When the dealer hits soft 17, the house edge is slightly higher than when the dealer stands on all 17s. This is because the dealer's chance of busting when hitting soft 17 is lower than when standing on all 17s. Therefore, the house edge for hitting soft 17 is typically around 0.2% higher than for standing on all 17s. For example, in a six-deck game, the house edge for hitting soft 17 is approximately 0.64%, while the house edge for standing on all 17s is approximately 0.44%.
