The internet is full of info you need to study as much as posible and then adapt thouse infos to the tipe of person you are. Agresive, pasive, tight, loose. In the end you will be your real teacher by practice.
My Great-Uncle taught me. I was raised by Great-Grand-Mother. Her son who was an alcoholic also lived there. He was in World War Two and never got adjusted to civilian life. Anyway we were dirt poor so he and I would play poker for match sticks some Saturday's nights. And there you go...
Started playing years ago with my buddies. We would get together for a game every second Friday night. We were BIGGGGG spenders. ha Ha Each of us brought $20 to play straight poker. Ended the evening with a meal and dessert at midnight. those were the days !!!
My best friend, what happened very quickly is one of my first serious card games. Since then we are going and playing for a bottle of beer, our little tradition))
