-## TODO

-### NEXT STEPS
-
-### IMPORTANT
-- memory: plan for total memory release (pool, etc...) to please valgrind.
-    - not so easy: need to keep track of allocated blocks, **and** to understand that no object is in use.
-- move.c, piece.c: function to remove an element from list.
-- position.c: duplicate fully a position (including board & piece list)
-    - should move list be duplicated ?
-
-### MISC
-- `move_gen()`: `doit` is maybe redundant with test on current turn.
-- should board be included in position ?
