I have encountered two cases of dealer manipulation of the shuffle outside the USA. Both are 6d games.

1) The first case is more obvious. The dealor used a false shuffle and basically controlled the shoe by changing how different segments are combined after each shoe. He did not use the same shuffle procedure after each shoe. He also selectively inserted some cards at the bottom of the discards and others at the top of the discards.

2) The second case is less obvious with the dealor carefully watching how the cards are mixed during the shuffle. He uses a same shuffle procedure after each shoe but is careful how each half deck is shuffled together to form a 1 deck segment.

Has anyone seen either the first or seceond case?
