R2-1 ....

Explanation:
Red keeps checking. Either Red ckecks with one piece or with several pieces, it violates the rule and has to change to other moves. Otherwise, it will be ruled a loss.

R4=5 k5=6
R5=4 k6=5
R4=5 k5=6
R5=4 ...

Explanation:
Red keeps checking. Either Red ckecks with one piece or with several pieces, it violates the rule and has to change to other moves. Otherwise, it will be ruled a loss.


Diagram 3:Red moves

R4+1 k4+1
R5=6 k4=5
R6=5 k5=4
R4-1 k4-1
R4+1 ....

Explanation:
In the above 3 diagrams, Red keeps checking. Either Red ckecks with one piece or with several pieces, it violates the rule and has to change to other moves. Otherwise, it will be ruled a loss.
