Suppose that, as a result of White's move, there have now been 100 single-moves (50 full moves) since the most recent pawn move or capture. White didn't claim a draw because they're going for the win. Every option for Black's next move is a pawn move or a capture. Does this mean that Black has now lost the opportunity to claim a draw under the 50-move rule?
(Art. 9.3 of FIDE's Laws of Chess (2018) suggests that they have, but I wanted to check. If I've understood correctly, the opportunity does not just occur on the 100th non-pawn non-capture and then vanish forever --- you may claim at any point from the 100th onwards in a series of more than 100 --- but there must be a series of at least 100 including the very turn in which you make your claim. That is, retrospective claims do not stand.)
This question was prompted by my reading up on Art. 9.3 of FIDE's Laws of Chess (2018) to respond to this question.
