ANSWER:
The short answer is just show up at our Club on Monday nights, register and pay the $10 + HST drop-in fee at our front desk (in the Great Hall), and then go play chess in our casual section (usually the Sun and Star Rooms). The larger Sun Room is great for social chat/banter while playing. The smaller Star Room is for those who want more quiet. Players of all ages are welcome.
All equipment is provided including a clock, should you want to play a timed game. Scoresheets are also provided in case you want to record your game moves for analysis later at home. We also supply free bottled water, and coffee can be purchased for $0.50. Ratings don’t matter in the casual section and players play whomever they want.
Casual memberships are available. There are approximately 40 nights per year to play casual chess at ACC, so a casual membership often makes sense.
Players are free to play classical, rapid, blitz or variants. (Ever try 4-player individual or team chess on a single board?)

Our casual section is generally set up for 12-20 casual players per evening. Sometimes, we might even do an unrated rapid game ladder for the evening. A few times each year, your casual membership or nightly fee might score you a rapid or blitz simul game against one of our titled club members or even a visiting IM or GM.
You’ll often see our ACC Casual Chess Ambassador and ACC Board member, Michael Sutton, hanging out in the Sun and Star Rooms on a Monday evening. He can assist and even start you off with a casual game or two, and maybe even a quick lesson if you’re new to the game.
Finally, casual chess is great for helping seniors maintain their brain health and socialization skills and to just get out and have some fun. It's a low stress activity and relatively inexpensive.
