First of all I do realize that 2 to 1 payment for BJ (rather than the usual 1.5 to 1) is non existent except that it may be offered as a very short temporary promotion.
Assuming that such offer is made and that one is lucky enough to be there,
Is it better to bet on EVERY HAND the max bet you can afford, or
is it better to do the count (and sidecount Aces) and bet high only at higher counts and many Aces are yet to come out?
Also doesn't the number of other players reduce your chances? Or is the assumption made that every one will eventually get their share (4.75%) of hands as BJs?
