Inspired by the last question about TNG ( Who's the best poker player? ), is there enough information on who the best poker player is on DS9?
I seem to recall that Jadzia Dax was (saw it on some poker article, let me try and find a relevant quote).
UPDATE: found one better - an actual dialogue from DS9 episode "Paradise":
DEEP SPACE: "Paradise" - REV. 12/08/93 - ACT TWO 14-16.
2 INT. OPS
KIRA and DAX at their stations. N.D. Supernumeraries as needed. Kira is picking up a message on her panel.
KIRA : Do you know an Admiral Mitsuya...
DAX : Best poker player in the fleet.
Next to me.
