@ TAROU: I'm not sure that I understand what you mean. I was sure that in Chinese chess perpetual check *is* absolutely prohibited (no 'almost'). A few months ago, in an OTB game against a Chinese friend, I played a move threatening mate in one that could only be avoided by giving perpetual check to *my* King, so you could well prove that I was "forcing" my opponent to give it. The perpetual was obvious, but he resigned without trying to give check even once. If it were legal to give perpetual check, he would have given it and drawn the game.

Any clarifications would be welcome, particularly from arbiters.
Thanks in advance.
