This situation came up in a game between two 5 kyu players. As white, I played a tenuki since I thought black Q6 group was already alive, but after a few moves on the other side of the board I realised black was in danger.
You may as well try to check if black could have survived unconditionally if he had played first.
If you want to give it another twist, you may want to explore what would have happened it black had played N2 first. Thanks to liopic for the suggestion
