Hi,

my opinion: don´t hash the king. Put other results of pawn eval in your
pawn-hash. For example a queen-/kingside pawnshield information, a bitarray with
passed-pawns, a bitarray with open/half-open lines, knowledge about backward
pawns, ...
Then combine these information with the piece (king) positions.

You need these pawn information for interaction with many other pieces, not only
the king.
Examples:
passed pawns should be protected by rooks from behind.
rooks should be placed on open lines or half open lines with backward pawns.
a blocked passed pawn is less valuable.
a centered piece protected by pawns wich could not be attacked by enemy-pawns is
strong.
...

Greeting Volker
