You sent me a video of your opportunity. It's real. But it's also too rare. Even if the dealer exposed cards the way your video showed it is not something that could be consistent unlike card counting in blackjack. And since seeing the cards comes AFTER you place your initial bet the reality is you're only hoping that the dealer will make the same error so you can increase the bet in the hand you're playing at that moment. In other words you're gambling that the dealer will keep making the same error. Is that really an advantage play?
