I want to get a feel for the opening. Can you tell me the knack of erasing a moyo before the opponent sets it up?

answer
Hello, Mr. Warada.

A feel for the opening is important. If you miss the vital point, you will fall behind at one blow.
The important thing in the opening is to occupy large points. It’s difficult to explain the knack of reducing a moyo. If you get impatient, you reduce too early, which just makes the opponent thick, so in most cases you don’t profit.

The strategy I recommend, that is, the strategy I like, is to lull the opponent into a false sense of security, then plunge in. While the opponent is happily enclosing territory, I try to take the largest points first, then invade his moyo just before it’s completed. This is disagreeable for the opponent, as it’s surprisingly difficult to capture groups.

Of course, there’s a risk of suddenly dying, but I like the thrill and excitement. If you want to enjoy the thrill of victory, I think this is the best strategy.

Please forgive me if my answer is not very helpful.
