7643 in Pot-Limit Omaha
7643 is a four-card rundown in PLO. All-in it wins 42.3% against one random hand (heads-up)and 14.6% 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
The same ranks play very differently depending on how the suits line up. Each layout shows equity all-in versus one random hand (heads-up) and versus five random hands (6-way), from 400,000-trial simulations.
Straight potential
Straight Score: 6 (5 to the nuts). The Straight Score counts how many distinct straight categories 7643 can complete by the river — higher means more straight equity and more ways to make the nuts.
