After this, nobody wants to play the circled spots : Black would actually commit suicide by trying to capture the stones, and White would give life + points to the defender.
So, this is seki.
I have seen many dan players not be able to solve this problem. Apparently you can easily get stuck in your usual reading habits ... --Arno
In this case, a better sequence for Black is to play tenuki instead of playing move 2; and save it as a ko threat for later. --aigo
Since white plays the even numbered moves, I'm going to assume you meant white instead of black. If white plays tenuki instead of (or ), black can kill the two white stones inside by playing that move himself. --Bass
