I think the issue is that something like this is so specific to the game that there isn't too much you can put in a general article. People are free to prove me wrong, but it seems very difficult.
General stuff I can think of:
Endgame Pile Control (I am awful at this. Primarily matters in engine games. I feel decent in my 3-pile control, but not in choosing good Victory card buys.)
Deciding when to counter a strategy or let it do its thing (Alt-VP is the main concern here)
Figuring out transitions that depend on the opponent (for instance, in games with a decent engine and an attack, you have to choose between getting the attack early and building up, then getting the attack, and both have merits. Attack first slows down your buildup, but slows down their buildup too. Build up -> get attack might take longer to set up, but if you start playing your attack almost every turn, it can catch up.)
