The Simulator takes a given basic strategy(BS) as input (defined in a .csv-file) and simulates the win/loss against a random shoe with user entered number of decks. The sim counts cards using one of 3 card counting systems selected by user. Depending on the current count, or other settings, simulation will adjust the bet size.

SHOE-1: Win:15 Lose:27 | 45 Hands inc/Splits - $-350.00 | $9650.00
SHOE-2: Win:16 Lose:26 | 46 Hands inc/Splits - $525.00 |
