this is Perpetual Chase. red fouled.

Perpetual Check, Chasing, and Repetition are a complicated topic in Xiangqi, and from previous research there doesn't seem to be a universally accepted number of times used.

Our rules page should cover the implementation on PlayStrategy: playstrategy.org/variant/xiangqi
This forum post covers the last update we did to these rules: playstrategy.org/forum/playstrategy-feedback/xiangqi-repetition-and-insufficient-material-rule-updates

In the example game given, the end position was repeated 4 times, and so both players were given the opportunity to claim a draw (as stated in Additional Rules, point 4). One of the players chose to do this. I don't think Stockfish would do this, so I believe it is the opponent.
