Not too long ago I bought the kindle edition of Casino Tournament Strategy by Stanford Wong. In the beginning of chapter 2 he presents a generic strategy chart. You can see this basic strategy chart at Amazon and they let you see the first few charters of the book.

Anyway what jumped out at me is he says A2 (soft 13) vs 5 is a hit. I always thought it was a double down on both S17 and H17 games. What is right? You can check out the chart at Amazon and look at chapter 2 without buying the book.
