Soft 15 (A,4) vs dealer 7: the verdict

Q: Hit or stand on soft 15 against a dealer 7?

Basic strategy says Hit. A genuine coin-flip — the gap is under half a cent per $1. Your chance of winning with the best play is about 47.7% (push 8.3%). Full EV math for every action is in the table above.

HIT

The math is in: hit. Against a dealer 7, drawing another card carries the best expectation for soft 15 (a,4).

The numbers

Action	Win	Push	Lose	EV per $1
Hit	47.7%	8.3%	44.0%	+0.037
Double	42.6%	5.7%	51.8%	−0.184
Stand	26.2%	0.0%	73.8%	−0.475

Why hit is correct

Standing here wins only when the dealer busts, and a dealer showing 7 busts just 26.2% of the time — the other 73.8% they make a hand and your total loses on its own. Hitting risks going over, but the math nets out ahead: 47.7% wins versus 26.2% for standing, and a better expected value overall.

For context, a dealer 7 finishes on 17–20 about 66.4% of the time, on 21 7.4%, and busts 26.2%. Those dealer outcomes are the same no matter what you hold — the whole game is choosing the action whose distribution fits them best.

What the mistake costs

Choosing double instead of hit costs about $552 per 100 such hands at $25 a hand (−0.221 EV per dollar). The genuinely expensive error here is stand: −0.512 per dollar, or roughly $1281 per 100 hands at the same stakes.

Does the rule set change it?

No — hit holds across every common configuration: Vegas Strip, Atlantic City with late surrender, H17 games and European no-hole-card tables all agree here.
