Folks, part-time, non too experienced player here.

With a no-peek game and dealer showing a 10, are there any instances of hardware or software games that give the player a half-bet refund after doubling if the dealer then goes on to show a Blackjack, even if the player busts. Extreme conditions of course since I understand that you wouldn't normally want to double against a dealer's 10, more so if you're likely to bust but i'm only a bit-part player and I was just messing around with the software on freeplay.

If not then I've accidentally discovered a flaw in a major software program ha ha although I suspect that it can't be used in any major beneficial way. Got a supporting screenshot but it shows the software name so I may just keep it for my personal interest.

Definitely only works with the dealer showing a 10, then going on to show a supporting Ace. So no insurance, and no other combinations.

Perhaps I need to get out more.
