Bold text within bold text

does it help?

I am trying to optimize my site and wanted to increase my search word density. I wanted to try out this code:

<B>We have many <B>widgets</B> in many colors</B>

Does anyone know if this helps with google - will it give extra-extra weight to "widgets"?

Since ultra bold is a unknown html attribute and doesn't make sense, i'd rather use italic instead.

Can you see the difference:

We have many widgets in many colors
We have many widgets in many colors

However, i don't know, if this helps your rankings.
