Buddy, the rule where dealer must hit a soft 17 favors the HOUSE. It gives the house an extra 0.22% edge. This would effective mean that on bitjack21.com, where the house edge is currently about 0.4%, it would go up to 0.66%... This rule is BAD for the player and GOOD for the house.
Agreed. You DON'T want the dealer making a hand of 19-20-21. Make him STAY with the 17.
