Vital point
Key point (for either player), in either the local, or, perhaps less commonly, the global context[1]. Not be confused with urgent point.
This Hikaru no Go web site offers the following explanation (loosely rendered).
A point that maximizes the effectiveness of the stones. Similar to tesuji or best move, but with a different nuance. A tesuji is a strong move within the context of a sequence of moves, but if you occupy a vital point, it's hard for the opponent to gain a good result no matter where he plays. Of course, the two are not completely distinct.
Example 1
is a vital point for shape.
From Jowa, Powerful Fighter (Gohwan Jowa) by Takagi Shoichi, p. 60.
Example 3
Below are examples from TournamentGo1992, page 152 (left column) and page 154 (right column). They are taken from the game record and commentary from the game Otake Hideo (White) vs Kobayashi Koichi (Black), 30 September and 1 October 1992, the third game of the 17th Meijin Title. [1]

From Tournament Go 1992, Figure 4, page 154
Takemiya is quoted as saying "Black 61 (). As mentioned above, this is the vital point, the key point of the whole board." Here is is using the term in the sense of Tennouzan.

[1] Question: Is this the same as the "crucial point"?
Bill: Crucial point is not go jargon. So who knows, but probably not, or the author would have said, vital point, instead.
