Scientific Test, Part VII: Conclusion

Target Feature Count (TFC) may be a useful element of a move search heuristic. This has been a preliminary test. Further examinations are needed to answer the following questions:
  1. What is the best method to separate significant from non-significant targets?
  2. Is the TFC score useful for ranking targets or only for candidate target selection?
  3. How can positional features be added to the TFC list?
  4. How can target features be weighted?
  5. What is the significance of TFC in the opening, in the middlegame and in the endgame?
  6. Are the number of targets and their TFC scores different in open, semi-open and closed games?
  7. Is TFC useful in quiet, positional situations?
  8. What is the typical life of a target? When does it emerge? How long does it live? When does it disappear?
  9. How many significant targets are present in typical situations of a game, and how do they score in TFC?
  10. How can TFC be optimized for use in practical games? What amount of time is required? How can TFC be done under time pressure?

The question of the lifespan of a target is interesting. What makes a target emerge, what makes it disappear. When you start with TFC before move one, the effect of every move should be shown clearly.

That's exactly what I plan to do. Just one example. Before move one, there are no targets with TFC 3 and more ( I use this value as a threshold). After 1.e4, there are two targets: e4=4 and f7=4, but after 1.d4 there is only the target d4=4. Interestingly TFC reveals a difference between open and closed games. This is one of the subjects for my further examinations.
