Here are the first 52 moves. Go was White, of course. It is hard to believe at this stage that he would win by 88, though subtle cracks had already appeared despite some good moves by Black (17, 31, 33).
19 was better at 24, 41 at 42, and 51 at the left of 38 (to settle himself). And though 43 was a shape move, it should have been one line higher. Good shape is bad? Well even ikken-tobi can be bad. Like 19, Black 55 here missed the mark. The right move is on the next page.
