A quadruple check is possible in shangxi
How to triple check
OK., guys, let's move on and get serious about "real Chess". Good. Now was that hard? I mean, really? In my Chess club, anybody talking about "triple check" would be fined. End of story-mic drop.
I agree that we need to stay on real chess, but I disagree on "fining" anyone. There's nothing wrong about taking some hindsight to just consider whether some very particular case might make it possible. - - Although we now have figured out there is no such case.
Also see this thread.
In xiangqi, the knight's movement is restricted by a piece placed in front of it in the direction that it wants to move to. If that was the case in chess, a triple check would be possible if e8=N+++ was played in the following position.
How is the knight even placed there
One of the problems I have been working on in my free time is trying to solve the fact that any k-uple checkbelow the nth-uple check in an n dimensional board is feasable! For example, if we extend the 2D board we have to a 3D one, a triple check is possible, just like a double check and a normal check. This might apply for 4D chess and nD chess in general!! It's a pretty exiting idea. You just have to know how to formulate the rules of chess in a n-dimensional board higher than the second order. I won't go into further detail here 😉

This is impossible in this position because before the promotion, the black king is already in check.
Did you not read what he wrote? He was talking about xiangqi rules, where the knight would not check the king because the pawn was in the way.
In shangxi. Pawns cannot promote
also there are no queens in xiangqi
