Single Deck Draw Hi-Lo

I was playing a table game, draw hi-lo on AbsolutePoker.com(UB.com) and was looking around Google for literature on it but I couldn't find any due to articles mainly about poker hi-lo variations coming up instead.

Does anyone know the house edge and/or optimal strategy for the game? I checked WizardOfOdds but couldn't find any material there either. Thanks.


PS. Here is a URL for the same game UB uses , just on a free site: link removed.
