Google and pop-unders? peel-away?

[WCD Admin]

How does google treat sites who use pop-unders in the SERP?
Does anyone use them? Peel away better?

I need to convert some high-traffic NON casino pages (they are lottery pages - but lotto is not paying the bills - or I am promoting the wrong program!)

I've heard try Bingo, and maybe that's what I'll do with the pop-under or peel-away (depending on what I select) ...

Inputs appreciated!

No idea about google, serps or conversions on those, but putting on my web surfer shoes ... any site that pops up ads, pops under ads, overlays ads, tries to trick me with fake instant messenger ads etc never gets a return visit.

I 'd say the peel-away ad has less "piss off your visitors" factor and they usually look pretty cool.
