Late Surrender Index per SW's Pro Blackjack p269
For the shoe game the indices differ chiefly versus an ace depending on the soft 17 dealer action. All of the below indices are for Hi-Lo, don't have the indicies handy for the other count systems...
16 v 10 TC -2
16 v 9 TC 0
16 v A TC -1 (-4 H17)
(if 8-8, use 1, 7 and -5 for 10, 9, no sur S17 v A; -4 to 5 sur H17 v A)
the above are considered basic strategy
the following are the FAB 4
15 v 10 TC 0
15 v 9 TC 2
15 v A TC 1 (0 H17)
14 v 10 TC 3
also, per pg 93 of my copy of SW's book (the 1994 edition printed 2003)
always late surrender a 17 versus an Ace in a H17 shoe game--that differs from the indice listed in the appendix on page 269
The book is easy to find at your local Borders or Barnes & Noble. It sell for about $20...thus if you want to check out the single deck indicies, or the composition dependent indicies, which are slightly different, just buy the book.
