After consulting with my old buddy, former Bristow helicopter pilot and now a luminary in Kuala Lumpar social circles, Dato Steve Day, the answer(s) is/are:

Crossword clue: For a Polar Bear, worse than being left pawed (2, 6)

The simple answer is NO THUMBS. Polar bears through urban legend are said to be left handed. They are also known for hot having opposable thumbs. I believe that this is the answer the simple person who wrote the clue is looking for.

But if you want a cryptic answer how about this?

"AN ATTACK"

"For a Polar....Bear....."

- a Polar = a northern = AN
- bear = to bear against (i.e. as a lion bears against his prey) = "ATTACK"

An attack is "worse than being left pawed."

On balance, however, the answer is NO THUMBS,
