If black reduces from outside first...  

White is now alive :(

From the other side...  

After 8 White will have an extra liberty to win the race and live :(

Alive by 1 Liberty  

So we will have to go back to the original situation... Black needs to be a bit more sneaky :D

Sneaky Sneaky  

After this move White is already dead he has no resistance that allows him to live... Not even a Ko :D

Cutting off Black...  

Snapback! HAHA!

Cutting more solidly...  

More of the same snapback shape :) And since if White doesn't cut Black just connects out and White doesn't have enough space to live inside... hes dead!
