I am wondering if anyone has any smart advice for this tourney situation:

7 players at a final table

1st place gets 15k
2nd place gets 7.5k
3rd place gets 2.5k
4th – 7th get 0

Everyone starts with 1000 chips, and we play 14 hands. Table min = 50, table max = 1000. Blackjacks pay 2 to 1 so each hand has +2% ev assuming you have enough chips to double/split. All 6 opponents are recreational/bad players, and they are all very likely to bet small on the first hand.

What are the keys to getting a big edge here?
