A negative result is surprising--the rules you stated certainly give a basic strategy player a small advantage. I've never used PBA, but my guess would be that the basic strategy you're using for the sim either doesn't have the proper European no hole card adjustments or doesn't have the proper early surrender plays. For what it's worth, 20 million hands is a pretty small sim, but it's very unlikely that would account for the negative result.

What is the penetration?
