A little something on Black 69 as well...
In the game Black answered

with

. Then when White played

, Black answered again with

. This was a very poor play. The reason is that

is in the wrong direction and has almost no meaning. The key point is that the two marked stones on the left prevent White from doing anything significant around here. Locally Black should play

at "a", limiting White's potential along the right side. On the board as a whole, Black should still go ahead and hane at "b" since it is still the key point overall.

So I just re-read your last comment regarding black 69. You mentioned white 68 is in the "wrong direction" but I don't quite get what you mean by that. Could you explain a little further regarding that? Thanks!
When White plays

below (68 in the game), let's assume that Black plays at

(instead of 3 as in the game), that White continues with

and Black ignores it to play

. Now the question is what can White do with the combo of 1 and 3?
- Black's stones on the bottom side are much too strong for White to successfully attack. So what other way might White try to use 1 and 3?
- The space to the left is quite narrow and Black's marked stones are also strong here. If White plays something like

, he can make a few points between 3 and 5. However, something like

will limit what White can gain there while also further reducing White's potential points around the left-side white stones. Also the points that White can make around 1 and 3 are less than the reduction in potential points on the right side by Black playing at 2. Does this make sense? Can you follow my explanation?
