Chapter - Solving

[Solving actually performs the action for the player.]

Understand "solve" as solving. Solving is an action applying to nothing.

Check solving when suggestion hinting is currently disallowed (this is the check whether solve is currently allowed rule):
    print IH message for suggestions-disallowed instead.

Carry out solving:
    now relevant action is the suggested action;
    unless relevant action is the action of the person asked fake-actioning:
        process appropriate action, actually performing.
