We often see in books that Hi-Lo players have roughly 0.5% advantage on TC +2, 1.0% on TC +3, 1.5% on TC +4, 2% on TC +5 at S17 tables. To achieve such advantage, what do players have to do? I mean, do players need to use full (or Illustrious 18) Hi-Lo index plays to get these results or just flat bet using Basic Strategy is sufficient?
