Yes, it's possible to win in blackjack without using basic strategy, but it's much harder and less reliable. While luck can sometimes lead to short-term wins, ignoring basic strategy increases the house edge, making long-term success unlikely. Basic strategy is designed to minimize this edge, and without it, you're more likely to make suboptimal decisions that favor the house. While card counting can give you an edge, it still requires basic strategy as a foundation. Overall, while you may have some luck, the odds are against you in the long run if you don't use basic strategy.
