Hidan really sucks, relying to much on Kakuzu... Ok, his techniques are great, but without Kakuzu it would be very different. Maybe that's why they are teamed up.
If you look at the fact that Chouji was able to attack, this means that one of the many strategies Shika had was the breaking loose from of Kakuzu from the jutsu. This means he's taken that into account. And now what's left is the different strategy that should be implemented by Kakashi and Ino.
Kakuzu said that things doesn't always go according to plan. But I think that Shikamaru had every possible outcome covered, that's prob why the other teammembers had to memorize all the different strategies. Let's see what happens next week.
I took the advise and didn't look at the preview of next week.
