6543 in Pot-Limit Omaha

6543 is a four-card rundown in PLO. All-in against a single random hand it wins 41.0% equity — stronger than 9% of starting hands by raw equity. Rundowns realise more than their raw all-in equity suggests: they flop straights, wraps and big draws and make the nuts often, which is where their value comes from.
