If you’ve never seen one person play 10 simultaneous games of chess — and you probably haven’t — here’s your chance. Brooklyn Castle’s Justus Williams — who last year, at age 12, became the youngest African-American Chess Master ever — will hold a simultaneous exhibition, challenging up to 15 other players at once. Get there early to be among them! Players of all skill levels can get in on games, too! Great food and drink to remind you of your school days.
