Hi:
The statement that 'You cannot put the opponent in check more than 3 times
in a row with the same piece without either side moving any other piece' is
incorrect. Rather than the number of checks being limited, it's the number
of repeating 'cycles' (which is three cycles, or a triple-repetition, which
in most cases, six checks).
This common misconception seems to stem from Lau's book, Chinese Chess. We
would be glad to discuss with you further on this issue. My e-mail is
