Best Move by Ruleset
Best move: HIT. These examples use six decks, H17 (dealer hits soft 17), DAS (double after split allowed), doubling on any initial two cards, no surrender, 3:2 blackjack and U.S. dealer-peek rules. This is an initial, unsplit ace-and-7 hand. The recommendation is an educational chart decision and does not predict the next card or the result.
What happens when you draw another ace
Drawing an ace gives 19: ace, 7, ace is soft 19, with one ace counted as 11 and the other as 1. Drawing a 2 gives soft 20; drawing a 3 gives soft 21. A 10-value card gives hard 18 because the ace must then count as 1.
Recalculate after every card
A soft 18 cannot bust on its next single hit because the ace can switch from 11 to 1. That does not make every resulting hand strong. Identify the new total and whether it is still soft before making the next decision. Doubling after a hit is unavailable under this profile.
Quick Checklist / TL;DR
