I have a question about the ground rules for tsume-shogi.  I received
the six problems kindly posted by Reijer Grimbergen, and I have found
a solution to one that involves white making a move, black responding
leaving white with no useful move to escape mate.  Black's response,
however, is not a checking move.  Is this an acceptable solution, or
must the entire sequence of black moves consists of checks ?  Thanks,
Ken.
