7. Both sides keep checking the other is a draw. ("Resolve check and check back" is a draw.) (See example in Diagram 4)

Diagram 4: Red moves first
R5+1 c6=5
R5=4 c5=6
R4=5 c6=5
R5=4 c5=6
R4=5 ...

Red's moves of R are "Resolve check and check back". So is Black's moves of c. If both sides repeat the same moves, it is a draw.
