Correcting Old blog URLs for WordPress blog with .htaccess

Greetings,
I am in the process of moving a blog hosted with a marketing company over to a wordpress blog to give us more control, plus I like the platform :). Anyway, our old blog used URLs such as:

blog.example.com/bid/34524/title-of-article

Our wordpress blogs are so:

blog.example.com/title-of-article

The titles are the same, but I need to remove the /bid/34524 section (by the way, the number portion of the URL was dynamically generated, so this will vary. I had tried something like so in .htaccess:

RewriteRule ^bid/[0-9]+/(.*)$ /$1 [R=301,L]

I tried many variations on this, but still haven’t found the right one. Any assistance is appreciated! ??
