how much is this promo worth- 3 to 1 payout for A & J of spades or clubs. My quick calc is not much. on Sd, there are 64 combinations to make a blackjack (4 aces, 16 tens). The bonus only applied to 2 of the 64. A 2:1 blackjack bonus adds about 2% in EV, so figure this adds 3% on EV on 2/64. Sounds like only about 0.05%. Not much to get excited about if my math is close.
