I think all 5 shoes with very high count and no high cards come out is unusual situation.
One more thing that make me believe i have been cheated is they change the shoes after i finish play a normal shoes and they didn't expose any cards in new shoes - with this new shoes the count is very high and no high cards come out. I think they made a trick on this shoes for counters because they was attacked by Japanese counter recently.
Tropicana at Poipet is OK (table 100), The count at Tropicana is low or very low and sometimes you'll find the high count. I can get some money back from there. Their rule is very attractive - you can double down anytime you want - you can double down at 2,3,4 or 5 cards. However, normally, their shoes is 8 decks but cut 4 decks !!!
I never see any casino at Poipet expose the cards when they change the shoes at blackjack game. Can I ask them to expose the cards for checking ?
