A new way to present problems

[Fluffy]

I've been wanting to share this hand with you several months, but it was a many part problem and no format fit.

 

So I made a webpage where you can do multi-part problems, when you pick an action another problem follows.

 

EDIT: The hand is in MPs in case it matters, gotta work for it to be shown on the page.

 

Hand I played in October

 

DOES NOT WORK WITH INTERNET EXPLORER on versions below 9, use a decent browser like firefox or chrome.

I'd like to be able to embed this thing on the forums, maybe when I'm done with all the stuff that's left (quite a LOT of things) I will work on that.

 

But right now, please try the hand and share with us your score, don't be ashamed, a world master on your shoes got the worst possible score so you will be in good company.

The link doesn't work for me.

Edit: I use internet explorer 10.

sigh, I gotta work more with compatibilities :(

ALL HAIL THE BRIDGE GOD FLUFFY!!!!!!!

 

We are not worthy.

Stopped on me in Firefox, I won the A♣ v 4♥ and played a small spade back. That trick was won and then it stopped.

 

Edit: tried a different return at trick 2 and it stopped there too, giving an error when I attempted to retry.

[ahydra]

I managed to play the whole hand out but every spade symbol (including on the cards) was shown as a question mark in a box. (Edit: Firefox 20)

 

I must have missed the point of the hand though. I bid 1C to start, then 1H-1S-p; 2S-X-p-3H; p-4H and out. CJ lead to the A and K, SA and spade back, declarer ruffed, drew trumps and gave me the DA. Looks pretty cold given the DJ drops in two rounds.

 

(Edit: unless that's the point. Win the DA and play another one back straight away, declarer has to guess? Or even underlead the DA at trick two?)

I tried this on my office computer (running Internet Explorer 9) and it did not work. When I get home, I will try it on Google Chrome.

[diana_eva]

Stopped in Chrome too. I got as far as trick 4. After I ran out of trump I could not discard any suit.

 

Also took me a good 5 minutes to figure out how to bid and where to look to see the bidding. The rectangle at bottom left where it says 1c - 1h - 1s confused me.

It worked fine in Opera. There seemed to be two valid defensive solutions.

complaints about site´s name to be delivered to richard pavlicek, who was the one to suggest the nick... http://www.rpbridge.net/7x96.htm

 

Its sad that so many problems are arising, I think play stopping will be because ajax is failing at some point for too many conections and the hand doesn´t load, I never saw before requests timing out, but will I change it when I´m back tonight to resend requests after a timeout.

I love the site name!

Yes, the problem is flawed but the interface is on its way to being good.

[SteveMoe]

Worked on chrome just now, but wouldn't let me switch to a low Diamond after winning partner's club opening lead. Should beat 4 hearts.

Slick interface. Liked it a lot...

Nicely done Fluf! Found one little bug though: I can't play ♠9 at trick 2. When I click ♠9 it plays ♠6.

[Finch]

It seemed to work for me in Chrome.

Although after I'd beaten the contract and partner led to trick 9, it showed all four hands, and said we had 4 tricks, but still had the message "this option is not covered..." shwoing

Its not a bug, it is extremelly hard to compute all ways to play a hand, so I simplify some points by playing some pips that are equal, this hand's graph has 104 nodes if I recall correctly. When you played that pip if I wasn't lazy there should had appeared a text at the top explaing that they are almost equal or something like.

 

This was the way I planned to catter for completelly equal cards like AKQ or 987, but later on I found a way to allow any card by a transformation table, but right now I found no way for almost equal, or otherwise there would be no plan to follow if for example later on ♠8 is led from dummy and partner is suposed to allow yout ♠9 wich actually is ♠6 now.

You came close, if you want the solution, here is the full story of the hand:

Thanks, I need to remove that message when you finally click on something that works.

There seems to be a problem with my javascript code and internet explorer, I thoug once the CSS3 problem was solved IE would work, but there are more differences to account for, will need to work on that, thank you

Thanks guys, I forgot about this issue because it never failed on my own computer, but it just took a small amount of work on the server for it to start to fail. I have made a patch so that it will re-request info after some time awaiting for it, instead of waiting forever for it to come alone. So shouldn't happen again.

I sat there clicking on 2S in irritation, because I thought that was our first decision. Also generally found it an eyebleedingly awful interface: screen cluttered and with an advertisement on it, played cards hiding part of dummy, spade pips not showing, the text in a tiny little box that refused to scroll to show me the second half of it, "WesNortEastSout" bidding box labels...

 

I gather the problem is that you assume we will all have a maximized browser window at a high resolution. I seriously question the wisdom of a site being unusable in an 800x600 area.

Great idea, Fluffy :) And well done Frances and Phil for finding solutions to the problem :) It's too hard for me :(

• When RHO wins ♣A and returns a ♣, declarer can win cheaply, draw trumps and lead a ♦ to dummy's honour. If it wins, declarer can discard his losing ♠ on a ♣ winner and claim.
• But if defenders cash a ♠ before returning a ♣, then declarer will strongly suspect RHO holds ♦A, even if RHO later ducks dummy's ♦ honour.
• If defenders have cashed a ♠ earlier, it may be better to start with a top diamond from hand.

What am I missing?

You must be doing something seriously wrong on the web technical side. Your links do not work in Safari or Chrome on a Mac at 2315 USEDT.

 

Safari show the server is not responding. It is too late for me to debug this.

 

Are you running on a real server with legit DNS addressing, or your own PC with an IP address that is dynamically assigned?

Thanks for the info, if you mean the links on links section of the page, they are very simple <a href> ones, hard to imagine what would go wrong there :/

I have been working on better display for the last week, you better not know how this things looked like a week ago on smaller resolutions :P. But even tho, I know there is still a lot of wok to do there, my wife tells me the eyebleeding thing all the time, and I am looking forward to fix it. I am open for suggestions regarding background color.
