IT'S MAKE or break in tipping this week with a nightmare round set to separate the best from the rest.

There's only one unanimous choice this week with our reporters split on the other eight matches.

The race for the AFL.com.au tipping crown is coming down to the wire. Paul Bastin tipped an impressive eight last week to close the gap on Marc McGowan to just one point, while Riley Beveridge is still in the mix in third place.
