Template conditional to identify 'target' post

[roddy]

Not sure how to describe this, but if you have a link such as
https://vborg.vbsupport.ru/showthrea...29#post1625729

Where the browser is skipping to the anchor for post 1625729 - is there anyway to target that post so you can place ads / messages there? Some kind of template conditional along the lines of < if post_id = p>
blah blah
</if>
I'm sure this must be possible in a VB conditional, I'm just not sure how . . .

I'm thinking this might be more efficient than the usual 'place ads in / after first post' method.
