Sixteen-year-old Calvin Sun narrowly edged out 17-year-old Bill Lin to become the American Go Association’s third pro Monday night. Sun eked out a 1.5-point win in an exciting nearly 300-move final – forced by Lin’s second-round win earlier in the day — that kept hundreds of fans on KGS guessing until the very end. Sun topped a tough field of eight strong players in the second AGA Pro Qualification Tournament and joins Andy Liu 1P and Gansheng Shi 1P – who won the 2012 edition — as the first homegrown U.S. professional go players. Ryan Li won the Exhibition League. Click here for pairings, results and game records.

Myungwan Kim 9P served as referee and provided live game commentary on KGS (available free under KGS Plus/Recent Lectures) for the two final rounds. The event was hosted by the historic Hotel Normandie in downtown Los Angeles. photo by Dennis Wheeler
