From beatingbonuses:
Joker Poker, if dealt joker then
18* 6, 7, 8
19* 5, T, 9
20 Redraw (keeping Joker)
* Counterintuitive strategy relates to chance of straight and 3+ of kind
How does keeping 5 T 9 help with a straight? or 6 7 8 with 3oak?
I just realised now it probably means hold any one of those, but perhaps it should be clearer.... mebbe it's just me
