Night statics and dynamics

What to do. Statics is a fixed order of targets. Dynamics is an agreed change of target, set in advance, on a permitted condition. Make clear which signal is unambiguous, who gives it and what to do in case of doubt. Do not use forbidden communication.

How it sounds. If condition A is met, the second target is number 8. If not, number 4 stays. If the signal is unclear, we use the original statics.

Exercise. Play ten practice nights; estimate the percentage of matches of the three black players on the target.
