“In the original form of the five-fold occurrence rule, the repetitions had to occur in consecutive four move blocks (one move by each player away from the repeated position and then one move by each player to return to the repeated position). The Laws of Chess have removed that restriction, but the restriction remains in the US Chess rules.”
We should update the US Chess rule here to match the FIDE rule.
Why do we need to align ourselves with every FIDE rule? If we do need to match align ourselves with FIDE rules, why do we need a separate rule book? This is the U.S.A., speak English, or, when in Rome, do as the Romans do!!!
Who proposed that we align ourselves with every FIDE rule? For the FIDE rules that make more sense than US Chess rules, as is the case here, we should adopt the FIDE rule.
Why, it’s all I hear every time a rule is discussed. “FIDE does it this way” “FIDE does it that way” “We should get in line with FIDE”. I don’t play in FIDE tournaments so I don’t need them, since the world revolves around me.
If we do need to match align ourselves with FIDE rules, why do we need a separate rule book? This is the U.S.A., speak English, or, when in Rome, do as the Romans do!!!
