Check the US Chess Federation web site - uschess.org. Also google for local chess organizations. Even if they're not specific to your area, a state organization or something similar might have info on events near you.
It might also help if you gave more information about where you're located. The only reason I know you're in the US is that it says so under your name. Narrowing it down to what state you're in for those of us who don't recognize the name of your town might be useful.
Does anybody know where there are chess tournaments
in the watsonville or monterrey area, thanks.
