  (Asked by: username_0 on 2021-06-26)
  
  What's the term for a zugzwang position P where
  
  1. White is winning, with or without the move
  2. White's best way to win from P is to execute a tempo-losing manoeuvre which leads back to P with Black to move?
  
  Admittedly, by the strict definition of zugzwang, any position where White wins if Black has the move qualifies as "zugzwang" only if White to move can't win. So that would exclude positions satisfying criterion 1. I am thinking here of positions where having the move doesn't deny White a win -- that win just takes longer. "Zugzwang" is often used in this looser sense.
