The conflict of two sheriffs

Why this matters. When two claimants reveal themselves, two incompatible versions of the checks appear.

What to do. Draw up a table of nights and claimed checks. Compare the timeline of speeches, the votes, the moment of revealing and the line-up of the supposed black team. Do not choose by how confident a voice sounds.

How it sounds. "The first sheriff has number two as red, the second has number two as black. Let us check who played how with number two before the reveal."

Practice. Play out a dispute between two sheriffs, giving each two minutes of cross-questions.

Typical mistakes. Believing the last speaker without analysis.
