Join us for a very special opportunity. On Saturday, October 20 our chess teacher Jonathan Torres has invited Master International level chess champion Mark Machín Rivera to our library. Mark will offer a chess workshop at 10 am. The suggested donation for the class is $5.00. Mark has represented Puerto Rico in international chess tournaments in Russia, Turkey, Norway, and Azerbaiyán, among others. The class is for children and adults, ages 8 and up. Questions? Please contact Jonathan Torres at 787-455-1546. ​
