I play ultra-turbo 6 person SNGS. Of the times I have places I get around 65% second place, 35% first place. I want to get the first place percent up so I need to work on my heads up. This is slightly different from MTT heads up because the blinds are up to 800-1000 with 4500k stacks by the time its down to two people. I think I'm usually good at heads up but I guess I'm not aggressive enough.

What hands should I raise with on the SB against a mostly loose opponent if we both have the same size stacks? How much should I raise? (If the blinds are around 800)
