================== PDN 3.1 Proposals ================== This section describes proposals for the next version of the PDN standard. Alternative move disambiguation ------------------------------- The current way of move disambiguation (see section :ref:`grammar-section`) was chosen for backward compatibility. The following alternative is proposed. An ambiguous move is written as usual, followed by the sequence of captured squares between angular brackets ``<`` and ``>``. For example, in the following position .. image:: diagram1.png the two possible captures are written as ``47x36 <42, 29, 14, 31>`` and ``47x36 <42, 29, 19, 31>``. The motivation for this is that it is less complicated to implement, and easy to understand for humans.
