Soft 17 (A,6) vs dealer 9: the verdict

Q: Hit or stand on soft 17 against a dealer 9?

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 36.9% (push 11.3%). Full EV math for every action is in the table above.

HIT

The verdict is hit. Against a dealer 9, drawing another card carries the best expectation for soft 17 (a,6).

The numbers

Action	Win	Push	Lose	EV per $1
Hit	36.9%	11.3%	51.8%	−0.150
Double	35.6%	8.7%	55.7%	−0.401
Stand	22.8%	12.0%	65.2%	−0.423

Why hit is correct

Standing here wins only when the dealer busts, and a dealer showing 9 busts just 22.8% of the time — the other 77.2% they make a hand and your total loses on its own. Hitting risks going over, but the math nets out ahead: 36.9% wins versus 22.8% for standing, and a better expected value overall.

For context, a dealer 9 finishes on 17–20 about 71.1% of the time, on 21 6.1%, and busts 22.8%. 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 $628 per 100 such hands at $25 a hand (−0.251 EV per dollar). The genuinely expensive error here is stand: −0.273 per dollar, or roughly $683 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.
