Play hands against a dealer up card and see every decision graded against the published basic strategy chart for the ruleset you select. No money, no accounts, no stored data.
A shoe is dealt in your browser. You receive two cards, the dealer receives an up card and a hole card, and you choose hit, stand, double, split or surrender. Only the actions legal for that hand and ruleset are shown, so there is no double on a three card hand and no split on a hand that is not a pair.
Every decision is graded immediately against the basic strategy chart for the ruleset selected. When the answer is wrong, the trainer names the correct play and the expected value difference between the two plays in that exact spot.
The chart is structured data generated from two published sources, the Wizard of Odds basic strategy calculator and the BlackjackInfo basic strategy engine, compared cell by cell. Across the 14,400 cells covered here the two agree on all but one, a pair of eights against a dealer ace in a two deck game with the dealer hitting soft 17 and late surrender available. Both answers are accepted for that cell rather than one being picked silently.
Expected value figures come from the Wizard of Odds expected value appendix, one table per deck count and soft 17 rule. Costs are per hand and assume the stake you set.
No. Basic strategy lowers the house edge to its minimum for the rules in force, often below one percent, but the edge remains against the player. It reduces the expected loss, it does not remove it.
The chart is computed from the probabilities of the specific game. Deck count, whether the dealer hits soft 17, whether doubling after a split is allowed and whether surrender is offered all change those probabilities, so they change which action has the highest expected value in a number of spots.
It is the published expected value of the correct play minus the published expected value of the play you made, for that exact hand against that exact dealer up card, multiplied by the stake you set. It is not a flat estimate.
No. Nothing on the page is a wager. The stake figure is only a multiplier used to express expected value costs in currency terms, and no data is stored or uploaded.
