Understanding the nature of dozens is the only way to go when betting on them, unlike 1/1 bets which will go red black red black red black red black red black the dozens don't like to do 1stD 2ndD 1stD 2ndD 1stD 2ndD, they also don't like to go 3rdD 2ndD 1stD 3rd 2ndD 1stD 3rdD 2ndD 1stD
It's understand what they don't like to do that's important, so if you see a symmetrical pattern forming like 2nd 1st 2nd 1st 2nd 1st just bet against it with the other 2 dozens.
