Example: payout dominates

A single-deck label can look favorable, but 6:5 blackjack can cost roughly 1.4 percentage points relative to 3:2. That normally overwhelms the deck-count benefit.

Example: S17 versus H17

Standing on soft 17 is favorable to the player, but a complete comparison must keep deck count, doubles, splits, surrender and payout fixed.

Example: surrender

Late surrender can lower expected loss only when used correctly. A table offering it does not help a player who never takes the option or uses the wrong chart.

Example: ENHC

When all wagers lose to a later dealer blackjack, doubles and splits carry extra exposure and strategy changes.

Best workflow

Enter a supported complete profile in the rules engine, open the matching chart, then price the intended session.

Frequently asked questions

Why does the exact rule set matter?
Because probabilities, legal actions and settlement can change together. A result belongs only to the model it analyzes.
Does better strategy guarantee profit?
No. Strategy selects the highest expected-value legal action; the best available action can still have negative expectation.
