Hand rules are still Omaha

You're playing pot-limit Omaha: four hole cards, must use exactly two with three board cards. Nothing about the tournament changes that rule.

If you can't read Omaha showdowns yet, go finish PLO Cash Kindergarten first. Tournament pressure on top of misread nuts is how you bust for free.

PLO MTT combines Omaha nut discipline with tournament ICM. Early spew with second-nuts is how you gift the field chips.

Same 2+3 Omaha construction, different economy: rising blinds and elimination. Non-nut stack-offs early are gifts to the field.
