right so i’ve been doing some maths on this and its quite interesting actually. if ur playing at a table where all cards are face up (which some casinos are doing now due to covid where players cant touch cards), u can gain a small advantage by watching what cards other players have. specifically, if u see lots of aces kings and queens have been dealt to other players, u should call with lower hands than usual because dealer less likely to qualify. i worked out this reduces house edge from 3.37% to 2.62% which isnt massive but every little helps innit. tried this at genting in manchester last week and won about £80 over a couple hours. not saying its foolproof but worth a try if ur at a face up table. anyone else tried this approach?
