Pair of 3s is too low to leave alone against a 8. Standing surrenders the hand to a dealer who reaches a pat total most of the time, so you take the card. Your bust risk on the hit is 0.0%, and against this upcard that risk is worth accepting.
Hitting returns -0.220 per unit versus -0.511 for standing, a +0.291 swing in favor of taking the card.
It is tempting to stand on 6 and hope the dealer busts, but against a 8 that hope is too thin. Standing costs 0.291 per unit versus the correct hitting. Over a few hundred of these hands, that is real money handed back.
