When did the 3-fold repetition and 50-move rule come about? The
1954 Reinfeld book "How to be a winner at chess" gives perpetual
check, but not these two rules. Of course, with 3-fold rule, the
perpetual check rule is not needed (also you don't have to judge
whether or not a position is perpetual check). The 1970 book by
Harkness has these two rules, but not perpetual check. So did they
replace perpetual check between 1954 and 1970?

Winter dates threefold repetition to London 1883:

The problem is Reinfeld was not a tournament official. Perpetual check
has been claimed to be a draw for a long time. The rule never existed.
The only time a perpetual check is a draw is by 3 time repetition.
Many players know some of the rules but not the exact rule.
Reading rulebooks by non TD's can be a source of entertainment (if
your a Tournament Director)
