Pandanet (IGS) is hosting their second 13×13 Amateur World Go Championship. Registration is open until June 19, see http://www.pandanet.co.jp/event/13ro_tournament/2nd/index_e.htm for official details. The only requirement to play is having a Pandanet ID, with confirmed rank if you want to enter one of the two classes that use handicap. Entry to the main class does not require a confirmed rank.
I entered the tournament last year and enjoyed it. The format is very relaxed, at least for the preliminary rounds. Players have approximately two weeks to complete at least six 13×13 games in their class room. The games can be played at any convenient time and against anyone available in the room, so the time commitment to complete the required games is very low. Players aiming to make the final rounds should be warned that they may find the time commitment much higher. The preliminary results from last year show that a number of competitors played over 40 games, and one player had 68 wins to just 3 losses. Points are computed by “wins / played + wins * 0.02” so while the ratio of wins to losses has the most significant impact on results, there is a benefit to players who have completed more games.
Overall, I enjoyed the flexible preliminary round structure, the opportunity to enter an international tournament, and the chance to apply my understanding of Go to a smaller board.
