How to avoid this endplay?

This hand I played in a BBO-team-match. And I misdefended.
Click on my nick to show only my hand and dummy's.
Right-click the diagram and choose "hide played cards".

Click on "next" for every trick to see how the play went.



Do you see where I made the mistake?

After winning the diamond J it was mandatory to cash diamond A. THough partners lenght signals in the minors were wrong, I should know that declarer's distribution is 4423 and partner holds both minor Ks.

I was looking all the time for the best method to post bridge diagrams in a post.
After experimneting with different suggestions (see the below posts) I decided to make screen-shots of the BBO-Movie and post the images.
Now I found a new nice tool from Fred Gitelman: the BBO-handviewer and I'm excited.

To get a rough idea how this works:

I wrote a first example for the handviewer demonstrating how a automatic simple squeeze works. The only flaw is that you cannot set who is on lead in an incomplete deal. So I made East declarer to give South the first lead.



Try the NEXT PREVIOUS and REWIND Buttons to play the cards.
Try a right click in the diagramm to hide played cards.
Try a click on a players name (e.g. South) to see only this hand and dummy.

This is a complete hand I played in BBO, which demonstrates the necessity to agree a rescue sequence after 1NT X ven playing 15-17 NT.
