Hey there Siculo!
It's a pleasure to meet a fellow Long Islander! I'm from Suffolk too (around Smithtown).
The only chess club I am aware of is one that meets in the Smithtown library. I've never went, but I see their ads on public access cable every now and then. Other than that, the only chess club on LI that I am aware of meets in Nassau.
I was just wondering if there are any chess clubs around in the suffolk county area of new york? Any and all help would be appreciated.
