Go up one level in this thread


I have the idea that the core of this business is to see which sub-set of
heuristic are relevant to such or such position. To know what knowledege is
irrelevant is the key of real knowledge.
It is clear that when, as a human player, you feel that attacking the king is
the thing to do, due to the overall position, you make like Alexander Tolush did
and any master does, that is to say, you look for tactical knock out. Tolush
used a witty sentence: "I look for a way to sacrifice the queen; if I do not
find one, then and only then I look for more quiescent moves...."
If you smell a mate attack against black it would be silly to expend time
considering the positional outcome of playing a3.
But on the contrary, if you does not see nothing in the realm of king side
attacks, the thing to do is becoming positional and not calculate sacrifices and
wild attacks.
Every seasoned chess player do more or less that.
I suppose Rybka do that.
I believe it has some kind of monitoring set of codes lines to decide if going
for tactics of keeping positional.
If not, perhaps it should has  :-)

My best
