Round 3 of the ASCUN Nacional Clásico Femenino kicks off today in Medellin with Colombia's top female players battling through a seven-round Swiss. The 60-minute classical format with 30-second increments gives these competitors real time to calculate, not blitz tactics. After two rounds, the field remains tightly bunched.
