Block View Poll Results Pages from Robots.txt

What would be the correct format to block pages like this which are giving me duplicate content issues in GWT?

Shoot don't shoot - View Poll Results

Would it be:

Disallow: */poll-

I want to be sure before I mess things up.

Hello Luke,

You should keep in mind that your robots.txt file goes into your domain root directory (site.com/robots.txt).

You can try:

Disallow: /forums/*/poll-

Thanks, that's where I'll add it.

You can test the rule within your Webmaster Tools account:

Thanks, that worked.

You're welcome, Luke! I'm glad to help.
