end-games with active Play-button

[jsm3520]

Thank you for providing the handviewer tool, with which I am very pleased.

 

I am planning to use it in a course on card play, and unfortunately I

have encountered a problem, hopefully caused by my not being familiar

enough with the tool. If not, consider this a suggestion for modification.

 

Setting up an end game situation, i.e. with less than 13 cards in each

hand, the Play-button fails to let me control the play. The

situation is set up with an a-argument, as for instance a=-sd to have

south play with diamond as trump. Clicking 'Play' then does not

indicate player's position with the usual yellow marking and

consistently does not allow a card to be picked.

 

Of course I can arrive at the desired situation by playing from trick 1,

but only in the minority of cases is that relevant and tolerable.

Usually I want to focus on the interesting situation. A guide to a proper

way of using handviewer will be appreciated.

 

If the problem requires a serious programmatic effort to resolve, it

might help with an additional parameter to spool over a given number of

tricks or card plays or start at an indicated trick number. It will require

an additional effort by an author, but at least provides a usable fix. It

will be more convenient for viewers.
