Model used: Benchmarks below assume six or eight Spanish decks with all tens removed, ordinary player-21 priority and the usual multi-card and 6-7-8 / 7-7-7 bonuses. Strategy must match soft 17, redoubling, surrender and split-ace rules.
How a round works
Initial dealPlay begins like blackjack, but every deck contains 48 cards because the four tens are removed.
Player decisionsHit, stand, split, double, surrender and sometimes redouble under the posted limitations.
SettlementPlayer 21 and player blackjack commonly beat dealer 21; eligible multi-card and composition bonuses pay from the posted schedule.
Practical strategy
- Do not reuse an ordinary blackjack chart: ten removal and bonus/priority rules move many close decisions.
- Select an S17, H17-with-redoubling, or H17-without-redoubling strategy before playing.
- Record whether bonuses survive splits and whether drawing to split aces is allowed.

| Dealer hits soft 17 · no redoubling | 0.76% | Rule-matched basic strategy |
| No draw to split aces | +0.29 points | Change to player return from the matching baseline |
