BillSpightsElfPositionalJudgmentExercises/Game 19 ELf's Solution

After W34 the Elf GoGoD commentary gives one player a winrate estimate of 88½% with 32.2k playouts. Which player is it?

It's White.

The reason that the players played the 4-4 points in the corners is not that this is from the current era, but because it is so ancient that the 4-4 opening in Japan had not yet been banished in favor of other points. It is GoGoD 1561-00-00a. Sanada Masayuki (W) vs. Sanada Nobuyuki. It may be a forgery. But I found the opening interesting. :) White won.
