Recently had a dealer that was convinced that Spanish 21 was a "better" game at the casino I was playing in. While I was playing Blackjack, she seemed pretty aware of my play and might have been counting the shoe along with me. Does anybody have any experience finding a Spanish 21 game with a lower house edge than table BJ? Does this edge become negligent when trying to implement winning strategy? Any resources or methodology behind calculating house edge and deviations would be appreciated. I have been considering developing my own tool to test this theory.
