BTW, how about expanding this code to allow a GAME-code-specified text to appear in the move entry field, in the case it 'auto-selects'?

You can add additional legal moves to the $extralegal array, and these will show up in autocomplete.

One way to achieve this would be to allow the GAME code to do setlegal 0 " @-"; to append a fake move to the $legalmoves array, which would be passed to the JavaScript as [0, " @-"].

This is what the $extramoves array is for. So, there is no need to do it by modifying the setlegal command. Furthermore, "@-" is not a complete move, because it does not specify any coordinate.

It might be possible to come up with a way of allowing non-standard moves with the mouse, which would require more complexity in the movePiece() function and the legalMoves array. But this has to be thought through more, and I need to consider what I might do with JavaScript or HTML5. Let's think about what types of non-standard moves there are and how these could be entered by clicking the board with a mouse.
