Trying to track down a blackjack trick

[katterfelt0]

Hello All,

I swear this was in Genii, but nothing I use as search terms finds it. It was a blackjack trick with the aces and jacks placed various positions in the deck, then those two cards are forced and a dollar has the prediction "BLACKJACK" written on it, with the A and the J circled.

Any help greatly appreciated.
