Essential to the greater good of your game, is the simple understanding of poker rules. Be your knowledge for use at big fancy money tables in Vegas, or for family fun night with big jars of pennies... Knowing the difference between Texas Hold'Em & 5 Card Stud is muy importante! That, and a basic idea of the value/chronology of each hand.
I may not be big on gambling, but I understand the value of good old fashioned fun. It's all about balance folks. So set yourself some limits, brush up on your skills, and hit the tables. Or, better yet, dust of the card table, make some appetizers, invite over some friends, and start a game night exchanging coins, small tokens, or just really good stories!
