No method. I just do it. I was never very good at algebra or any other higher math but I have always been able to figure out simple math calculations very quickly. Maybe I should be playing blackjack
lol... I was at a table this past weekend. 2-deck shoe, but they pull the cards out of play right about the time counting the face cards gets to be useful. I prefer the craps table any day.
Best odds in the house ( except for that other card game that only stuck up snobby people play) crap is awesome. Where the fun people hang out.
The only cool person to play it. Common core is bullshit. Oklahoma threw that crap out with the trash. Back on track now.
