This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Other way around. 10 point cards favor the player. From Wikipedia:

  • They increase the player's probability of hitting a Blackjack, which often pays out at 3 to 2 odds (although some Casinos pay at 6 to 5).
  • Doubling down increases expected value. The elevated ratio of tens and aces improves the probability that doubling down will succeed. The most common hand values that the player doubles down on are 11, 10, and 9; and drawing a high card to these will make a strong hand.[1]
  • They provide additional splitting opportunities for the player.
  • They can make the insurance bet profitable by increasing the probability of dealer blackjack.
  • They also increase the probability the dealer will bust, in the event that the dealer shows a low up-card (i.e. 2-6). This also increases the odds of the player busting, but the player can choose to stand on lower totals based on the count.

You can just keep a tally in your head adding or subtracting a number when certain cards are played. Doesn't require that much skill. The skill is in pretending everything is normal that and half of the people who just joined the table just met you for the first time.
