Seizoensopening 2018-19

De seizoensopening had dit jaar wat anarchistische trekjes omdat ongeveer de helft van de aanwezigen de voorkeur aan het gewende zaterdagsvluggerrondje gaven in plaats van de geplande onderlinge teamwedstrijden. Niets mis mee, er waren genoeg leden en gasten aanwezig voor beide activiteiten. Een gezellige schaakmiddag met zo'n 30 deelnemers als smaakmaker voor het aanstaande seizoen.
