hi all! it's my first post here

an online casino here in Italy is having a promotion on their live €25 blackjack table

if the player is dealt an ace-jack blackjack, the player gets a bonus equal to the original bet.
if both the ace and the jack are of spades, then the bonus is 10 times the bet instead.

the bonus is of the "sticky" type

the standard rules are:
8 decks
dealer stands on soft 17
dealer checks for BJ only with an ace up
double on any two cards
no double after split
no surrender


is this promotion nothing to be excited about, or should I play it any time I can?
thanks for your suggestions!
