Party Poker 10/20 Hold'em (6 max, 5 handed) converter

I'm struggling in adopting to the aggression level at 10/20, one second everybody's got nothing next minute I see nothing but the nuts (or there about). In my attempt to adjust I play hands like these, completely out of line? Should I just take my free card on the turn etc.
