Is this seki?

Japanese Rules

Under Japanese rules its a seki. See [ext] Example of a seki with 1 (false) eye in total.

Pretend it's black's turn to move first in this position. Does black have a useful move to capture the white stones? Now pretend it's white's turn to move first in this position. Does white have a useful move to capture the black stones? If the answer to both of these questions is "no", then it's a seki.

Chinese and Ing Rulres

Under Chinese rules and Ing rules, Black receives one point for the empty circled intersection in addition to the points received for Black stones on the board at the end of the game.
