黑：依田紀基 白：夏衔誉

白52 妙手! 白 can tighten black corner liberties with A. Plus after white joins at B white can save three triangle white seeds with K4.

黑53 extended the liberties but 依田老师 might have overlooked 白66 pull out. 白72 concludes this battle: white has a possible force out at A and overall white has a good lead on black.

If black cuts at 黑67 then white can 白68 and 白70 captures 4 black seeds.

白78 force out is very severe. Variation to 白96 is 一本道. After 白96, black finds it very difficult to escape outward. Black's first instinct is to jump at A.

After black jumps out, 白98 removes black group's eye. If black forces to capture white seeds with 黑99 then 白100-108 black crumbles.

Actual game. After 白102, white still can run at A to capture black seeds.

Overall the game was difficult for me in the opening. I was fortunate that 依田老师 had crucial misread in the lower right battle. I was able to close out the game in the end.
