Sev TNG: Riker the cardshark
Interesting strip. I don't think we see a ton of poker playing on TNG, but it's something memorable. I do wonder why chess and poker. Why not go to the arcade or something (yes, I know, these two things are cheap to produce...). An alternate proposed punchline that I also liked was "I think one thing, say another and do a third."
