What advice is there for judging a first Nexus Night event, particularly regarding when to give warnings?

Ruling: At Nexus Night (low OPL), the most important thing is to correct mistakes and keep play moving. Punishments should be reserved for serious problems or nefarious intent, not minor errors.

Sequence:

• When called over, slow down and listen first
• Take in the relevant information
• Understand the line of play that did happen
• Determine how it should have happened
• Correct the mistake and keep play moving

Nuances:

• Nexus Night is low OPL, so the approach should be more educational than punitive
• Focus on correcting mistakes rather than issuing warnings for minor infractions
