Looking at MvcFormAntiForgeryPost.cs and HtmlHelperExtensions.cs, I see nothing different from ordinary forms.

What HTML does the BeginFormAntiForgeryPost emit? Can anybody shed light on this?

If you look closely at the emitted HTML (using the View Source feature of your browser) you'll see that not only has a <form> element be generated, but a hidden field as well that will contain an anti forgery token value that prevents cross site request forgery attacks.
