Hand shape: its small gap still leaves straight draws and being suited adds flush equity when it is called.

J9s is an edge hand in 16 published spots, where the Nash solution mixes it: 9-max MP 5bb (47%), 6-max CO 20bb (45%), 9-max CO 20bb (45%), 6-max UTG 8bb (58%), 6-max CO 15bb (76%), and 9-max CO 15bb (76%), plus 10 more.
