Hard 9 vs dealer 7: the verdict

Q: Hit or stand on hard 9 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 53.5% (push 10.2%). Full EV math for every action is in the table above.

HIT

The verdict is hit. Against a dealer 7, drawing another card carries the best expectation for hard 9.

The numbers

Action	Win	Push	Lose	EV per $1
Hit	53.5%	10.2%	36.3%	+0.172
Double	49.1%	6.9%	43.9%	+0.104
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: 53.5% 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 $169 per 100 such hands at $25 a hand (−0.068 EV per dollar). The genuinely expensive error here is stand: −0.647 per dollar, or roughly $1618 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.
