- #nodes ("acn"): into standard statistics (sum_stats)
- special function to heuristically compute mate indicator for a move,
  use in SAN-cvt, to avoid move execution ("may be mate move").
  Do normal/capt & prom. No ep or castling.
- input: split z-command into "tom" and "depth"
- input: command for -x and/or solv_lost
- -W: width info, all struct/union/typedef; cnt.c?
- -VV: version info: all config manifests.
- chest.c: better solution list printing: numbered, SAN-like (no #)
- chest.c: negated options (undo)
- autodetect PGN input; infile.epd; also at parsing time.

- cost: simulate realistic usage & profile "cost" implementations

- LDF_ACOV_TAB(bauer): split white/black?
- LDF_ACOV_TAB(bauer): extra table for promotion?

- name semantic dirs (up/down/etc)
- bau_lrbeat[C][2]
- bp->b_fig  is unused ?  make cond?
- SET1: for different types
- Makro for testing a single bit
- Loop-Macros for PieceSet-Enumeration
- Loop-Macros for Piece-Enumeration of one colour

- mate2: implement E1DATT
- mate2: collect computations around moving piece
- short-cut trc_move_{exec,undo}: lay somewhat open the conditions.
- make canonic names for init-funcs

? fig_adirs[Figure] -> uint16: bit test statt switch(F)

- check small signed types (f_pos64): should probably be unsigned
  + check signedness
  + make typedef & abstraction

- make automatic move generator test-suite: try against trivially correct prg.
- construct benchmark mixes with different characteristics
- tell XIC success of analysis (result).
- make better "cnt" module: line#, sorted, names, quotients.

- answer heuristic: move farthest B first (support later promotion)
- snooping: try more snooping? also in 3-mate? get data
- experiment: when to start to push promotion
- make probabilistic PLM generator, derive typical statistics from it

- statistic for: attacker is mate/stalemate (and cannot solve)
  ? per depth (like mvx counter)
- when -t: print analysis results (& reasons ?)
- extended statistics for material balance

  + [#wB] [#wS] [#wT] ...
  + [Kombi wBSLTD], jeweils ob >0 (Werte 0..31)
  + Doppel-Kombi?
