A few more--
12. Space (may be similar but different to mobility)
13. Development (at least during opening/early middle game)
14. King Safety (individual for each side, of course)
15. Material may be a simple count, but Piece Values may change depending on the
position (sometimes Knights are better than Bishops, etc; Rooks may be
relatively stronger in the endgame than earlier).
I'd like to see the list when it is 'fully' compiled--please post, thx.
