Blackjack strategy trainer

The trainer deals a hand and grades your decision against the solved chart for that table.

Every graded decision carries the expected value the decision cost you.

The trainer is free and it needs no account.

Session review

Silent mode shows every grade here.

    No decisions recorded yet.

    Three feedback modes

    Strict mode blocks an incorrect decision and explains the correct one before the hand continues.

    Advisory mode allows the decision and flags the mistake straight away.

    Silent mode grades every decision and reveals the whole session at the end.

    What the cost figure means

    The cost figure is an expected value in units of the original wager.

    The cost figure is the value of the correct action minus the value of your action.

    The cost figure is not a prediction of your result over one session.

    The severity bands below sort each cost into one named level.

    Severity bands

    The coach module sets the bands and the trainer renders each band label.

    1. No cost
    2. Almost no cost
    3. Small cost
    4. Costly
    5. Very costly

    Weakness targeting

    The deal is weighted toward the decision groups you get wrong most often.

    Every hand still comes from the rows of the chart for your table.

    Coverage of the rule sets

    23 rule sets have a solved chart, so the trainer grades them.

    9 games are dealable and ungraded, because no solved chart exists for them.

    Each of those games changes which play is correct.

    A chart from another game would mark correct decisions wrong, so the trainer refuses to grade.

    What the trainer does not claim

    The trainer measures your decisions.

    The trainer does not predict your results.

    We publish no certification and we make no claim about profit.

    The trainer is for adults aged 18 and over. Play responsibly.
