HU hand against Baronzeus

[Lmn55d]

Baronzeus and I played this hand today during our HULA match. For those who don't know, Baron is solid and pretty aggressive. His preflop raising range is very wide, maybe top 85% of hands. I know the other hands in the match are important in determining the correct play, but I think this one is interesting in isolation.

Also, what hands should Baron be betting on the river?
