DOUBLE

Basic strategy says double. Against a dealer 4, this hand is strong enough to put double the money on the table.

The numbers

Action	Win	Push	Lose	EV per $1
Double	49.1%	7.7%	43.2%	+0.119
Hit	49.1%	7.7%	43.2%	+0.059
Stand	39.4%	13.0%	47.5%	−0.081

Why double is correct

Doubling wins almost exactly as often as hitting (49.1% vs 49.1%) — the difference is you have twice the money riding on a favorable spot. Against a dealer 4 (bust chance 39.4%), that extra bet is the whole point: EV +0.119 doubled beats +0.059 hit.

For context, a dealer 4 finishes on 17–20 about 49.4% of the time, on 21 11.1%, and busts 39.4%. 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 hit instead of double costs about $148 per 100 such hands at $25 a hand (−0.059 EV per dollar). The genuinely expensive error here is stand: −0.199 per dollar, or roughly $498 per 100 hands at the same stakes.

Does the rule set change it?

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