Which rules is this chart solved for?

The rules are listed in the rules table on this page. The chart is solved for that exact table and for no other table.

Is this chart correct for a different number of decks?

No. A chart solved for one deck count is not published for another deck count. Use the chart page for the table you are playing.

Where does the house edge figure come from?

The figure is read from a published source. The source is named in the sources list on this page. No figure here is estimated.

Does this chart include card counting deviations?

No. Every cell on this chart is basic strategy. Counting deviations change cells and are not part of a basic strategy chart.

Verification

Every cell was compared against a published reference chart. The result of that comparison is below.

Result: One or more cells disagree with the reference chart. Each one is listed below.
Cells compared: 360
Cells excluded: 0
Cells that disagree: 1
Reference chart: Wizard of Odds

Cells where the reference chart disagrees

The chart above shows the solver action in every cell. The cells below are the cells where the published reference chart states a different action.

The margin is the gap in expected value between the two actions, in units of the first bet.

Each margin below is smaller than the known error of the solver model named beside it. On a cell inside that error, the published chart is the better authority.

Your hand	Dealer upcard	Solver action	Reference action	Margin	Model with the known error
Hard 11	Dealer ace	Hit	Double	+0.002	Perfect continuation after a hit
