Soft 15 (A-4) vs Dealer 6: Double Down?
With a soft 15 (A-4) against a dealer 6, basic strategy says to double. This is the mathematically correct play over the long run — it's exactly what the Blackjack Trainer grades your decisions against.
A dealer showing 6 busts about 42% of the time. That's a weak up-card, which is why you lean toward standing on stiff totals and doubling strong ones — you want money on the table when the dealer is most likely to break.
Doubling is best when it's allowed. If you can't double here (for example after a split), hit instead.
