If only we did not only get scores at root or first PV leftmost node as feedback. What if we could see the whole PV used for that score.
I am also puzzled by notions of forced anything. And why should a forced sequence necessarily be the shortest. But here it is the forced notion itself. And I am putting a draft post in my musing.. instead of brainstorming here..
I think, if this is reproduced, as last 2 posts seem to confirm (I should do it myself, but seen a bunch of deep searches before and would rather rely on others curiosity by now), that we might need better understanding of what and how exhaustive search engines go from a legal tree search, with an a-priori legal mate, to ensuring the mate is actually the best alternating min-max sequence when the whole searched tree is considered.. I would like to remind all of us, that engines work with partial trees. not complete trees.
Rambling elsewhere. got tired (typing and thinking endurance). The above is summary, post removing. might try to explain while asking question later. I might also be not understanding what engines are doing there well. But who can?
