Commentary by Ryo Maeda 6P
Game Recorded by Chris Burg
Published in the American Go E-Journal

“This is a really interesting and exciting game,” says Ryo Maeda 6P in his game commentary, “with many mysterious and interesting moves.” The game features a non-joseki variation that winds up being an even trade and then a ladder plays a critical role in the fighting that follows, with an attack on Black’s central group, more ladders and finishing with a nailbiting semeai with just one period of overtime left.
