Hmm, yeah, I think we are talking past each other.
Everything you describe is just pattern recognition to me. Lookahead or search does not depend on the broadness of the motive.
Lookahead, to me, is the ability to look ahead and see what is there. It allows very high certainty even for never before seen mating combinations.
If the line is forcing enough it allows finding very deep combinations (which you will never ever find with pattern recognition because the combinatorial explosions means that basically every deep combination has never been seen before).
In humans, it is clearly different from pattern recognition. Humans can see multi-move patterns in a glance. The example in the post I would play instantly in every blitz game. I would check the conditions of the pattern, but I wouldn’t have to “look ahead”.
Humans consider future moves even when intuitively assessing positions. “This should be winning, because I still have x,y and z in the position”. But actually calculating is clearly different because it is effortful. You have to force yourself to do it (or at least I usually have to). You manipulate the position sequentially in your mind and see what could happen. This allows you to see many things that you couldn’t predict from your past experience in similar positions
I didn’t want to get hung up on whether there is a crisp boundary. Maybe you are right and you just keep generalising and generalising until there is a search algo in the limit. I very much doubt this is where the ability of humans to calculate ahead comes from. In transformers? Who knows.
