Defending Cutoff vs a HiJack open
Here you're in position on the HiJack — they've raised and folded around to you, and you close (or near-close) the action with the button-side seat. That position lets you defend 13% profitably: flat the hands that flop well (5%) and 3-bet your value plus bluffs (~8%).
Position is the whole story in this spot. You can call wider than a blind would out of position because you'll act last on every street, realising more equity. But stay disciplined against early-position opens — a HiJack raise is a stronger range than a late one.
Read the grid by cell colour: teal is a jam, amber a 3-bet, blue a flat call, and the dark fill is fold. A split cell is a mixed frequency — the solver takes each action some percentage of the time. Drill the borderline hands at the edge of the defending range; that's where the EV is won or lost.
