Chinesse ACES
This is old stuff the casinos already know.
If thereis not a mecanical device on the table to prevent the dealer from bending the Ace; which is lucrative for us players in cutting to the Ace. One can usually asume with great accuracy, that if a dealer looks twice or is somewhat apprehensive about their hole card under a 'ten up', it's generally a FOUR(Chinesse Ace); a hopeful bust hand for the dealer.
