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 PDN Grammars) 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


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.
