I almost did this verbatim quote of the lyrics, which paralleled the article's sentence, and is relevant to P-hacking, but it's the wrong advice:

    Every gambler knows
    That the secret to survivin'
    Is knowin' what to throw away
    And knowin' what to keep

I don't know, maybe knowing when to "hold them" versus "fold them" and "walk away" would be a valuable skill here. The phrasing sounds off in the part you quite because in poker you only can play a given hand once, and after you've lost, you need to draw an entirely new dataset and start fresh.

[TorKlingberg]

It depends on what Poker variant you're playing. These days Texas hold 'em is dominant, but Five-card draw used to be very common, especially for informal games.

I'm not sure I understand the relevance. My point is that you can only play a hand once, regardless of the variant, and after that you deal a new hand rather than getting to go back and make different decisions on the same hand.
