My Grandpa taught me how to play poker in the 1960`s. We played 5 card draw, 5 card stud, and 7 card stud (dealers choice). Our whole family gathered for poker night. At the kids table, we added a "joker" to the deck, (good for aces, straits and flushes). Texas hold`em came along later. So, I watched many a video on how to play. Because, we still have big family games (a few times per year). Also, I`m glad that I did good in my math classes at school. See you on the tables.
