I was terrible at heads up. I ended up studying some content about playing heads up and decided to invest some time playing. I started with HU SnGs since the amount I would lose each time was a given amount. HU takes getting used to, but with experience it's pretty fun IMO because I only have to focus on one player. I don't have to worry about an entire table. I find that I can read hands much better HU than I can on a 6max or full ring table.
