Flag falls when reached 34 move quickplay finish

[Jonathan Livingstone]

Thanks Andy, yes it was an analogue clock and white did not play their 35th move.

What happened was after black completed their 34th move, they noticed their flag had fallen and immediately owned up saying "och my flag has fallen". So there was no dispute, although nobody seemed to know what the actual rules were in this scenario.

Black later wondered if the flag fall may have irrelevant and if they could have just played on, which prompted me to find out.
