I have been getting very good with moving from making top 3 to heads up in sit n gos consistently. Now im having trouble winning and only coming in 2nd. Can some players in here please give me some insight on how to become a better heads up player. I normally raise 4xbb in a tourney, I think this is too much now to raise heads up. How much should I raise, and what hands can I raise? And even if im short stacked shoud i consider raising mediocre hands heads up? Please help me out
