long story short, i was playing bj at a private property and i think they might cheat on the deck they were playing with.

rules are 6d, s17, no rsa, double any 2 cards, split up to twice(3 hands total), bj pays 3 to 2, no insurance, late surrender, about 83% pen.

first time playing here, my bankroll were $2000, was planning to spread aggressively since i dont plan to come back.

my spread was

1 or below = $10
2 = $80
3 = $120
4 = $160
5 = $200
6 = $240
7 = $280
8 = $320
9 = $360
10 = $400
11 = $440
12 = $480

i was just scouting around for an hour when i first arrived, then started playing using zen with some indexes. i lost the whole $2000 on my first 30 hands, didnt even go through half of the deck. the count went up high for the first 10 hands which made me bet $200-$300.

can someone sim this correctly though? is this even mathematically possible?
