.

here is the farmer's hat, an empty triangle of a very heavy kind. This is rarely a good play.
Black will have a pincer stone at one of the points a to f. With a close pincer (a or b) White now usually connects solidly at p, with the aim of extending to the marked point. With the more distant pincers d and e White makes the trumpet connection at q for better shape (the other two pincers are rare in this pattern).
