75 moves FIDE-rule in section 9.6b

[Norbert Raimund Leisner]

Hello,

50-move rule: 5.2e. A player may claim a draw if the last 50 moves have been completed by each player without the movement of any pawn and without any capture.

75-move rule: 9.6b. The game is drawn if the last 75 moves have been completed by each player without the movement of any pawn and without any capture.

Will be an implementation of the (mandatory?!)75 moves-rule from the year 2014 into modern graphical user interfaces like Arena, Scid vs. PC, WinBoard etc or is this a redundant provision?

Best wishes,
Norbert

No. The 75 moves rules is only for arbiters in Human chess who are forced to declare a draw after the opponents missed to declare it
for various reasons.

If the last move resulted in checkmate, that shall take precedence.
> 75 moves rule

[Norbert Raimund Leisner]

the same position has appeared, as in 9.2b, for at least five consecutive alternate moves by each player. > rule 9.6a

WinBoard / XBoard offers the possibility (sice 2008) to have the GUI make draw adjudications after a configurable number of reversible moves or repeats. For FIDE Chess you can set this to 75 and 5, respectively, in the Adjudication Options dialog. It will always accept engine draw claims after 50 moves or 3rd repetition, no matter what the adjudication setting is.
