is a subset of the input for Hans
van Staveren's Dealer program which is described at
http://www.andrew.cmu.edu/user/gc00/biddin...ler/dealer.html

My objective here is to generate a series of hands for practice on
BBO. I'm getting there slowly by trial and error.

The code above generates a 1NT opening bid. I would like to develop
similar code for all the 2 over 1 openings and responses so I can
teach a new partner who has never played bridge and practice with them

I imagine this as a long text document containing all the opening bids
and responses, from which one could cut a particular lesson and paste
it into the Dealer Source box.

My questions are whether BBO or anyone else has developed code for the
Dealer Source box to do that; and whether BBO has any documentation
for using the Dealer Source box to help in that objective. Or do I have to do this by more trial and error?

This (and the thing you use inside BBO) is backed by Dealer. The page above has links to the syntax

Thanks Uday,

However, BBO appears to only use a subset of the Dealer functionality. The pre-processor commands generate a BBO error. Try pasting:

shape{north, 5+xx5+}

I guess the message I am getting from you and from BBO Tech Support is that there is no concise guide to the Dealer syntax for Dealer Source on BBO. Given that I will have to build the scripts I want by testing by trial and error from the best available Dealer doc which so far appears to be:

http://svn.df7cb.de/debian/dealer/branches...nual/dealer.txt

[uday]

N, the msg is:

1. There are two contexts in which we use Dealer. Inside the client, and on the web page above.

2. The docs for the scripting lang can be found at the SYNTAX link that the web page (link above) cites http://www.xs4all.nl...input_file.html


I don't know if shape{north, 5+xx5+} is valid syntax or not, for this version of dealer.
My guess is that Hans' version ( the one we're using) isnt the same as the one you're referencing.


produce 5
condition spades(north) >= 5 && clubs(north) >=5
action printoneline

seems to work just fine. Anyway, check the docs.

Thanks Uday.

The code you gave was:

produce 5
condition spades(north) >= 5 && clubs(north) >=5
action printoneline

In the BBO environment only this line is needed:

spades(north) >= 5 && clubs(north) >=5

The curly bracket stuff came from a Dealer pre-processor I found.

My mild beef continues to be that I can't tell where BBO differs from Hans' spec. He allows variables e.g. BALANCEDHAND = shape(north, any 4333) and conditional logic in the ternary operator to use those variables. BBO apparently does not allow variables nor logic.

Variables work for me.

The dealer input:

balhand=shape(south, any 4333)
balhand

and redeal


Logic example:

balhand=shape(south, any 4333)
hcpsouth=hcp(south)>22
balhand and hcpsouth

and redeal

Thanks Walter,

That works for me too.

The ternary operator too.

No problem.

I was wondering who you referred as Walter, and then I realized... "I am the Walrus"
