6543 in Pot-Limit Omaha
6543 is a four-card rundown in PLO. All-in it wins 41.0% against one random hand (heads-up)and 15.2% against five (6-way). 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.
Equity by suit layout

Straight potential
Straight Score: 5 (4 to the nuts). The Straight Score counts how many distinct straight categories 6543 can complete by the river — higher means more straight equity and more ways to make the nuts.
