The one by Richard Turner I don't think is an actual trick, it's just him being one of the best card mechanics in the world and showing how he can cheat at cards and would probably take years to decades of practice.
As for gambling routines, I really enjoy visual card magic so I worked Shin Splint (1 or 2.0 both work) into mine. I basically say we'll play a two-player game of poker and I'll deal out two hands. They'll get a full house and I'll get a garbage hand. They've "won", but then I say something like "wait lemme try to beat you one more time. To be fair, I'll only deal myself 4 cards because penalty" or some bogus rule like that. I'll deal myself another garbage hand of 4 cards, then I'll switch those cards out for the 5 cards in Shin Splint. Then, I do Shin Splint to reveal myself having a better hand, but it technically isn't a poker hand because there's only 4 cards. The fifth card is already hidden so I just reverse it and produce it face up so that the spectators don't realize it was the fifth card in the twisting the aces part. I know it's a garbage explanation, but I didn't want to detail the method exactly.
