During the second day of the TCGA Conference in the National Dong Hwa University, Hualien, Taiwan on June 30 and July 1, 2012 three blitz computer-go tournaments were organized, viz. 13x13 (7 participants), 9x9 (9 participants), and 19x19 (8 participants). The fast time settings made it possible to complete the tournaments in time and the quadruple round-robin format made the competition fair. Moreover, the large number of games led to accurate scores. The only drawback for the fast time settings was the time-consuming administrative work required to prevent halting problems. Twice, a short interruption happened during these tournaments. A second issue was the network lag. Depending on geographic locations, different lags appeared. For example, Japan had an average of 3ms lag connecting to the KGS in U.S. However, the lag became worse during the weekend. As a result, the bots needed to play faster than the tournament time settings. Even so, AYA ran out of time for several games in the 13x13 tournament. Furthermore, on July 1, the KGS experienced a serious Internet lag. It ruined the 19x19 tournament. Only the first 10 rounds were completed. All participants agreed that a new 19x19 tournament should be scheduled on July 15. Moreover, the time setting was changed because most participants complained that one round of 45 minutes was too slow for the machines’ capabilities.
