This solid connection is technically correct, because it gives White two ko-threats only (, ).

If Black played at instead, White would have three ko-threats in this area (, , ).

White tries to take advantage of Black's cutting points in the upper left corner, when playing this hane on the first line.

Quite surprisingly (at least for our amateurish eyes) Black answers with a move in the nakade, so following a suggestion of Michael Redmond. This move forces White to take Black's stones in the nakade off the board, to avoid a seki.

Black will lose a point, if he connects at , instead, as we did before.

It will not benefit White to throw-in at , instead.

White wins by one point.

However, if Black did not play any throw-in in the hanezeki, White would have two prisoners less, so loosing the game by one point.
