Eingorn has a book on this stuff which seems interesting. "decision making at the chess board".
but in general it sounds to me like you could just work on strategy in general, i.e. less obvious positional goals like creating weak squares / pawns or creating a situation where you can use a colour complex strategy etc.
you have a million times more experience in chess than me, i've only been playing somewhat seriously since august, so you can take my advice with a grain of salt i guess.
I have been playing chess on and off for twenty years and I still find myself playing moves that in hindsight make no sense. This is usually in positions where there are no forcing continuations and no obvious positional goals like putting rooks on open files or occupying an outpost.
I have been looking for books or articles online that address the fundamental issue of choosing a move but theres a lot of convoluted, confusing and sometimes contradictory advice about this topic.
Kotov's ideas in Think Like a Grandmaster just don't seem practical in quiet, closed positions. Although its the famous 'Kotov Syndrome' I am actually trying to break. Thats where you flit around from one variation to another in a half assed way and then play something that you barely considered because you couldn't see a clear continuation in any of the other lines. Silmans ideas don't cater for the many positions where there is more than one 'imbalance' in play. Dan Heisman's move choice algorithm is not focused enough etc. etc.
I haven't read Soltis' 'How To Choose a Move' book which obviously has exactly the title I am looking for but I am not sure if he provides a simple formula or just goes into the usual 'take into account all of the positional elements and create a list of candidate moves' discussion which creates the mental fog in the first place.
