Greedy players usually double down it but standing or hit one more time is the best choice here if you are playing with limited funds. You need to play the game slowly to make sure that you can secure profits with the 1mbtc free bet.
Nothing wrong with not doing hits.
Because you playing with the books, most of us will double down because have a small card for the dealer. I also are gonna to do the same things (will double down), anyone who currius about gambling strategy.
Go to google and search "Blackjack Startagey by Casino Ground".
It depends on the faced up card of the dealer if you will double down on soft 17 or not. Remember that Slaman didn't mention the faced up card of the dealer and you just assumed it was small. I'm assuming that dealer faced up card was 7 to 9 when I made the comment above since Slaman still hit at soft 17. Slaman provides only the data that the dealer total card was 11 and when the dealer hits 6 to make 17 which means there's a chance that dealer faced up card is around 7,8,9 too and not only 6 below that's why I'm checking this info to him on my above post.
