Why is A2o a mandatory open in Heads-Up play from the BTN while being a standard fold in 6-max Under the Gun (UTG)?
- Against an 85% range, Ace-high holds significant showdown value and is rarely dominated.
- In 6-max, the rake is lower, making A2o less attractive.
- The BTN in HU has 100% equity realization regardless of hand strength.
- The SPR is higher in heads-up play, allowing for better realization of the wheel draw.
