With a 6-deck game, the house edge for PP is much lower than for the Big Wheel or Gaming Machines. Though a CSM seems a bad thing to BJ players, it is not that bad in terms of PP. * For simplicity reason, Perfect Pairs will be shortened to PP in all subsequent passages.
According to my experience, the majority of time when I play BJ with CSMs, at lease one Perfect Pairs appears (within 30-60 hands), plus many other pairs (coloured pairs and mixed pairs).
