For people trying to use either Avant Dernier or Last Bet to choose their baccarat bets, the trick is being able to determine which kind of shoe they’re dealing with. This sometimes can be particularly difficult at the beginning when only a few hands have been played. However, at some point for many shoes it becomes obvious that they either have a vertical or horizontal bias. For vertical shoes, betting the Last Bet is the logical choice. For horizontal shoes, Avant Dernier.
