Boston Spring Open 2016

As another not-so-evil company was(is) trying to spoil the fun of face-to-face (human-to-human) Go playing, Microsoft engaged to the community and generously provided the venue for Boston Spring Open 2016 Go Tournament at Microsoft New England R&D (NERD) Center.

The tournament was held on Saturday, 3/19/2016, with 54 players plus dozens of Go enthusiasts as observers.

We used echo-friendly drone technology to setup life-death problems:

[Technology fine prints:] Next time we will use 12 inch instead of 9 inch balloons eco-friendly drones, otherwise they don’t float well with half-A4-size problems attached.

A Ph.D candidate in Physics major from MIT concluded that the more difficult the problem is, the more weight it will have, hence the balloon will fly lower. Many players agreed to her theory.

During the break of already intensive 4 rounds of playing, people tried to solve these problems. Yes, it’s a test of your brain’s stamina.

But kids have infinite energy so they were able to occupy the answering machine (a live, pizza-eating 6d) for the most of the time.

We had many strong players, including Jie Liang 7d, and Andy Liu 1p:

Finally I just want to showoff the nice Go sets we have:

The tournament had the format of fixed-banding, all-even games, with Swiss-MacMahon pairing with initial score as your entering rank. Banding was determined before the game by the TD manually.

(My explanation of why we use this system.)

We had 5 bands this time. Top 3 of each band were given cash prize. All registration fees went to prize (54 players, $20 each).


Band 1 (5d+):

1st: Andy Liu (1p), $150
2nd: Jie Liang (7d), $120
3nd: DH Yun (5d), $90

Band 2 (1d-4d):

1st: Ruoshi Sun (4d), $120
2nd: Matthew Hershberger (4d), $90
3nd: William Luff (4d), $60

Band 3 (4k-1k):

1st: Jason McGibbon (1k), $90
2nd: Cam Wagner (2k), $60
3nd: Shawn Ligocki (1k), $ 30

Band 4 (7k-4k):

1st: Wu Yang-H (4k), $70
2nd: Chi-Hse Tang (5k), $50
3nd: Eva Casey (5k), $30

Band 5 (9k-, handicapped):

1st: Cel Kulasekaran (9k), $60
2nd: Mark Nahabedian (12k), $40
3nd: Kevin Huang (12k), $20


 

The final cross-table and standing is attached here. I will post the games to AGA shortly (be prepared, this week they have NJ Open too, so it may not get reflected online soon).

  1. Just a question.
    I wonder why DH Yun (3 wins and 1 loss) is 3rd place and Jie Liang (2 wins and 2 loss). Is it misprint? Also it looks Yun beat Liang on the final game.

    1. yes. I explained this to Dr Yun during the tournament too. The reason is that we didn’t have Dr Yun’s initial ranking and he entered as 5d. Jie Liang entered as 7d. So that they have 2 points difference in the initial MMS score. The pairing algorithm ensures that same MMS score gets paired so players entering with high ranks will likely play stronger players from the beginning. Dr. Yun’s is very strong but since he only entered with initial ranking of 5, it was not enough to raise his MMS score even after many good wins. We don’t look at inter-person result, we just sort by scores(see table), as described in AGA official documents.

  2. Okay, I see. I guess the same applies for Kan Yao. He is also 3 wins and 1 loss. Though, the question remains to me this method is fair for the open tournament. I’ve never seen any game the loser awarded better than the winner.
