I'm sure most of you guys know this but the shuffle machines have been "tracked" successfully (even thought he algorythms have since been fixed) AND shuffling machines can be counted.
It is not a very high +EV game. There are two large advantages though.....
1) Nobody will question you if you spread 20 units or larger as "it is a shuffle machine, nobody can beat it"
2) The technique is not very well proven but it is incredibly easy.
I don't think you could make a living from it but you could enjoy a few hands and spread your bets without worrying about heat?
I'm not sure if this is reallyw aht this thread is about, I just thought I would give my penny's worth :)
