Mef: I've stared at this for a while, and the best I can find is a sente reduction for white:

2 at 8  

W1 looks like the only move because otherwise back gets an easy eye. B2 forces W3, and after B4, all white can get from this is capturing the 2 stones.

JoelR: I think White can kill. Black B4 above doesn't work, because White can fill, leaving a dead shape. Black must eventually fill the weakness at circle.

Mef: If black immediately fills circle, then black will have 2 eyes by capturing at A. If white plays A, then it's no longer a dead shape and black lives by capturing at B

Dead shape 1 (2@5)  
Dead shape 2
