"the sheer number of possible positions" ++ There are 10^44 legal chess positions,
of which 10^37 without promotions to pieces not previously captured.
Of these 10^17 are relevant to weakly solving chess, as Schaeffer did for Checkers.
"calculate every potential outcome" ++ It is not necessary to calculate everything:
weakly solving chess only needs 1 black reply to all reasonable white moves.
I think that if you would pause and think for yourself for a moment, you would realise that in order to find that one black reply to each move by white, it is necessary to investigate very thoroughly quite a large number of black replies to every white move. I mentioned five candidate moves earlier (a couple of weeks since) but I also mentioned that to do the job properly, maybe nine candidate moves would suffice. That would be your "weak solution".
Here the quotation marks are appropriate, since the term is being used incorrectly by @tygxc, based it seems on his lack of understanding of the nature of the solution of checkers.
A weak solution strategy for white requires a response to EVERY legal move by black. None may be ignored, even if Steinitz didn't like them. That's the DEFINITION of a weak solution.
(I did think that they looked like things that elroch would attempt to present as facts. You sure you're not "working together"?)
