In baccarat, there is about an equal chance of either the Player or Banker winning a given hand. Baccarat players can use this to their advantage by picking one side, either the player or the banker, and then sticking to it. That is what the One-Sided strategy is all about, betting only on one outcome that is likely to win.
The Banker bet has a 1.06% house edge and a 45.9% chance of winning, while the Player bet has a 1.24% house edge and a 44.6% of winning. Betting on either of the two will give players a nearly equal chance of winning.
The strategy also depends on the assumption that the hands will not easily alternate line “Player-Banker-Player-Banker” and allowing the gambler to win several hands before the outcome changes.
