I've struggled with these as well. I'm by no means an expert but I found that loosening up my range a bit has helped as well as being more aggressive on hands that I have a solid hold of than I normally would. I find a lot of people are trying to chip up fast so they are more willing to call large bets when I have the nuts or a very solid hand.
Like I said though - I'm by no means a master at this so I'm looking forward to what others suggest.
Pick your spots like in any other games. If you are on a table where they are agressive then play tight. If you are on a tight table loosen up your range. Be prepared to go on tilt and have to play short stack strategies more often but be patient and choose wisely.
