Hi: Perhaps I should not say a word as much I am not programmer, but as a long time user of many programs and besides with some inclination to put my nose where I am not called to be, let me say you this: According my experience, the great asset human still has over computer is a altoguether different conception of future. For chess programs "future" is a definite extension of time translated as a anumber of plies. Distant future is, say, how the board will or could be in ply 14 from now on. For humans, future is an indefinite entity without numbers asociated. A good player knows or guess something good will be got in a king attack without knowing for certain "when" it will happen. So his strategical evaluation of actual moves can be and in fact are very fussy, but in such a way has a potential grasp of hidden and obscure posibilities lurking in the current position. Even if the human does not see the specific outcome of a move, - no score. as the program- he can dare to think something will happens with it "because" of the potentials of that unknown future. The computer does not see things that way. This move is worth such specific score according the code, nothing more, and his value has to do with position reached at the end of the chain of positions searched. If values for assesing strategical considerations could change according previous game history and not only to position, sometimes giving more or less value to the same move because the game is going to a different path...well, perhaps that it could give a more flexible undesradning of future, planning, etc. Just my half of a cent.
