Freerolls vs dominated draws
In PLO, two draws can both 'have equity' while one dominates the other. A nut-flush draw freerolls a non-nut flush draw for stacks when money goes in.
Night drill: write three flop spots where your draw looks strong but loses to a freerolling nut draw. If you can't name them, you're not ready to stack draws.
If both hit and you lose, your 'equity' was a trap. Write that sentence on a sticky note.
