How to read it

  • Rows are your hand total: hard (no usable ace), soft (an ace counted as 11), or pairs.
  • Columnsare the dealer's upcard, from 2 through Ace.
  • Cells are the play. When the chart recommends doubling or surrendering but the rule forbids it, fall back to the second letter (e.g. Dh = double if you can, otherwise hit).
  • Splits assume you can split. If max-splits is reached, treat the hand as a hard total of the same value.

Stop staring. Start drilling.

Reading the chart is easy. Recalling it under pressure isn't. The in-game coach catches every deviation the moment you make it.
