May I suggest a simple possible solution to the loophole in the FIDE Laws of Chess.
Here is the section in the rules.
9.6 If one or both of the following occur(s) then the game is drawn:
9.6 If one or both of the following occur(s) then the arbiter may declare the game drawn at his discretion:
9.6.1 the same position has appeared, as in 9.2.2 at least five times.
No change
9.6.2 any series of at least 75 moves have been made by each player without the movement of any pawn and without any capture. If the last move resulted in checkmate, that shall take precedence.
9.6.2 any series of at least 75 moves have been made by each player without the movement of any pawn and without any capture.
Last sentence in the above rule was removed, because the arbiter claims.
Now the rules are just like claimed, but claimed by the arbiter at his discretion.
For 3 fold and 50 moves a player claims, but at the players discretion.
For 5 fold and 75 moves the arbiter claims, but at the arbiters discretion.
For online play the chess website is the arbiter, they just leave the rule, in the program code, as it is, the program code (arbiter) claims the draw for 5 fold and 75 moves providing that the final position is not checkmate.
Loophole closed.
