Examples of index generation based on sampling for SP21:
========================================================

1. To analyze:
11 vs 10 when three cards drawn:  DOUBLE vs. HIT
------------------------------------------------

Modifications in Spanish21 strategy template:

:
ENTRY { SUM := 11;  DUP := 10 ;
  CONDITIONS sp11t {
//  NCARDS = 3 := HIT ELSE a0_11t;
    NCARDS = 3 ELSE a0_11t; AND
    CUSTOM DOUBLE HIT 10 ;
  }
  CONDITIONS a0_11t {
    NCARDS = 4 := HIT ELSE a1_11t;
  }
  CONDITIONS a1_11t {
    NCARDS = 5 := HIT ELSE a2_11t;
  }
  CONDITIONS a2_11t {
    NCARDS = 6 := HIT ELSE a3_11t;
  }
  CONDITIONS a3_11t {
    NCARDS = 7 := HIT ELSE a4_11t;
  }
  CONDITIONS a4_11t {
    NCARDS = 8 := HIT ELSE a5_11t;
  }
  CONDITIONS a5_11t {
    ALWAYS DOUBLE;
  }
}

2. To analyze:
11 vs 10 when two cards drawn:  DOUBLE vs. HIT
------------------------------------------------

Modifications in Spanish21 strategy template:

:
ENTRY { SUM := 11;  DUP := 10 ;
  CONDITIONS sp11t {
    NCARDS = 3 := HIT ELSE a0_11t;
  }
  CONDITIONS a0_11t {
    NCARDS = 4 := HIT ELSE a1_11t;
  }
  CONDITIONS a1_11t {
    NCARDS = 5 := HIT ELSE a2_11t;
  }
  CONDITIONS a2_11t {
    NCARDS = 6 := HIT ELSE a3_11t;
  }
  CONDITIONS a3_11t {
    NCARDS = 7 := HIT ELSE a4_11t;
  }
  CONDITIONS a4_11t {
    NCARDS = 8 := HIT ELSE a5_11t;
  }
  CONDITIONS a5_11t {
//  ALWAYS DOUBLE;
    CUSTOM DOUBLE HIT 10 ;
  }
}
:


Player Sum= 11  vs. DUP= 10   -  Strategy entry= Hard hand
Sampled count range: -7 ... 8      Step size: 2    Max extry: 8
Play: DOUBLE  Total EV=   10.7321%
Play: HIT  Total EV=   10.6240%
++ Basic Strategy for current object= DOUBLE
++ Median entry= 4
++ C1 INDEX:  +0 , +1    (type low index)

BS= DOUBLE
Index = +0/+1

=====================================================

3. To analyze: 17 vs. A

If surrender not possble what is Basic strategy
for Hard 17 vs. A in SP21:
-----------------------------------------------

:
ENTRY { SUM := 17;  DUP := 1 ;
  CUSTOM STAND HIT 10 ;
}
:


Results:
BS=  HIT
