Defending Small Blind vs a LoJack open

The Small Blind faces the LoJack's raise with the whole hand still to play out of position. That flips the maths: flatting is far less attractive, so the solver leans on 3-betting (~6%) over calling (5%), defending 11% overall.

Defending too wide by flat-calling out of position is one of the most expensive leaks in this spot — you invite the Big Blind to squeeze and you play every street last. When you continue, prefer a 3-bet with your good hands and fold the marginal ones.

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.
