On pages 112 and 113 of MDBJ, the tc indices are given as follows: Hit 12 vs 4 at 0 or less, Do not double 9 vs 2 at 0 or less, Do not soft double A4 vs 4 at 0 or less, Do not soft double A3 vs 4 at +1 or less, Do not soft double A2 vs 4 at +2 or less,Do not split 9,9 vs 2 at 0 or less, Do not split 6,6 vs 2 at 0 or less, Do not split 6,6 vs 3 at +1 or less, Do not split 2,2 vs 3 at +3 or less. I'm uncertain if my interpretation of these strategy index related decisions is correct. Someone please help!
