Getting players This is always a challenge when getting started out. Even though my game has a solid core now, there was a time when it fizzled and died. Lots of posts on PCF discussing how to grow games.
Dealing How do I get to Carnegie Hall? Practice, practice, practice. For years, I would ask ask players new to shuffling "would you like a bucket and a stick?" But unless they have a legitimate disability (broken hand and Multiple Sclerosis have both come up), I make them shuffle when it's their turn to shuffle - deal when it's on them to deal. Repetition won't turn them into casino dealers, but they will get better. Sure, sometimes players on the ends will "need help" passing the card along. This isn't a bad thing, and it actually keeps "Chatty McTalk-Talk" focused on the game more often.
Enforcing rules Always tell them why the rule exists. String bets allow a player to gauge another players reaction. "I bet and see you reach for more chips, I can stop betting, my bluff wont get through. I see you recheck your cards, I know your hand is questionable, and I bet more on my bluff." New players understand better when they know why the rule is in place, instead of it being a nit-picky rule - and almost all rules are made to prevent angle-shooting or cheating.
