Carlton played dumb in the wet last week, but have their best chance in sometime of beating their old enemy Collingwood in round 19.

The question Andrew Wu and Peter Ryan pose to tipsters is whether this is the game to take a risk on as they seek to salvage their season.

If not, can North Melbourne upset Melbourne at Marvel, can St Kilda break their drought in Geelong, will the Crows topple Sydney and what are the chances of Gold Coast rectifying their fall against the Western Bulldogs?
