Greetings, I have been playing several hours a day in a blackjack promotion that pays 2 to 1, I have read that this simple change can give a 2 percent advantage, the rules are 6 decks, early surrender, 80% penetration, I would like to know what it would be the best way to attack this game. They have recommended me to play 2 hands at a time and only use basic strategy but I have been doing this for a while and I don't see positive results. greetings,
