The Evanston Go Club hosted its Winter Wonderland tournament on Saturday, Feb 4. Turnout was excellent, with 34 players
attending, ranging in rank from 5d to 20k
“Special thanks go to Xinming Simon Guo for catching a counting error that changed the result of a game,” said TD Mark Rubenstein. Guo, the 2015 AGF Teacher of the Year and founder of the Go And Math Academy in Chicago, was video-ing the counting stage of the games. He planned to use the videos in his classes to demonstrate math concepts in the game of go.
One of the games ended with black winning by half a point. However, after the result had been entered by the TD, Guo was reviewing the 
video and noticed that there were seven black stones lined up on a row that was only six points long. “One of those stones didn’t belong there, it should have been put inside black’s territory. This is the first time I have ever seen a game result overturned based on an instant replay!” said Rubenstein.
Winners were: Na (Nicole) Pan 5d: 3-1, Daniel Puzan 2d: 5-0, William Torres Amesty 3k: 4-0, Scott Gerson 8k: 4-0, Crystal Lin 14k: 4-0, and a prize for most games played to David Rohde with 8 games. “Thanks to Yellow Mountain for providing awesome prizes!” says Rubenstein.
