The game is a normal blackjack game with side bet Over/under13, which is dealt with CSM one2six, no rebate

Blackjack EV: -0.17%

over 13 EV: -6.55%

under13 EV: -10.07%

By card counting, TC is hardly to +3, at +3, O13 have +EV 1.55%

Can anyone have some new method such as card tracking???

If we can predict the picture cards i.e. 10 -valued card, bet on O13 will have 75%win

If we know one of the 2 cards is either Ace or 2, 100% sure win for betting on U13!!! (any combinations with A or 2 must be under 13)

Any suggestion???
Thank You
