Unfortunately, it’s possible your apparent lack of knowledge is so broad that no one knows where to start with you.
The first thing you need to do is memorize the basic strategy for the number of decks and rules you’ll be playing with. Someone from the UK ought to chime in here and advise you on the settings for the
Basic Strategy Engine.
The second thing to do would be to go play, so you’ll have some idea of what’s going on with this game you’re trying to learn. (Some people would insist that you shouldn’t set foot in the casino until you know how to play at an advantage, e.g. card counting. I personally think that’s unreasonable to expect of someone who has never played before.)
After you have BS (basic strategy) down cold, and have a little experience under your belt, then you can start looking into counting cards.
